Tank overheating Thank You

[Zen Reef]

Mike, this happened to me last summer. Dropping to water in the tank will mean you have to watch the salinity. I bought a case of bottled water and froze them. I dropped several bottles (unopened) in at a time when needed. While the initial bottles were freezing, I used ziplocks filled with ice. I just grabbed a few 20lb bags of ice and put them in a cooler. Made sense to me at the time and allowed me to keep my tank cool without having to worry about salinity. Hth.
