20G Reef Build

I notice that metal halide light would emit A LOT of heat. I might just use my brothers 400w one till i buy another light. What i might do is see how heat the light emits and how hot it makes the water and if it heats it to an appropriate heat i will use the heater at night and the light during the day. Would that work?

400w is definitly overkill, you would just be able to keep the most light demanding corals in the upper portion of the tank and try to shade others down lower. 400w halide will definitly throw off alot more heat than a 250w, but your definitly going to need a heater either way, to help keep your temp consistant.
a 150w or 250w halide will be more than enough light for a 20g.

As for your livestock and equipment list, i don't see any problems (just might be a little heavily stocked, so get a good skimmer) And make sure you pickup some good test kits (calcium, alk, nitrate, pH, etc.)

Lol i was waiting for you to reply. I was wondering, is there anything wrong with the kind of filter and skimmer i chose or are they poor quality?
