I am actually using a 75 watt grow bulb and the cheap clamp on lighting fixture. Probably $10 or so at HD
. It is clamped on the 25 gal
rubbermaid container that has about 15-18 gal
of water that is my fuge. No heat problems what so ever. My sump and fuge are in a room behind the main tank though.
*180 gal Display, 100 gal basement sump, 33 gal refugium, 3x250 MH, 2x160 VHO actinics, zoos, some softies, LPS & lots of acros and other SPS.
*100 gal prop tank plumbed into main system w/ 2x96 PC lights and 1x150 MH,
