40G Breeder 150 Watt enough?

[golfschosen1]

I own a 40G breeder setup and am trying to frag small Acros and some LPS too, does anyone know if a 150watt 20,000, is enough light? It seems to be up to this point it is curently sitting in an Aquamedic pendant

Thanks

dimensions?

Id recommend 2 MH (possibly with PC supplement)

Well the 40 breeders are a long flat tank, 3' so I doubt that one MH will sufficiently cover both sides. You could probably get by with one until you fill up a little over half the tank. Then you would have to spring and get another. The 20k is a very blue bulb. I use 10k with VHO actinic supplement but I have heard of several people using 14k and having better luck than with 20k. Just my $.02
