My tank is already running hot. 87.6 at 530 this morning, The heater is unpluged. I turned off the power heads, and kept the lights off today hoping that would help. but at 4 this afternoon It was only down to 84.9. I have reuseable ice packs that I put in there but the fish don't like them. I'm afraid it might stress them out to much. And it is not that the heat is to high in my apt. I don't even have the heat on. Hasn't been on all year. If it is this warm already what about when it really warms up. I thought about a chiller.do they very small probe things, just like a heater but it is a cooler? I need to probley try to get that other 75 gal set up within the next week or two. I would like to try to get over flows or just get it drilled. Any suggestions on which method would be better. If I get it drilled, any suggestion on who does a good job at a fair price. The skimmer I was going to get got cancelled. The guy I was going to buy it from emailed me today. His cracked so he is going to have to keep it. I was going to get a GSA2 or 3. Should I just keep looking for one of those or is there a better solution. Thanks again.
