wingsfan Posted February 6, 2004 Share Posted February 6, 2004 I picked up a jbj retro 4x65 that I plan to use over my 20 long. A few people have told me this might be too much light and I might bleach some of the corals I put in it. Can anybody give me any advise on this or have an opinion they wish to share? Link to comment
~_~ Posted February 6, 2004 Share Posted February 6, 2004 That lights fine... The only way they would bleach would be if you didn't acclimate them to the light. Link to comment
Jahkaya Posted February 6, 2004 Share Posted February 6, 2004 You can never have too much light for manby SPS and Clams. some Shrooms and sofites may not do as well directly under a 400w halide, but with PC's there is no worry. The problem being is that your tank is 30" and the 4x65 (most likely) is 48 inches. I am assuming that all 4 PC's are not side by side, but rather set lengthwise 2 and 2. If the whole fixture is only 24-30" long, than you should be fine. My Choice of bulbs for SPS and clams on a 30" fixture would be 2x10k 1x50/50 and 1 ACtinic. Link to comment
wingsfan Posted February 6, 2004 Author Share Posted February 6, 2004 It is 48 inches but I am going to cut it down to 30, the bulbs are 2-x10k and 2 actinics. Link to comment
Jahkaya Posted February 6, 2004 Share Posted February 6, 2004 Wings: If you split it in half you should be fine just alternating the bulbs. Not too much light by any means. Go For it!! Link to comment
hmpitags2006 Posted February 7, 2004 Share Posted February 7, 2004 you can never have too much light. you just need creative ways of counter reacting the consequences i.e. evaporation/heat Link to comment
