would it be a good idea to funnel my water cooling into my fish tank as a means of heating my fish tank too? lol.. It's a big 20 gallon pool of water.. Wouldn't it make sense to and just put a submergable pump in it to pump the water up and through the system? It might get slimmy but if the water moves through the hosing at a decent rate then algee shouldn't really grow.. Tell me what you guys think.. I brought it up to my roommate and he thought it was a pretty good idea.. If only school would allow fish tanks!
