fishmanmike01 Posted February 24, 2009 Share Posted February 24, 2009 I am in the process of building two propagation/grow out tanks. Each will be 3/8" cast acrylic measuring 24''x24''..One tank will be lit by 6-24'' T-5's and the other by 1 250 watt metal halide. The question i have to pose is what height do you think would be best for each application? As of now the acrylic is cut for 12'' but this looks awfull tall to me.

CA2OR Posted February 24, 2009 Share Posted February 24, 2009 I normally see frag tanks between 12 and 18 inches. Hope that helps. Quote Link to comment Share on other sites More sharing options...
Mr S Posted February 24, 2009 Share Posted February 24, 2009 8" adjust light if a problem Quote Link to comment Share on other sites More sharing options...
spectra Posted February 24, 2009 Share Posted February 24, 2009 12 is a good number. If you go 8 you are looking at only about 6 to 7 inchs of water in there (thinking this is rimless) It may look funny but 12 is a good number. Also remember with 12 inchs of tank and only 10 to 11 of water that 250 is going to heat the water real quick. Quote Link to comment Share on other sites More sharing options...
R-3 Posted February 24, 2009 Share Posted February 24, 2009 12" is perfect. Thats what I would do Quote Link to comment Share on other sites More sharing options...
Michael7979 Posted February 24, 2009 Share Posted February 24, 2009 Don't forget to subtract or add for your frag tray as this will put the corals closer to the light and surface of the water. If you do a sand bottom then no need for that. But 12-16 should be good. Quote Link to comment Share on other sites More sharing options...
