ggooden Posted December 12, 2012 Share Posted December 12, 2012 I have 2 48inch Marineland Reef Capable Led lights I was wandering were these sufficient light for a 90 gallon for polyps and shroom and some LPS Quote Link to comment Share on other sites More sharing options...
George Monnat Jr Posted December 12, 2012 Share Posted December 12, 2012 I have 2 48inch Marineland Reef Capable Led lights I was wandering were these sufficient light for a 90 gallon for polyps and shroom and some LPS Here's a chart I go by, provided by one of the other ARC members. You'll need to borrow or buy a PAR meter to test your setup. I have more information in my RC blog. Note: I'm not a marine biologist or coral expert (by any means), but I know optoelectronics.

ggooden Posted December 13, 2012 Author Share Posted December 13, 2012 does anybody have a par meter that would like a few dollars Quote Link to comment Share on other sites More sharing options...
Timfish Posted December 13, 2012 Share Posted December 13, 2012 I don't disagree with the rough guidelines George posted but for best success try to find corals that have grown under similar lighting conditions to what you have. For example I've had a Frogspawn colony do well with just 10 PAR and it would have to be carefully acclimated to 100 or 200 PAR. If I remember correctly the Marineland Reef Capable LED has charts showing the PAR readings and on shallow tanks may work fine but I suspect will be weak if used on a 90. Aquadome has some of ARC sponser BuildMyLED fixtures as well as some other LED fixtures if you look at some of your options. 1 Quote Link to comment Share on other sites More sharing options...
George Monnat Jr Posted December 13, 2012 Share Posted December 13, 2012 Timfish has a great point, all things need to be slowly acclimated as sudden bright light can shock and bleach them. Quote Link to comment Share on other sites More sharing options...
ggooden Posted December 13, 2012 Author Share Posted December 13, 2012 It say that the PAr is 64 at 24 so polyps and shroom no lps and I really wanted a Frogspawn but I have 2 so it should be more right Quote Link to comment Share on other sites More sharing options...
