I've found expanded shale is not as readily (locally) available in most area and paying shipping is out of the question. I used expanded clay with no problems and t lower cost I used lava rock in the lower half of my second bed. I took out the larger pieces to get more surface area.

OK been combing the web trying to find expanded shale here in Phoenix area? Not having much luck. SO a shout out to you all. Anyone know who might sell this stuff here in the Valley? Oh BTW hi all been off the forms for a few years due to a Motorcycle wreck. But auqaponics been running good for a bout 3-4 years now. Just lost all my fish on the Monday night storm due to power outage. But Hey, Just pull some of the babies out and feed them.

I have one rock bed finally had to clean it out after about 3.5 years. I grew nothing but tomatoes in and the roots finally goober up the tank and had to wash the BA-Zillion tiny roots to keep it from plugging up the Bell siphon.

Hey folks; a health problem hast cropped up forcing me at least for awhile to shut my  sytem down.

I have about 75 fish mostly Tilapia about a year old and several Red Comet Gold Fish.

If you have room in your tank and would like some fish please call Bob Rowe @ 602-799-7208.

The past week was rough on my system too.  I had 10 goldfish and went away for 10 days, had someone feed the fish every few days.  I'm down to 2 now.  Ammonia at .25ppm (even with the dead fish in the system), nitrites and nitrates at 0, and pH is around 7.4 which shouldn't be too bad.

If I had to guess, it's low oxygenation.  Store bought air pumps tend to not work long outside so I don't bother with external oxygenation outside of the water return from the grow beds auto-siphon,  Water temps were about 98 when I tested at 5:30PM, had to be hotter during the day (I don't keep the grow beds or FT shaded right now, going to move the system at some point)..  Do they sell O2 test kits at pet stores / aquarium shops locally?

Any newbies out there looking to build your own system? I have got everything you need and more.

I lost 2 plecos at at different times i a 45 gallon aquarium with 25 Tilapia fingerlings. When I say lost I mean they disappeared. I assumed the Tilapia ate them. I have 4 separate FTs from 45 gallon to 275 gallons and don't seem to have any fish loss problems no matter how bad the water seems to get.Sure I loose a fingerling from time to time but when you're talking 1200 fish it's not like there's a problem.

John: I wonder. Have any of your neighbors sprayed their yards or anything, that the wind might have carried it over into your tank? I always worry about things like that....

Robert, so sorry to hear about 'the disaster' - it always seems it is something, isnt' it? A few days ago, I realized I hadn't heard the bell kick in, and sure nuff, when I checked, the pump wasn't pumping. Dread...I took it apart, and cleaned out all the little obnoxious snails inside, and voila! full pump ahead. Went out and got my loaches to b e on duty and snail patrol, hopefully that won't happen. But if I had not been outside and notice this, the plants would likely all have died, and the fish would have gotten poisoned. Gosh. It is always something....
