Whats the most powerful light for a 10 gal

[Mik_101]

I would use a 70w MH or a 150w HQI.

I use a 70w 1400K on my 10g frag tank mostly zoos but there is a few SPS frags in there... I think the 150w might be a little bright for some zoos and palys...

I had a 150 on my 12g and didn't have any trouble with zoas or palys if I was careful in acclimating them. I used a pretty high k / low par bulb though. I looked at a 70w but IMO the bulb selection sucks in comparison.

I agree with you there... the bulb selection sucks for the 70w but i had all the stuff laying around... if i was going to keep sps i would put on a 150 for sure... it was a heat issuse for me the 150 was just to warm even in the cold months (i keep it in a closet) because all my avalible wall space is taken up by my other aquariums and huge TV... I need a bigger place for my tanks

There's nobody stopping you from putting a 1000W MH on top of the 10 gallon, but the law of diminshing returns and heat issues probably dictate that 150W MHs are as much as reasonably possible.

I have an incadescent hood with aluminum refectors and picked up 2 coralife 20 watt mini compact flourecent 50/50 bulbs.

10,000k/Actinic

Looks good and was only about $45 complete

May not be the best but works and provides 4 watts per gallon....

just run a 400W 20k bulb like some of the guys on the nano forums do. You'd evaporate your entire tank each day but think of the SPS you could keep! lol
