  1. Thanks for the link. Interesting fish that can reach a good size and is good to eat.
  2. If you don't mind me asking what kind of catfish do you use in the land down under? Is it a native catfish?
  3. I never thought I'd be happy to see bacteria growing but I am! Imagine that, excited to see that bacteria is multiplying! Yes I am a newbie with it comes to an RAS! Anyway after several weeks I'm finally seeing nitrites show up in my water testing, which means there is some nitrosomonas bacteria working on the ammonia. (.25 mg/l) I also see some color in the nitrate test but not enough yet to show 1.0 mg/l. I goofed by initially adding ammonia with a surfactant and had to drain and start all over. One thing I've had going against me is the it's in my basement and the water has a hard time getting above 65 F. (18.3 C.) I've been adding some starter fish feed mixed with hot water to thoroughly dissolve it, and then adding it to the tank once a day. And another natural ammonia product that is a personal recipe if you know what I mean. The only thing I don't like about adding the feed is discolors the water. It's very high in protein though, I believe at least 50 percent.
  4. O.k no one got excited. I need to get a life.
  5. From reading Gary's book I see you folks in the land down under collect rainfall in barrels from your downspouts if I remember right. Makes a lot of sense, but are there any concerns about contaminents from shingles or certain types of roofs? What about the rain itself? Any concern about pollutants or low PH? BTW I found this site. http://www.gardenwatersaver.com/2.html Kind of a neat piece of hardware the collects rain in a downspout and routes it to a barrel. And when the barrel if full back pressure routes the rest down the downspout. Probably nothing new for those who collect rainfall but I thought it was pretty clever.
  6. Thank you Gentlemen. Very Interesting.
  7. You mean the bird **** isn't good fertilizer?
  8. In regards to my thread where I was singing the praises of the UPS I hooked up to a deep cycle battery, to route power from a battery to a pump I am using, in case of a power outage, I need to qualify that. As a test I purposely cut the AC power and allowed the UPS to kick over to the deep cycle battery. I came back in less than a hour and the pump was not running and something smelled hot. The UPS was beeping continuously and very hot to the touch. Three possibilities: 1.) The UPS is to small to handle the deep cycle battery 2.) The UPS was damaged in a power surge previously, which is why we replaced it on the computer vs. just a bad battery. 3.) There wasn't enough airflow around the UPS, which is not directly on the wall but close. 4.) Something is wrong with the deep cycle battery itself. I'm leaning toward number 1. I don't believe it's the battery as the charger I have didn't take very long to charge it back up again, and showed it fully charged before the test. And the UPS works fine for a short while, but gets hot until it shuts down. Thoughts from you sparkies?
  9. 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
  10. 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.
  11. 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
  12. 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.
  13. 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!
  14. 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.
  15. 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.
  16. 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
  17. Yes it's an agitator hanging from the ceiling.
  18. 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?
  19. 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.
  20. 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?
  21. 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!
  22. 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.
  23. 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?
  24. 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.
  25. 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?
