lighting help

I have a 46g bow with a big fat center brace so far my thoughts are either a single 400w mh 20,000k with two 36'' super actinic vho's, or two 250w 20000k,s with know actinic,s suggestions please.

if you are just looking for suggestions, I would say 2 250 10k's plus VHO or PC actinics. If you are looking for expert advice, then maybe someone else can help :) I think the 10k's would give you more par and better growth then the 20s

I think the best way to approach this is what do you want to keep in it and what are the dimensions?

[wjhuie]

clams, lots of acro's some ricorida an some zoo's around the bottom

Tank dimensions?

[wjhuie]

36'' long 12'' wide 16'' wide in the center and 20'' depth

keep in mind that i dont have a chiller just 2 4.5'' fans

Depending on your layout you could use one 250w MH with a good reflector. Pick a bulb/ballast combo that has good PAR and leans toward the blue side of the spectrum and you wouldn't need to have actinic supplementation ( don't NEED it anyway.)

In truth you could use a 175 set-up if you picked wisely.

These options would save money and reduce heat concerns.

I just ordered two aro pro series 250w 20'000k xm with the spider light reflectors, and two 4.74'' fans that do 80 cfm each. For right now this will be a sumpless system with a remora pro, to seio super flow 820 and a wisper 30/60. I heat becomes an issue i could install a sump to aid in cooling. any suggestions
