Ca above 500. Always been like that. Kh 7-8 salinity around 1.025. How do I keep my water temp more stable without a chiller?



Lol ill let him know haha

Some people float frozen tank water in the sump instead of ATO for cooling off during this heat wave, if that's what you're trying to do.

Have a heater in the sump, and a fan on it as well. It's difficult without a controller, but if you have a controller - set the heater on when the temp dips to 78F and fan turn on if it hits 80.1F and off at 79F

Yes, it looks bleached which certainly can happen with over heating. Try running lights at night when it's cooler, frozen water bottles as suggested, fan across sump or surface of tank. Ca is a bit high, not sure how it got there, but I'd aim for under 440 max. Alk looks fine. Salinity is fine, so that does point to heat as the issue.
