well my tank is fluctuating by over five degrees F per day, with two fans in the canopy. they are producing a fair bit of air flow, as the wood in the canopy is only slightly warm, the back of the reflectors are cool enough to touch - however my eurobracing is much hotter that i would have expected, obviously because of the light blazing down on them. i have to add more venting, because if i close the canopy lid and door, the fans actually slow down, as they are pushing more air in than is escaping i expect. so i am going to add two more fans. the question is, should i put them below my other two, meaning i'll have four on one end? should i put them on the other side, blowing out? the easiest thing would be to actually put them blowing down from the canopy lid, and i expect this would cool the eurobracing the most... any opinions?
