Hi All!
Very interesting and informative post! Last year I started the project of tearing down my 75 gallon and turning it into a sump/fuge for a new 120 gallon. I have just finished the project of setting up my new system. I could not figure out why this tank was running so much hotter then the old but from bangs post I am assuming it is because this tank has ALOT more waterflow (and alot more pumps)!!
My tank just recently cycled
and I have the same question as amphicar77. I have a reefkeeper2 controller and during my cycle the tank was running at around 83 my metal halides would never come on as the reefkeeper was set to cut them off below this temp. My target temp is 78 and my heater NEVER came on. On occasion during the cycle I turned the MH's on manually to see what would happen to the temp and the tank would get up to around 86 (that was with the fan in the hood which is always running on)
My TradeWind chiller arrived yesterday and it seems my chiller and heater are fighting a war.
I have the reefkeeper set to heat the tank up to 78 degrees and the chiller comes on at 79.3 and off at 78.1 as soon as the chiller goes off the heater goes on and as soon as the heater goes off the chiller goes on.
I know that I can solve this by changing the tempatures to be a little further apart but I thought that too much temp fluctuation was a bad thing!!! Can anyone give advise for some good settings that will end this war yet not cause to much water fluctuation???
