My breeding Blue Tilapia have given me an abundance of babies. So much so, that I now keep them in separate tanks...which I am very much needing the space of to winter a portion of the babies over the winter months. (They grow so fast!) I currently…See More
"Hi Jeremiah, I'm not saying that Jeff's sump will float, but neither am I saying that it will not. Only that if certain conditions conspire to align, it can. I've seen a buried IBC sump do that. Two of them actually. The one sump had…"
"Hey Jeff, with the plastic walls of an IBC provide enough insulation to negate most of the cooling effects of the ground unless it was really moist.
If you took a freezer and cut a hole in the top (never the sides!) to put your pump down through,…"
"I keep reading about folks in AZ. that have problems cooling water in the summer. I have to wonder if just putting an IBC in the ground would help a lot with that, absorbing the cool ground temperature. Using an insulated refrigerator in the…"
"Hey Vlad, I'm still not sure that would be an issue for Jeff, assuming the water doesn't come up above the water level in his tanks. Even if it did, would a little shifting break anything in a plastic tank with a submersible…"
"Aquaponics is hydroponics with fish. That's the only real difference. Nutrients are supplied for the most part by fish waste instead of additives. If you'll visit Bright Agrotech on You Tube you'll get all the info you need about both…"
"Hi Alex. This post said no lants or fish so why would you change out your water at this time? I understand the adding of potassium bicarbonate to help stabilize the PH. I must be missing the picture here. Can you please explain."
"No you don't need a sump. a sump is helpful to help maintain the water level in the FT. As long as your grow beds don't draw down your FT to much, you should be all set. I was always told to cycle all my FT water at least once every hour."
"Hi guys, remember Archimedes of Syracuse ...that guy who told us that when our 50 gallon grow bed is filled with media (rocks, LECA, whatever) that it will no longer hold 50 gallons of water?
That same Principle of his, so aptly laid out over 2,200…"
"Jeff, you probably didn't intend to, but you just blew my mind.
First the issue you asked about: yes, spray foam would push back against the walls of your IBC if it was empty. There's no reason not to fill it first though, is there?
