Contemplating a switch to T5's

[Myka]

What type of clam? You may have troubles keeping a Crocea or Maxima in a tank with Zoas and Acans since the latter two are relatively low light corals (or they will bleach out), and Crocea and Maxima are both high light clams. Although a Crocea would be a good choice for your tank since it stays smaller. Both Squamosa and Derasa would be good choices for a 4-bulb T5 fixture, but they both get big. Zoas and Acans would probably get too much light from a 6-bulb fixture imo. When I had a 2x39w T5 fixture on my standard 33g tank my Acans and Blastos wanted to be near the sand, but of course the 39w bulbs are significantly stronger than 24w.

Not allways, My Crocea was doing great in my 45g tank with 4 Tek Light. Little more mantle extension now under the MH, but no change in the brillant colors.

Thanks! I think I am going to go with a 4x24w Powermodule. Now I just gotta see who has stock!

Any bulb recommendations? I want a nice crisp blue with good growth

If you like the blue look try using (2) AquaScience 22000K, and (2) KZ Fiji Purple. Or to be even bluer replace one of the FPs with a UVL Super Actinic. Or for a little less blue try replacing one of the FPs with a KZ Coral Light. That will make the colors pop, and have good PAR.

I second the AS22000 and Fiji Purp. But, took me a while to get used to the Fiji.

From what I've read, the Aquascience 22K have about as good PAR rating (for growth) as you can get from a blue bulb. That's why I've got three
