Is 250w mh to much for my 29g reef?
 

this is a question that is worrying me, i have a 250 watt mh hqi and im worried it is to much for my 29g tank anyone have ne comments?

I suppose that would depend on how tall the tank is. My first guess is that you will be fine. You can always hang the light higher or lower above the tank.

well the tank is 19" tall and the light is about 5.5" above the tank what you think?

I have a 250 watt MH over my 28g tank that is 12" high, the light sits about 5" above. Works well for me.

sounds good, what you think about flow. i have 2 koralia 3s and a 2 and also it is sumpless think i should drill it and go through that or what you think?

I would only be worried about heat. Watch your thermometer carefully, and be sure it's accurate as well!

For flow...what kind of corals are you planning? That Prism protein skimmer isn't particularly effective. If you're planning a full blown reef you may want to replace that with a more effective brand.

yah dude i was wondering the same thing, it is a piece of ****...

I have had a 150 watt MH 3in above the waterline (behind tempered glass). Never used a heater in the tank(78 F)

over what size tank and how long do you run your light for a day?

Sorry....34g 8hrs/day
