Well I'm happy to report that after running a small Honeywell Forced Air type fan(cost $25) from Home Depot, it has helped out my reef BIGTIME
It's now 2pm and peak temperature is 94 outside in the shade using a good old mercury thermometer
Today I removed the lid on my 4gl sump, setup the fan, and have had it on all day, cooling the water surface of the sump. I am happy to report that after yesterday's high of 86 I am now sitting at a stable 81. That's a whole lot better in my books. As for evaporation, I just brought my sump back up to it's normal level using 1 litre(or a 1000ml
) of bottled springwater. So I guess that giving my tank a bottle a day is not too bad
Goodluck with the heat everyone!
cheers, Rich
