  2. That's quite a fish trap!
  3. The plants in my rafts are starting to show yellow. Generally i think this is iron deficiency but I had added a couple of tablespoons of iron chelate about 3 weeks ago so i didnt think that was the cause... i tested ph and nitrates to find was 7.9 and nitrates are 5ppm. i know plants like ph lower (high ph can inhibit plants from uptaking iron even though there is iron in the water) but i usually dont worry much about my ph being a little on the high side... however. 7.9 is high even for me. I think i must have added a bunch of limestone or whatever when replanting the gravel bed because (when i added in a lot of new expanded shale.) I have started dosing with muratic acid to start bringing down the ph.. i will try to get PH stabilized in the 7.2-7.4 range over the next week. I also added another tablespoon for iron chelate but this time more local to the raft beds than in the sump like last time. 5.0 ppm nitrates was also surprisingly low to me. But i guess the system is still maturing. In the test kit that is an orangish color but in 8 years every nitrate test i have ever done my aquaponics systems have always been some shade of red (20ppm or higher) ... So i have moved the rest of the fish from my indoor/garage rearing tanks outside and I have started trying to feed more. I still feed twice a day and no more than they will eat in 5 or so minutes... The good news is Is the temps are still warming up and the fish have been getting more comfortable coming to the surface when i am standing near the tank so they have been eating more. I have also ordered some organic magnesium sulfate but i havent added it yet. I want to see if lowering the PH and increasing feeding solves the problem.. I am already changing two variables i want to still have kind of reasonable idea of what step solved the problem as opposed to changing a bunch of variables and having no idea.
  4. Cecil, yah, i am constantly considering how to improve my backups.. A guy on BYAP has also suggested the aerator on a relay/battery solution that kicks on backup air pumps if power to the relay goes off. I may end up doing one or some hybrid of those types solutions but my biggest obstacle is that my large system is outside but another system is in my garage... the pumps and fish tanks that could use a backup solution are not close together which means i dont think one solution will cover it all. And multiple is cost prohibitive considering i think i am in a place that i can recover, even if i have to call a neighbor to go tug the rope and start my generator
  5. Someone wanted to see the root of a plant growing in aquaponics sand culture..here is a portion of it.
  6. Yesterday
  7. Hi I'w had problems to access the forum for 2-3 houers ? cheers
  8. Last week
  9. The closer the sump is to the fish tank the less work is needed to get the water to the fish, a siphon overflow then can take the water to the grow beds by gravity.
  10. Does the brand of fish food used impact the organic certification ?
  11. How is your search going ? I am surprised there were no responses. For myself I would put it together as there are so many components available now. I am in northern Michigan so there is a limited growing season. And I am thinking that might give an advantage to the Blue Gills, but the only real answer is to try both species for a cycle .I am looking at a mix of greens and see which do best in this system. The hoop house will not be heated beyond keeping the water lines above freezing. How large a system are you looking at? I am planning a small system, mainly because of age, and just want a system to supply family and friends. So my tanks will be Rubbermaids, and growing beds of reinforced plywood with pool liners. And the sump a large Rubbermaid pool/tub. I will house it in a hoop house, 12' by 20'. I am planning initially two linked systems for two species to see which does better in my situation, blue gills and yellow perch. I am planning a flood and drain system. The high point of the beds will be at the far end, with the deeper ends draining into the sump at the near end and the tanks above on blocks, the sump will be dug in just a bit more more then the tanks are elevated. I am planing on foam insulation for the below ground parts of the sump. The sump will pump directly into the tanks, raising the water level in them and the overflow will go from the tanks to the grow beds. Thats as simple as I can make it. How does this compare with your plans? I would also like to hear from others in how this compares with their systems.
  12. starting next year. Need to do some serious catch up work in my fish taxidermy business first. Been spending too much time with the live fish! I see many advantages: 1. More control in success rate and numbers. And although I don't need high numbers for my niche market I do find the hits and misses of fertilizing a pond and depending on the weather getting old. 2. Less labor. The seining of the ponds to remove fish can be a pain in the ass and is not 100 percent successful. Some species like tilaipa are very good at evading nets. 3. No dealing with unwanted macrophyte growth as in the ponds that makes seining difficult. Also not chemicals need to be purchased or used. 4. Can use the ponds has holding ponds for broodfish swimming free or in floating cages. Separate sexes. I.e. male crappies with male bluegills with make yellow perch in one pond. Females of all species in another pond. Broodfish can be removed via hook and line as not many are needed. Disadvantages: 1. Will need to produce a live source of feed for fry before feed training for a few of the species I culture. 2. More tanks etc.need and some intensive labor initially vs. letting fry fend on their own in the outdoor ponds feeding on naturally produced food. 3. Some species may be difficult to spawn in a tank. OTOH it can definitely be done. There will be a learning curve although I plan on using all resources I can to learn from other's mistakes. Thoughts?
  13. Progressive is the wrong word to use in Texas. LOL I support the bill.
  14. Cool device! Have you considered one of these for automatically backing up your AC? I have one at home and two at two high schools. I found a place on line to calculate run time based on the number of batteries wired in parallel. Gives me piece of mind when I am away or in bed at night. I've never been let down. I saw a few bad reviews but as usual it looked like the people didn't know what they were doing. I guess nothing is idiot proof. https://www.amazon.com/Tripp-Lite-APS750-Inverter-Charger/dp/B0007PGAG6/ref=sr_1_sc_1?ie=UTF8&qid=1495886070&sr=8-1-spell&keywords=Triplite+APS+750+inverter
  15. Bllooming Innocence water lily in Aquaponics koi sump tank.. With pure white petals, it stands high above the water. @Circle of Life Aquaponics, Chennai
  16. For lunch today..assorted red/green amaranth and bottle gourd from our Easy trial systems. Chinese potatoes are on second yield trial with spacing and feed rate changes.
  17. If you have watched my threads you have seen that i have lost fish in the past due to power failers and when gfi/breakers trip... i have no doubt i have lost several hundred dollars worth of fish over the last 3 or so years.... as i ramp up, it was really important to me to mitigate this risk. just think 9 months form now i could have about 100 2+ lb channel cats and 500 bg/res/crappie at .5-.75 lbs... if i was to buy fish of that size it would be over a thousand dollars.. not to mention the emotional loss of spending a year raising fish and them all being used as compost. So i have invested in a two part strategy for monitoring.... 1) there is an audible alarm that sounds if the circuit goes down 2) I found this little doodad online that will text me when there is a power outage...It was actually made to detect flooding in basements, but it also alerts when it loses power... So i have it on the same circuit as my aquaponics and i put the sensor next to my hot water heater.. So as a bonus i have it keeping an eye on that for extra value... its a couple hundred dollars and the cell phone subscription is about 50$ a year but i think its easy to tell how worthwhile it is given the value of what i am protecting.. When it loses power it text my two cell phones, one of which also sends me emails.... if i am at home and asleep i probably wont hear/wake up to a text and an email but i the audible alarm is definitely loud enough... If i am at work or not at home when my power goes out (it always seems to happen during the day/morning when the cable company is digging, amirite?) i should be able to get home and handle the situation. I have higher density than most but it's not really that high.. i should have 2-3 hours to get home and get the generator running before things go really bad.. Maybe only an hour in the hottest days of summer, but i work only 35 mins away....
  18. Hi Aufin, blasting sand is fairly expensive, twice or 3 times the price when purchasing from homedepo or lowes, and it will be another research project to find local provider for such quality sand. i think i will stick to the quarry order and get it processed this week. i feel i have done plenty research for the local source and ended up finding something 51 miles away. many can claim its easy to find sand, well not the right kind of sand that will #1 drain properly over time, #2 allow furrows to flood consistently, #3 provide oxygen as it drains retaining it to feed the good bacteria that is key to the system and #4 survives the times! that is beside the fact it must be inert and doesn't cause disbalance to ph. not much room to choose how it looks i was fairly obsessed to find the right sand, determined and tried to follow all advice based on reason and analysis to come to best conclusion from my understanding. i might be over-analyzing things but i dont have any better guidance than what i got from various forums. not much of a local source to give me face to face advice and react to questions in real time
  19. Have you asked about any sand blasting sand? I ran into the same issue with "custom" mixes. I settled for a few yards of 6/20 coarse blasting sand. Might be a little bit outside the optimal envelope, but my setup has been working just fine with the 6/20.
  20. Hi again Sounds great IMO this is your final sand mix then (for those unfamiliar with the US grading/inch) 40% #12 0.0661in= 1.67894mm 40% #20 0.0331in= 0.84074mm 20% #30 0.0234in= 0.59436mm cheers
  21. When i was in college, i built a 3 stage homebrew station. I made lots of beer with that rig. But alas, i have not used it in over 5 years. The copper was turning green and the plastic on the motors was cracking. Its time to either clean it up and repair it or throw it away and since i dont use it there was really no decision to be made. I was staring at it trying to figure out if i need to call bulk trash pickup or if i can cut it down into small enough pieces to fit in a can... when i was like... why not reuse it. The structure will last forever.. so, i unmounted the motors, cut off all the copper and turned it into a seedling starter table. Which can also be used as the first stage to harden off plants i started indoors. On the side of the house there it only gets 3-4 hours of direct sunlight every day (at most). The roof is really intended to keep the runoff/drip from house from pelting the plants not so much for shade.
  22. Cecil, I certainly want to hear about your feed training crappie. I have my own feed training crappie 2/.0 going on in my garage, I just havent had time to compile pictures or videos to show it off. I will be moving some of the crappie to an outside tank this week so i will get a count of how many i was able to feed train out of 200.
  23. so i got a quote back for the spec combination which is a custom order. its pricey, however, its 5 yards, i might as well stock up on this sand if i am to continue to do IAVS with lack of good sources around. i dont know, the problem with local sources is their aggregate is fairly mixed of wide range or sand sizes across the spectrum. they dont exactly have consistent combination. in most cases their particle sizes are too fine. the pricing from local providers for random aggregate is 3 times less, however, getting consistent aggregate from homedepot, lowes in bags will be 500$ more ontop of what i am paying from quarry with delivery. so get trash sand for 3 times less and risk it or get custom order for 3 times more or get it in bags for almost 5 times more than the cheapest solution.
  24. i am probably annoying the quarry sales person with my "custom" order questions for "small" 3 cubic yards of sand (comparing to what they order in minimum, around 20 cubic yards)
  25. Thank You Vkn, i have been in contact with quarry to see if any providers that order from them have similar aggregate of what you mentioned. i am definitely making sure i make the right choice without being too hasty

  27. Goats are pretty funny, and provide a lot of entertainment. They are also fantastic at cleaning up weeds and overgrown brush. They aren't entirely maintenance free though. Deworming when needed, hoof trimming, etc. The lowest maintenance are typically Spanish goats, Myotonic goats and Kiko goats. If you're going to keep a couple of males, it's best to get wethers (fixed goats). Intact males stink pretty badly, especially during Fall rut. For wethers, I think Bokis (50% Boer, 50% Kiko) are also fantastic.
  28. I saw the funniest thing driving by a farm with goats. It had poured rain earlier and the goats were in a shed. As I drove by a soaked one popped his head and and looked up at the sky. As if to say, "does it look like it's going to rain again?" I've thought about getting a goat or two to keep some of my pond banks trimmed. Anybody have any suggestions on what kind? I don't want them to reproduce so may a couple of males?
  29. Mike/Ande, I know this is a late response but then if I were to choose, I would take 20% of #12, 60% #18, 20% of #35 and then mix it thoroughly. I am not saying that some other particle size distribution will not work. This arrangement really is helping in lateral water movement.
