I have a year round 70-72 degree spring/artesian well that runs naturally at 5 gpm...7200 gallons a day..
It is what keeps my pond full all year even in drought but I don't need the extra water in the winter at all.. The water quality is excellent according to A&M for any use..

I wonder if that could help me cut down on cost of over-wintering some tilapia here in SE Texas?
I sure want them in my ponds..

I might try it this sept/oct if I can find the fish..

Seems like a great fish on many different levels.. I also enjoy the mild taste of the fish as well.. They really seems to suck up any type of spices you add before cooking and are not a very fishy smelling fish at all.

I was already going to build a 4x8x4 (aprox 1000 gallons) fiber glass tank for another project... If I insulated the tank and built a small greehouse Maybe I could try some Tilapia instead?

I now have more questions for Meadowlark on my visit..

I wonder how many Tilapia I could raise with 7200 gallons of 70-72 degree water a day...

I would think it would help heat, flush and aerate the tank or maybe tanks?

Sounds like a fun project anyway..
I always had aquariums as a youngster and the fish did very well and multiplied..
