you guys think this would be good to use over my refugium? im going to have mangroves and chaeto. and from what ive heard you need 40 watt to keep mangroves. click at the bottom on the two light bulbs that you can use. im going to get the two 25 watts so ill have 50 watt, but should i use blue or day light?

this is the only one that would fit my refugium
