Now that winter is over and spring/summer has hit... I noticed my tank is increasing in temperature. During the winter I kept the house around 65 to 70 degrees. The tank was between 83.7 and 84.3 degrees. Now with the temp in the house around 75-80 degrees, I noticed my tank is at 88-90 degrees.

I have a 6k gph submersible in my sump that produces heat, but it looks like it's staying around 88-90 degrees. Is that too hot for BDs. They seem to be doing ok, but I don't want to come home to dead rays because I cooked them.

What is the warmest your rays have been in a tank?
 
Just open your lids your temp will drop. 90 degrees is too much IMO I mean I wouldn't keep it past 85 but thats just me. I keep mine at 78-82 depending on the season lol
 
It's more long term exposure. My male bred my female once on the first scorching day of the spring that put tank temp between 29-30 C, they must have been happy enough in there. Their temp fluctuates in the wild too, rainy season, drought, etc. I would say not to worry for a couple days or whatever but if it becomes long term, you may need to freeze ice jugs and leave em in your tank for a bit.

I took the lid off of my sump to try and cool things a bit but didn't work. I could remove the lids but I think it will make the living/dining room a sauna lol. I thought about getting a chiller, but for now I have kept it steady by turning on the AC, but that is running me about $400 a month lol.

Thank you for the information davenmandy. I was also thinking of doing more water changes than what I have been doing. After a 20/30% water change, I can get the temp down to about 81 degrees, but eventually it will go back up.
 
Might have to resort to 1 or 2 frozen bottles of water. Use two in the tank and have another two in the fridge on stand by for the next day. Just keep that rotation going.

LOL, the rays are in my 600 gallon tank... I would need a couple of gallon milk jugs with frozen water to help out with the tank... this is going to be a pain in my arse...

I accidently raised my small tanks temp to 90 and one of my bigger cichlids took a dive lol I didn't notice it I ran and got some Ice and put it in a ziplock and 10 minutes later he was fine. Hes old cichlid and was scared I lost him. Temps went from 82 to 90 real quick lol. I dialed in my water change wrong.
