New member
hi i used to have a (1 ton 1 hp)ac connected to a heat exchanger on my fishtank...

this was about 5 years ago and it was a 350 gallon tank...

now i am setting up a 150 and still have the ac unit outside...

is the 1 ton way to large?

who makes a heat exchange unit to put in line plumbing and attach to the ac unit??

does anyone make a 1/2 hp outside unit???
