It's very subjective whether to use fan for FO tank, advise to maintain the temperature not more than 30 degree. Some reefers might have other opinions
No problem CM, Just finished the out flow piping and now planning careful for my in-flow piping to my main tank. I think yr is a smaller version,m i right?
I agree with spidy to be more specific. there are thousands and one reason on why this and why that. Maybe u could tell us some historic data abt yr tank
