"I am a biology professor at a community college. Our science club has been experimenting with aquaponics. I have eaten cucumbers, kale, chard, peppers, and collards from this small system. (under member systems see small system with $)"
"I did a couple small (25 gallons or so; 300 gallon system) water changes early on. I also added a product to "bind" the nitrite and block it's toxicity. I have not found any product that removes nitrite, only -ate, ammonia,…"
"Not sure what kind of trouble they were having...or why...but DWC is one of the easiest, oldest, most well suited for commercial scale production of water culture greens and lettuce on the planet.(Both AP and hydro)...
For "speed" and…"
"LOL, somehow autocorrect turned "bell siphon" in iPhone? Wow
Looking into the bell siphon is how I have been monitoring, however, there is one grobed that is taking, imo, too long to fill. I will try to get them timing as Paul suggested…"

"I have 4) 12cu ft grow beds (4'x3') and am about to add an IBC GB to it. I am also running it as a CHOP2 system. I was running as a CHOP system but found that I was pushing too much water through my FT. My GB's drain at differ times…"
"hhhhmmmmm Interesting information Vlad. Deep water may be better. Then again perhaps the grow towers would be even better as I understand that they also act as a bio filter like that of the media beds. I'm just not as versed in the towers yet.…"
"FYI: Aqualibrium system (http://aqualibrium.com/)I got one via a friend who supported their Kickstarter. I'm glad I didn't pay for it.
Its pretty, and it does work/function.
However, it is obviously designed by people who didn't try…"
"If you hadn't, you should probably do a water change of some non-tiny amount.
You added a pretty large volume of fish with the catfish. Even if you weren't feeding them much, they're still putting out waste since they were eating…"
"I did do the media test for lime. have more plants in seeds under the stone just waiting for it to come up.
Did you see my siphon time? 6 minutes 49 seconds fill time and 1 minute 55 seconds drain....what you think?"
"I wound up putting 2" Styrofoam around the sump. I can only assume it helps. I boxed in my GBs from the ground up with 1" foam and covered them with a mylar low tunnel with the grow lights inside for heat at night. I only heat the GH…"
"Deborah, I have 35 1/2 barrel beds that operate on their own timing. I have found that all I have to do is look into the siphons each day to check the water levels. If the water is somewhere in between the top and bottom of the drain, it tells me…"
