Stephen Posted January 2, 2013 Share Posted January 2, 2013 Are 24 3w LEDs enough to keep sps, clams and such? My current fixture is an diy led that I had original built for my 29 gallon. I haven't had the fixture up for more than a few days on my 40 gallon... Everything seems to be ok, I'm just concerned about the actual coverage that I am getting. The fixture itself is 6"x16" with 60 degree optics covering an area of 24"x24". Anyone have a par reader that I could borrow over the weekend?

Gig 'em @ NDstructible Posted January 3, 2013 Share Posted January 3, 2013 I've been able to keep SPS and clams under my DIY LED set up for over a year and a half now. I don't use any optics on mine because it's just a 10 gallon tank. What kind of LEDs and are they dimmable? Link to comment Share on other sites More sharing options...
Stephen Posted January 3, 2013 Author Share Posted January 3, 2013 I'm using Bridgelux 3 watt leds, with dimmers built in. Maybe the lights are powerful enough and I'm just programmed with the mentality of always wanting more power... How high off the water is your fixture Gig'em?

victoly Posted January 3, 2013 Share Posted January 3, 2013 That should be sufficient. I have 24 3w CREEs in a BC29 and I'm doing fine with a pretty good collection of SPS. Mine is mounted about an inch off of the water surface. Link to comment Share on other sites More sharing options...
Gig 'em @ NDstructible Posted January 4, 2013 Share Posted January 4, 2013 Mine is resting just about 2 inches above the surface Link to comment Share on other sites More sharing options...
Timfish Posted January 9, 2013 Share Posted January 9, 2013 I don't know if this helps but this T. squamosa is in a 150 gal system. It was under six T5s (3 39 & 3 54) but for the last 9 months the tank has had 48 3 watt LEDs (2 CW - 1 RB - 1 B) and has been doing fine. The clam is about 1 ft below the LEDs and counting the LEDs for 2' above it there's 24 LEDs. Link to comment Share on other sites More sharing options...

Timfish Posted February 27, 2013 Share Posted February 27, 2013 George, I've never taken PAR readings on the T. squamosa. I did build the LED strips for that tank and adding up the PAR for each LED an estimated PAR is between 80 and 100. (Attached is the PAR table I used for estimating it.)
