schigara, does the auto fill you described basically work like a toilet float valve? it sounds like a simple set up....and I love simple, lol

nice - - so you said your loseing approx 2 gallons a day ....do you attribute this to the sump and all the movement involved in it? and I'm assumeing you top of with your RO water right? not salt mix.......................duh i guess evaporation is evaporation reguardless of whether its 2 gallons a week or 2 gallons a day right? ----i hate it when i anwer my own questions....lol

yeah i bet 500w of MH would do it too.................beautiful tank man

lol - - -if you want to see sparce, clic on my pic bud..........I would like to add a few corals to my tank but they scare me . . . . . I had a very bad start up with this tank so I'm a little on the skiddish side about spending large money on things yet . . . I have 3 true percula clowns {small ones} and a large anemone hermit crab....got any suggestions for corals??? i don't care for shrooms or leathers - - I have quiet a bit of current as well so they would have to be pretty stout, Snowboss

Zoanthids and Ricordia can be very colorful and Xenia like Pulsing or Silver Elongata and Clove Polyps. These would probably do well and grow ok with your lighting but would do much better with something like a Nova Extreme T5 high output fixture. I got the 24in Nova fixture for my display refugium for $60 locally.

They are all very hardy coral that prefer more nutrient rich water and the Xenia work very well for nutrient absorption. No need to have pristine water or even very stable water parameters for the corals do thrive.
