For those of you who read my intro, I am brand new to this! I would like to raise about 20-30 tilapia and a variety of warm loving veggies (Is it possible to do a tomato species?). I am in a cooler climate for winter months (Connecticut), so I know I will have to bury the tank to help with warmth and am getting an immersible heater. My ultimate questions are:

What size tank do I need for fish?
What size grow bed to make it balanced?
What size pump would be sufficient to pump the water up to the grow bed?

I would ultimately like a build a Constant Ebb and Flow system, having the water pump up to the grow bed and drain back into the fish tank through means of gravity. I am unclear of how to actually set up the pump and pipes as well. Any suggestions would be super appreciated! Please take this novice and mold her into a sufficient Aquaponics operator!

Thanks all
