cowfishlover Posted June 25, 2002 Share Posted June 25, 2002 What power compacts would I want on a 10 gal. reef and on a 20 gal. reef? Link to comment
JIM27 Posted June 25, 2002 Share Posted June 25, 2002 I have 2x36 watt PC's over my 10 gallon(there's a pic of the tank in my sig). Link to comment
SLOreefer Posted June 25, 2002 Share Posted June 25, 2002 2x36 on a 10 and 2x55 or 2x65 on a 20. unless you have the money to get halides for either. Link to comment
cowfishlover Posted June 25, 2002 Author Share Posted June 25, 2002 My LFS guy warned me about the 2X55 for the 20 creating too much heat, light and algea. He recommends 2X36. Link to comment
SLOreefer Posted June 25, 2002 Share Posted June 25, 2002 2x36 isnt enough for alot of corals over a 20. a small cpu fan will fix the heat problem and the algae is not really created by the lighting but the excess nutrients in the water and the spectrum of lighting. having macro algae in the tank can help the algae problem. i guarantee most people will recomend using 2x5 or 2x65 over the 20. many people on the board have this setup. i guess it all ends up depending on what corals you want to keep also. only low light corals will do well on a 20 with 2x36.

leaky Posted June 25, 2002 Share Posted June 25, 2002 I use three 55w pc's on my ten gallon... I have a refugium also which I cool down with a fan so the water goes back to the main tank as the right temp. Link to comment
HuBu Posted June 25, 2002 Share Posted June 25, 2002 2 55W PC on a 20 gal shouldnt be a problem, just get a clip on fan from target to blow out the hot air between the lights and the water. Link to comment
