  1. Hi again Got it, it's a DWC system UVI style built on site. It can be used for either aquaponic or hydroponic so you don't have to use fish to run it. here is a description of what you got https://www.uvi.edu/files/documents/Research_and_Public_Service/WRRI/UVIAquaponicSystem.pdf From the pics it looks like it's nicely built so does the green house. here is some more info https://www.nal.usda.gov/afsic/aquaponics?page=1 https://www.agmrc.org/commodities-products/aquaculture/aquaponics http://factsheets.okstate.edu/documents/srac-5006-economics-of-aquaponics/ I would contact the local agricultural extension office https://extension.wsu.edu have a chat and ask their opinion cheers You might get some pro/con thoughts and ideas by plowing thru this thread
  2. Hi again Gundog I downloaded the file but couldn't see any thing (wouldn't open) Could it be a Nelson & Pade system ?https://aquaponics.com/aquaponic-systems/commercial-systems-3/ see if you can recognize it See if you can identify any brand names on the pics you got, if it is a commercial system the vendor might also offer support cheers
  3. Hi Gundog Welcome to APN/HQ To answer your Q's, you have to provide more details/pics type of setup "brand-names" etc.also what part(s) of the system is missing (25%) but I'll try to give a "general" answer. Not hard, if you are dedicated and are genuinely interested, experience and/or basic knowledge in either agri- aqua- culture or both would help. Time intensity will vary with "season". Keeping livestock will tie up some time on a daily basis, no matter how much you automat the system. It could be, however it deepens on numerous factors. The upside for you is the $300.000 invested (if it is put in a "good" system you can use?) You have to figure out how much more you need to invest to get it up and running. The cost of the remaining 25% does not necessary mean another $100.000 it could be more/less, pluss the cost of your own training time and fees? Water budget is the most important part, can you get enough ? any restrictions on supply ? Access to market is vital (distances & demands) ,also what can you grow in your climate? indoors/outdoors/heating/cooling/lighting etc.......? Regulations ? restrictions ? on fish species, supply of fish................. the list is long, there are a few threads on the subject worth reading. https://wsg.washington.edu/wacoast/meetings/June-2016/Handout-Overview of State and Federal Aquaculture Requirements.pdf Short answer to both is yes. No such thing as dumb Q's so don't worry cheers
  4. Hehe I see I got those pictures in a odd sequence I'll add that before proceeding to make the jelly, I did a test run as I'w never made jelly before. The test badge was made of mint picked in the garden, turned out really nice as well and boosted my confidence to make the rowan jelly cheers
  5. Hi again So I picked another +5kg badge for the freezer. Most recipes I found, recommended a mix with apples do to the bitterness of pure rowan jelly so that was the next step. First pick some apples and make juice tossed the apple juice in the freezer, next step pick up the frozen rowanberry and make rowan juice Then I went on with the actual jelly production I decided to make two different. One pure rowan, and one 50/50 mix rowan/apple and true enough the mix is indeed a sweeter jelly (but still bitter) I'm very happy with the final results both taste great I still have 4litre pure juice left in freezer, so I can make more jelly when needed, and also ended up drying a good lot of the rowan berries as well All in all very pleased with the harvest and final products cheers I use the same method on brussel sprouts, if harvested in summer/fall, before we have had a few frost nights. I always toss them in the freezer over night to sweeten them before use
  6. Hi again Hunter Pehrson Here is 2 links on the matter, you will see that the "ideal" varies a lot, depending on fish species tolerance to ph swings https://thefishsite.com/articles/water-quality-a-priority-for-successful-aquaculture https://www.dpi.nsw.gov.au/fishing/aquaculture/publications/water-quality-management/monitoring-alkalinity-and-hardness I just uploaded a pdf on your Q to the download section as well, since links seems to have a limited shelf life Keep in mind that fish husbandry is just the same in aquaponics, as it is in aquaculture cheers

    Alkalinity and Hardness in Production Ponds
  8. Hi Hunterpehrson Welcome to APN/HQ To answer your Q on alkalinity, I find it easier to point you towards a thread/post and a APN article where the complexity are pretty well explained IMO Quote : Here are the most common scenarios you will encounter that require adjustments: Declining pH - Generally speaking, you will want to maintain your cycled system pH around 6.8-7.2. If it falls below this range, the nitrifying bacteria will be adversely impacted. You need to add a base. There are commercially available products for this, but you can also use relatively common chemical salts like sodium bicarbonate, calcium bicarbonate, potassium bicarbonate, calcium hydroxide, calcium chloride and many others. Specific recommendations are beyond the scope of this article, but will be featured in a later article related to maintaining pH levels....................... cut/paste from this article : I recommend you read all the answers in the post and the full article cheers Edit: I'll add this link here as well: cheers
  9. Hi Mohamed Welcome to APN/HQ Sure you can use buckets, however the container you choose to use is not representing the main load, so I can't see how that will represent much of a weight reduction on a system ? The sand & water is what should be your main focus and/or concern regarding weight, and it is a really important point to be sure that the place you put it can handle the total load There is a few pictures of small "bucket size" systems in different threads/posts, @vkn have some nice ones in his trial thread IMO Here is one " EASY " You being from India I recommend reading the hole thread, let us know how you progress with however system you choose, good luck on the journey cheers
  10. Hi OneTree Welcome to APN/HQ Mine is fine as well, that is after the last forum upgrade cheers
  11. Hi I just had to harvest some rowan berries ( https://en.wikipedia.org/wiki/Rowan ) as the trees are really full of them around here, this year. They are really bitter and need to be frozen before use to release the sugar content . So I washed/cleaned them and got total 2,8kg berries for the freezer. Then I got on the net to find some recipes on how to make rowan jelly more to come cheers
  12. Hi Tam try this You can also use the search function (on the top right) just type in the word salt cheers
  13. Hi Tam When replying to posts, you do not use the report post button. That's for reporting spam abuse etc. , and can only be seen or read by moderators. I will copy your responses (in the 2 reports) to vkn & Toga here: Tam Submitted 5 hours ago Dear VKN, What temperature are you at? Do you have more turbidity due to the Silica dust? The temperature is 30 Celsius. I don't see turbidity from silicate dust so much. If it is not a lot, once essential microbes are established, the fish deaths rarely happen. What have you done to jump start the nitrification process? This picture show the way I used to raise bacteria. I use feed as source of ammoniac, bacteria I add in flour form. I add fish after nitrogen cycle is ok (nitrite is slow down 0.1; nitrate has increased more than 40 mg/l) on 7-Aug, Thank for your advice! Tam Submitted 4 hours ago Dear Toga, Thank for your help, Tomorrow I will follow your instruction, I will change water, add salt batch for cure fish, stop feeding, As I post to reply report to Vkn, I had create the nitrogen cycle before adding fish on 7-Aug, I willing to hear your help on my beginning small system, Thank Tam cheers
  14. Hi Tam Welcome to APN/HQ Hopefully @vkn @Aufin or some other member with hands on IAVS experience will see your post and chime in cheers
  15. Hi Gary Yes I'm still in to quail, but I have to "refresh" the blood lines so I'm down to a handful right now. I plan to hatch out a new badge in september cheers
  16. Hi richinC Welcome to APN/HQ Hopefully @bcotton will chime in, he has some experience with the species in Q cheers
  17. Hi Amazing journey https://polarresearch.net/index.php/polar/article/view/3512 Quote: The fox was under a year old when she set off west in search of food, reaching Greenland just 21 days later - a journey of 1,512 km - before trudging forward on the second leg of her trek. She was tracked to Canada's Ellesmere Island, nearly 2,000 km further, just 76 days after leaving Svalbard. https://www.bbc.com/news/blogs-news-from-elsewhere-48824181 cheers

    Hi Wenger Welcome to APN/HQ I wouldn't worry at all cheers
  19. Hi My sister plan a family gathering mid July, she asked about the possibility of me fixing some crabs for the occasion. So I did a test/traping (first go this season) with 5 traps for 2 days. I got 90 and they where nice cheers
  20. If you live close to the sea you can make it DIY cheers
  21. Hi Ricardo Many members use maxicrop and it's safe to use, see link https://maxicrop.com You will find numerous discussion on how to use it here on APN/HQ by using the search function. I got 163 hits , here http://aquaponicsnation.com/forums/search/?type=all&q=maxicrop cheers
  22. Hi again Ricardo You'w got me a little confused with the above statement ? Any/all aquaponic systems, contain a hydroponic system of some sort(s) That is Aquaponics pr definition " Aquaculture + hydroponic ". If you by "hybrid" mean that they can be run separately from each other, that is a good thing and not uncommon. That gives you the opportunity, to easy isolate the fish/plant -sides, from each other for treatment if/when needed. If you by "hybrid" mean multiple type growing systems, that is fairly common at hobby level and you'll find many member systems of that kind posted here on APN/HQ. As for lack of plant nutrients from the fish waste, please read the full fact sheet (pdf/link) This quote is taken from the aquaponics factsheet : http://www.aquaponic.com.au/Fish to plant ratios.pdf The Rakocy approach was determined by taking a look at how aquaponic systems work. Rakocy quickly determined that fish feed contains the essential mixture of nutrients required for the healthy and maximised growth of the fish, but that fish have different nutrient requirements to plants. The key factors in this difference are: Fish do not require any where near the level of two main nutrients that plants do (Potassium – K, and Calcium – Ca). Fish metabolism relies on large proportions or quantities of protein that fish utilise via metabolic pathways that convert this protein into energy. The major waste products after this metabolism are Nitrogen (N) and Phosphorous (P). Fish do not need the same level of other key macro-nutrients that plants do (Sulphur – S, Magnesium – Mg and Iron – Fe, to name a few). The outcome, and what Rakocy determined, is that plants require a different mixture of nutrients than what fish feed contains and therefore, a method was required to account for this. cheers
  23. Hi Shrike Welcome to APN/HQ Your suggestion has been discussed in various threads earlier, like this: cheers
  24. @kellenw Hi Kellen The forum is loading really slow, and have for the last few weeks. It takes 22-25 seconds to load a new page/search, this does not encourage members to read, post, or respond in any way. Comparing with the other ap-forums where the same is done in 0,002-0,003 seconds about X 10.000 faster, than APN at the moment. I hope you find time to fix it cheers
