250watt se halide on 20g?

[Starry]

no fish are planned at this time, just corals and a few snails. was thinking sps on a egg crate rack. zoas, maybe a colt on the bare bottom under the rack. all rock will be in the sump. if algea gets its foot in i might think of adding a mower blenny.

as long as you can keep it cool it will be a good set up.

250 mh is over kill for a 20gal

i would be looking into a 150 for a 20gal if i were you. your going to have issues with evap and heat and on this note, is a $400 chiller really worth it in your 20gal??

its not overkill I have never had any heat problems what so ever, and don't run a cooler. My light sits 4" above my 20 gallon and my corals are freakin' loving the amonut of light being shed above the tank(19 Watts per Gallon). Plus i've fragged one piece of Xenia and its doubling in size almost every second week , so just keep an eye on your water temperature/evaporation and phosphate levels because with that much light, algea growth is to be known to be a problem(if using normal tap water like i do)

heat shouldnt be an issue as it will be in my basement. i never use tap, at the worst ill go buy it at the u-fill ro place down the street.

you'll be fine then, I'm a lazy/cheap reefer so I use tap water, but have just recently set up a reactor for NP Pellets so tap water can be used
