I have a 100 Gallon tank and Platinum 39 sump. I measured about 22 gallons of water in the sump but didn't get an accurate tally of the water in the tank after aquascape / sand...so I'm assuming it's around 100 - 115 gallons total. Temps recorded on Apex.
Based on that I bought the 300W heater with controller from BRS and set it to 77degrees. It typically kicks on around 76.3 and off around 78.4 (I understand they have a tolerance...and I'm assuming those temps aren't that far from 77 so no harm done).
The issue is that it takes that heater about three hours to bring the temp up. so it's heating 2 degrees in about three hours.
Is this ok? seems like it's running for quite a while.
I'm thinking of buying a 500W with controller and putting the 300W away as a "backup" when / if needed...or perhaps leaving it in and setting the apex to turn on that outlet if the temp drops to a certain point (primary 500W failure).
