Just wondering as i setup my sump/refugium,
ive noticed that many people have said that it is a good place to put peices of equiptment that you dont want to see inc heater.
i will have two heaters in my total setup, 325lt main tank and an 80ltr(apprx) refugium/sump, now can i have both the heaters in the sump or will it make the water in the main tank to cool or do you need to compensate for cooling of the water on the way to the main tank by haveing a higher temp setting on the heaters in the refugium??
Sorry if some of these questions are seem trivial to some of you
