I have 3 250 watt metal halide bulbs, 10000k, i believe, that came with the 180 tank. Wondering if these will be usuable for a fw tank setup? Seems to be a problem with heat in the canopy- charring of the wood above the bulbs. Wondering about adding a reflector for these bulbs, what length would be adequate, manufacturer? Also, 4 holes, 4 1/8" in diameter, have been cut in the canopy, 2 holes of which have the screw hole remains of a fan mounting. Any suggestions on a quiet fan in this diameter, and would 4 fans be a better choice, with 2 blowing out, 2 pulling in- if they make such an animal? Thx in advance.
