  1. The inverters are much less pricey but I'm not sure if one can make them automatic? http://www.jehmco.com/html/battery_inverters.html
  2. John, You may be right. I'm going to purchase one designed for fish tanks which even includes a fan for cooling. I'm also going to pick the brain of the seller to make sure all is well this time. I'm not sure where I got this link but something along the lines of the following: http://www.jehmco.com/html/battery_backup_system.html I'm fine if I'm home or awake if the power goes out as I have a DC pump I can hook up that can run the RBC. However what worries me is the reverse situation so that is why I will still push for an automatic backup.
  3. I checked and the original battery is 12 volts that came with the UPS. Well here's what the UPS says on it: Being electrically challenged I recognize a few things but there seems to be a lot of information. The pump says 65 watts 1.5 amps. The UPS is fried I believe. As you can see in the picture the bottom is warped from the heat. At least I didn't pay anything for it and didn't start a house fire! Can you make a judgment by the information given? The 12 volt deep cycle battery says Max cranking amps @ 32 F. 500; Amp hours 75; Cold Cranking amps 405
  4. Not even the RBC itself minus the frame as it is too large. But that is a good thought. I've thought if I build another one i could make it smaller and rotate it in a 55 gallon drum cut in half lengthwise.
  5. Thanks KellenW for posting how to do this on a pond oriented website a while back! My electrician (my dad) is in Florida for the winter so I needed all the help I could get! It turns out I had a UPS unit laying around the house and the only thing wrong with it was a bad battery. (This is one of those things we use to back up our computers in case of a power outage). I wanted more battery than what came with the UPS anyway hence the deep cycle trolling motor. I added male spade connectors to one end to connect to the wiring in the UPS where the small bad battery was, and then female battery post leads to the other end to connect it to a deep cycle trolling motor battery. Here's the set up on a shelf I built connected to a the battery underneath it. (There is more clearance around the unit than it appears for air cooling). The recirculating aquaculture system is on the other side of the wall, which is nice as all the power and plug ins are separated by a wall. The AC pump that runs the rotating biofilter by dropping water on the paddles and moves water out of the clarifier is plugged into the UPS. I purposely cut the power to that outlet at the breaker box, and the UPS did it's job and automatically cut over to the battery. Constructive criticism and suggestions welcome, especially from those here that know a lot more than I do!
  6. Well that's something to consider for the future if I believe it's necessary. As common and cheap as used PC's are I don't think it would be a problem to hook one up.
  7. Well the UPS must be doing a good job charging up the battery as I put the battery on a charger today expecting it to be down somewhat. In a few seconds the light turned green indicating the battery was fully charged. However tomorrow I'm going to run the pump on just DC (the battery) and see how long the battery will keep the pump running. I also want to see how long it takes the UPS to charge back up the battery, which will probably be a while as it's designed for a smaller gel type battery. At some point I will get a pulse charger if it appears the UPS is not up to the task.
  8. One more thing! I've been told by a couple of posters on another website I should hook up a pulse charger like this one as the UPS is designed to charge a small gel battery vs. the deep cycle I have hooked up now. Heck I didn't even know the UPS did any charging! I figured I'd have to take the battery off now and them and charge it! r http://www.amazon.com/dp/B001TQFB5I/ref=asc_df_B001TQFB5I992372?smid=ATVPDKIKX0DER&tag=nextag-auto-delta-20&linkCode=asn&creative=380341&creativeASIN=B001TQFB5I
  9. Yes it's an agitator hanging from the ceiling.
  10. The tank is galvanized metal but it's coated on the inside. I got it from a trout farm and it had been used before. Yes I've seen covers on biofilters. On the other hand the room usually stays pretty dark. However I'm sure I could come up with some kind of cover, especially since it would be in a separate tank. Any comments on gravity overflow to run water bact into the tank? How about the use of some kind of spray bar?
  11. I wasn't either. I saw it on a link you gave me. At least I think it was you? My dad who has worked with electricity for 21 years after he retired from the military, warned me to be careful about connecting a second battery. (I talked to him on the phone). He said if I did it wrong I'd get one 24 volt battery vs. just more reserve power which could cause some damage.
  12. Neal, Looks like once a year is the norm for other parts of the country too after talking to some other guys that raise them. Like I said I'm surprised there is no impetus to produce them more than once a year with all the demand. I went to the Keo website and they were shipping to Israel and Taiwan for God's sake. Perhaps there is a hurdle to multi cohort production with this hybrid?
  13. Are you sure a supplier doesn't have multiple cohorts by manipulating the photoperiod? I can't imagine someone can continously supply restaurants without multiple cohorts. I know grading will get one by a little, but not that much for a large scale commercial system. They are doing this now with yellow perch and bluegills and of course have been doing it with trout for some time along with triploids. The business I was talking about gets them delivered by truck even though it's several hundred miles. Edit: I apologize if it sounds like I'm questioning your knowledge on this. It's just I'm surprised they aren't producing multiple cohorts. After some reading up on the Internet I see why. The broodfish are apparently pond raised. Hard to manipulate the photoperiod outside!
  14. Welcome aboard! My dad retired as a Master Sergeant/ E-8 from the Army way back in 1973. Then he worked another 21 years as an I & R man for a telephone company. As a Green Beret during the Vietnam era It's amazing he's alive today. I'm sure you've had some serious involvement in a few places yourself in the last 20 years. I'm just getting started with an RAS myself, so I have a lot to learn there. However if you have any pond questions shoot away. (No pun intended) I've made every mistake in the book on ponds so I consider myself an expert now. Have you heard of a website known as Pond Boss? if not it's a great website for those with ponds.
  15. I have a PHD down the road that raises them in an RAS for the Chicago gourmet market. He gets them from a supplier down south but i believe he gets them more than once a year. Maybe your supplier isn't the same one?
  16. Ravnis gives outstanding info as usual although I beg to differ on a couple things. 1.) Redears can be pellet trained if you are patient, start out with live feed, progress to hydrated feed and then the dry stuff. However if you're going to use a fish in the sunfish family it's easier to just go with the bluegills. 2.) From my experience bluegills can by grown out to food size in a years time or even less if you keep water temps in the optimum range and use good broodstock. I also know a professor that does so in an RAS and can get them to a pound in 10 months. The problem with bluegills is hardly anyone has done selective breeding with them, and they are grown out outdoors w here several months of the year they don't even grow due to cold temps. My bluegill will reach food size in less than a year even though they are grown out outdoors. A dentist friend in Nebraska provided my broodstock, and he has been selectively breeding them for sometime as a hobby. I am just getting started with an RAS and am looking forward to what size I can get them in indoors in optimum temps. As far as the trout you could have them if you keep water temps 65 F. or below, but this can become problematic in the summer unless you want to pay a huge air conditioning bill and freeze out everyone in the house. You can also get a chiller which tend to be expensive. Another downside to trout is you will need more biofilter capacity to make up for the cooler less optimum temps for the bacteria.
  17. If you've got trout and bluegills in the same water somebody isn't in their optimum temp range for maximum growth and it sounds like the bluegills, no?
  18. From my limited experience disease is usually stress related and can be traced back to environmental stressors.
  19. No actually six pounds plus. That's only a three year old fish. It's too bad bass don't grow that fast. BTW I have just discovered my clarifer does an excellent job of removing iron particles. My iron filter isn't working well and when I refilled the tank the water was a a nasty brown. In 48 hours the water is crystal clear and most likely the iron was siphoned in and trapped under the netting. There isn't any on the bottom of the fish tank so it can't be from settling.
  20. Thanks for the kind words Iank. Actually if I continue with the trout it will probably be an RAS verse flow through. Much less water flow then and easier to treat. I'll leave you with my twin holding one of the browns I raised. We harvested by hook and line. He's an accountant and wasn't that thrilled with catching the fish. He said it didn't do much for him. Yes Kellerw I told him to hold the fish like Bruce Condello. (It's an inside joke. If anyone wants to know we'll tell you). Cheers Cecil
  21. Wow I didn't know that. I'd love to get some of their stuff cheap!
  22. That would work IanK but I was running 60,000 gallons of borehole water through the pond a day! Here's a Russian invention for removing high amounts of iron from large quantities of water. It says, "The system itself has no pumps, no compressors, and no electrical, rotating or moving parts - virtually nothing to go wrong. Backwash is hydro-automatic - i.e. is controlled by levels of water in the system. Only 0.8 to 1.6 % of daily water flow is used for backwashing - depending on the initial levels of iron." http://www.deferum.com/what-is-deferum.html
  23. I was told by a professor that I could get rid of the iron by running it through a ditch with a lot of grass, but of course it would also get too warm in the summer for the trout pond.
  24. In my trout pond I did believe something else was up taking iron more than could account for just settling. I have to wonder if the extensive Chara and/or iron bacteria was doing that. Came in at about 2.5 mg/l. Early in the year before the water got into the upper 50's F. (14 to 16 C.) the pond would read about 1.5 mg/l but later in the summer it would hang around 0.5 mg/l. That led me to believe that was because the Chara was more extensive later in the year and or the iron bacteria was more active in the warmer water. Could be. I had trout farmer tell me that Chara loves well (borehole) water.
  25. Actually you may not be far off. I seem to remember something about using electricity to collect clump iron based on electron charges. The easiest way to remove iron in the water is to aerate it vigorously by several different means (it only takes .15 mg.l of oxygen) which causes the iron to precipitate in what was otherwise crystal clear water. You can either then filter out the iron, run it over a surface it will adhere to, or allow it to settle. For some reason my iron takes much longer to settle out than the text books say. And with the 45 gpm I was flowing into the trout pond, it wasn't feasible. Too much water and it would have warmed outside during the summer as the iron was settling so it wasn't practical. If I ran it into a pond and allowed it to flow into another it did drop to about 0.5 mg/l but the water would warm about 10 degrees by the time it got to the second pond.
