Hello Everyone. I have aquaponics systems that I've built in Palm Harbor, Florida. My systems are pellet media type growbeds that pour out into a sump tank or fish tank. My fish tanks are always of the over-flow variety which empty out into a sump tank where I keep the pumps. I have a IBC tote as my sump tank and it's three feet in the ground, leaving a little less then 12 inches of tank sticking out of the ground. I would like to put freshwater prawns and or clams into my sump tanks and I was wondering if anyone had any input on this. I'm concerned about the prawns and the pumps. All of my pumps will be Danner Pond Masters. Any input would be greatly appreciated.
