I've gone through three impellers in less than a year at $40 each so that doesn't work for me. One impeller failure I'll take the blame for due to gravel intake but two is still too many.I installed…Continue
Can you tell me whether it is a hazard in any way to use steel rebar for stakes in a grow bed? I have a supply on hand and would like to use it, if feasible. I could also drive them in the ground…Continue
"Could be cutworms
(1) Shine at night and kill them by hand. This is my preferred method. Be persistent. The key is finally being there when the cutworm is feeding.
(2) Flood the bed to drive them to the surface. Feed…"
"If well water PH is 7 then how did your system water go from 6 to 8 or 7 to 8 (you wrote it both ways)? My answer is, it didn't. PH in aquaponics goes down, not up.

"It's a big subject and there is a lot of material archived on this site - participation has died down here and moved to facebook, or so I've heard. Take a look at Smoky Mountain Aquaponics - Jim Fish is in Tennessee. He may…"
"O2 is probably OK or they would all be dead.
If it's not nitrite, then you might want to read up on tilapia virus that is affecting some commercial systems. I'll see what I can find.
Have you introduced fish recently?"
"Yes, I'm all for growing good food. I don't know of a commercial fish food that might raise Omega 3 and I also don't know of anything I can produce at home that will raise Omega 3 levels in fish. If anyone does know,…"

Cycling as of 10/26/11. Bluegill stocked 12/2011. Interested in food quality and safety, permaculture. Gardener for many years, fisherman. As system matures, looking forward to comparisons between ground garden and aquaponics. 2014 fish stocking - bluegill, one largemouth bass, one catfish. August 2015 stocked tilapia. Tilapia grew rapidly and survived the winter but didn't feed for 2 1/2 months.
Sorry I did not see your post. I am heating my tank water to 75 degrees. The heater runs for a little while in the early dawn hours. I'm hoping to keep the tilapia growing through the winter. Will see if warm roots helps too.
Hi George, thanks, glad you like the system. This is my first time at aquaponics, and I am really happy with the results. We fired the system up for the first time December 12th 2011, and have harvested a lot of produce already, and have had a few fish dinners.
You can get a pot still for just distillation, living in florida you probably dont need the heat for a greenhouse. Look up Rainier Distillers on the internet. He built the distillation component for my stove. He builds all kinds of stills and can fix you up.
Sometimes the bulkhead fitting isn't tightened up all the way when you get it. Usually you just need to give the nut a slight tighten up. But you might want to make sure there is no grit between the tank wall and the gasket or the gasket and the flange of the bulkhead fitting on the inside of the tank. Make sure it's all clean and then tighten it up again.
