I keep my place around 70-72 all year round and have no trouble keeping the tank temp stable with just air blown across the display top, nothing on the sump frag section so i don't think you'll have too many probs if you use halides - by halides i mean radiums because obviously they're the only ones worth running...


As Perc wisely suggested though, some testing might be in order and don't forget that the more you blow on the tank the more humidity is in the house so you need to allow for removing that or the house will fog up lol. In summer the aircon removes the moisture and in winter i leave a window open during the day when not home otherwise the windows fog up - unwanted humidity is not often thought of when planning a tank so best you're aware of that little reef keeping bonus now. :lmao:
Just so you know, the WP-25 i have running has no probs reaching across the 40" width of my tank when it ramps up to full throttle - it's quite a little beast and i'm still in shock that it does what it does for $70- plus shipping, will definitely be getting more. :thumbsup:
I use 3 x 39W ATI B+ and a KZ purple and there are small frags down near the front bottom that only receive direct light from 2 x B+ bulbs and color and growth is fine so i can't speak highly enough of the ATI B+ bulbs mate. I have no idea if the KZ purple is making any difference so i might throw all B+ bulbs on for a month or two to see if anything reacts color wise. Sorry i can't advise on T5's much as this is the first time i've used them - i will say they're the ducks guts when it comes to filling in those spots the halide misses due to shading and i'd recommend running a few with the halides if you go that route.
You've made 7 post without a pic Quintis, not pressuring you or anything just pointing that statistic out is all...........
