Is this metal halide too big for a 40?

[reptileguy112]

I want to put a 250 watt metal halide on my 8 gallon nano....would that kill everything? Also the 250 is on my 40g right now and I would be putting this 400w on it from this link. Is that halide on the link okay for a marine tank? http://sacramento.craigslist.org/for/5064063199.html

I wouldn't put a 250 watt mh on a small tank like that.
Seems like it would be impossible to control the heat, even at 2' off the tank.

Don't think the 400 watt fixture and ballast would work out to well either.

I once had a 250DE on a 29H. All I needed was a clip on fan connected to a temp controller an it held 79 degrees easily. Fan would come on for 30 minutes at a time and the heater would run during the night.

big difference between a 29 gallon tank and a 8 gallon tank

The heat would be next to impossible to handle. Light acclimation a nightmare...
A Simple PAR38 bulb would be more than enough to light up a tank that small.

I traded this guy some xenia and acans for a compact power bulb thing (two 24" daylights and two 24" actinics with a fan). I geuss he wanted to get rid of it or something but it works. Actually too big for my nano so I am propping it up with the skimmer and the old light lol. I will probably eventually hang it.

Omg hang that light. Never rest lights on top.

is has a plastic cover. Is letting it rest going to kill the corals?

Why is letting it rest bad?
