smallreef January 3, 2013 Share January 3, 2013 I'm getting in on the group buy for evergrow...and was thinking about the IT 2040 fixture...but with talking to Jake the other day wondering if 1 fixture will be enoug to cover my 50g tank...its 3 ft wide by 2ft deep Should i get 120 optics for the outside sides to make sure i have coverage? Or just get 2 D120s? Link to comment Share on other sites More sharing options...
Jim January 3, 2013 Share January 3, 2013 I'm going with 2 D120's for a 40 breeder. Depending on the coverage you want I don't think 1 is enough for a 3' footprint. Link to comment Share on other sites More sharing options...
ridetheducati January 3, 2013 Share January 3, 2013 Get two units. Link to comment Share on other sites More sharing options...
Coral Hind January 3, 2013 Share January 3, 2013 What types of corals are you keeping? If you did wider optics on the outside you could keep less light demanding corals on the sides of the tank and just use one fixture. If you think it isn't enough just grab another on the next group buy. If funding isn't an issue then go for two units. Link to comment Share on other sites More sharing options...
dbartco January 3, 2013 Share January 3, 2013 I tried one over a 30" tank, only about 8' off the water, and it was not enough spread. I went with 2 in a "T" formation (adjusted the rocks below) because 2 did not fit end to end for a 30" tank. Need to take some photos... Link to comment Share on other sites More sharing options...
YHSublime January 3, 2013 Share January 3, 2013 Also interested in this buy, will be following for an answer! Link to comment Share on other sites More sharing options...
smallreef January 3, 2013 Author Share January 3, 2013 Im going to go with 2 D120s instead of the 1IT2040... will end up at about the same cost... and when I end up getting a controller all will be fine, lol Link to comment Share on other sites More sharing options...
Rosco's Reefs January 3, 2013 Share January 3, 2013 I was under the impression these lights cannot be managed by a controller (other than on and off.) Thx Link to comment Share on other sites More sharing options...
zygote2k January 3, 2013 Share January 3, 2013 D120's not controllable. IT2040 Controllable with manufacturer controller. If growing LPS/softies only 1 light per 3' square or less. If growing SPS, 1 or 2 per 3' square. 1 is fine for most applications. Link to comment Share on other sites More sharing options...
smallreef January 3, 2013 Author Share January 3, 2013 I was under the impression these lights cannot be managed by a controller (other than on and off.) Thx Thats actually all I want... I have a stupid corallife powerstrip unit now that is SUPPOSED to control the on and off ,,, but alas.. it sucks.. so its more like me turning them on every morning.. and some days they get no daylight :( when I work a 12 hours day...
