Well i was just about to post a message like this one. Im haveing the same problem I have a canopy over my tank its total enclosed but the back of it.The tank is getting to warm with mh
running. Its a 75 gallon tank with a 30 gallon sump. I have no fans in it yet.. my ph
has been running a little low to(around 8.0). Which i think is caused by not enough not enough air exchange.( i was told this by other reefers on this site) I can send you a picture of the tank if you send me your e-mail address in a private message. Im looking for suggestions on what i should install for fans. And where to install .Should fans blow on lights or on water?? Should one fan bring in fresh air and the other blow it out?
I have two 250 watt 10k mh
.And two 55 watt Atanics 03
. I run my lights from 9am to 9pm. I also try to keep my tank temp around 83 degrees. With one mh
running and the 55watt. My tank temp will rise to 85-86 degrees by 5 pm .But it does not go higher than that. Thats why i have only running one mh
. I am looking for any sugestions
