Overkill Possible?

[qazplm25]

I was just wondering if it is possible to have too much light.
Like if I had a GSP or a low light needing zoo or something and blasted it under 250 watts metal halide in a 10 inch deep tank. Would it just grow REALLY FAST or something else. After acclimating it of course

If a coral comes out of low light into very high light it can do some damage, yes.

Also depends on the par of the bulb.

If you are talking about your 10 gallon, a 250 is crazy imo. So for a 10 gallon, yes way overkill IMO.

Even a 150 may be to much for heat and also overkill.

If you want MH, a 70w MH will probably allow you to keep anything you want in a 10 gallon tank. T5's also another option.

You can have too much light in any tank, IMO.

Too much light depends on what type of corals you're tring to keep and where they come from. GSP and Zoa would be too much light. Watch for temp.

I think a 150-250 on a 10 isnt that bad, but you need to adjust incoming coral in a nearby tank maybe.

Heat is going to be his main problem with a MH on 10 gallons.

As long as you have fans blowing on the bulbs and the surface of the water it is fine, I have seen many nanos with halides.

 

[TomD]

Yes, but there is no need for 250 or 175. You can get the same results with less wattage.

It is not an over kill, it is a kill. A 250w will boil the 6 to 8 gallon of actual volumn of water in the tank.

My 10g has a 150mh and I honestly think it isn't enough, mainly because of the really low par on the bluer bulbs. I wouldn't upgrade due to heat problems, but once I get a larger tank I will have a 250mh.
