devil Posted September 17, 2002 Share Posted September 17, 2002 after finnaly understanding that tempw doesnwt have affects on corals (few tests of different corals for bleaching-I was one of the people who tested the corals) i noticed that the only group that wasn"t tested was the SPS corals group! the testing tank is a 30 gallon tank (something like 39" long 12 wide and 18" high) 2" sand bed and 14" water column 3 gallon refugium and 32" high DIY skimmer (also about 3 gallon capacity) will 2X120 watt daylight(6500k) screw in pc and 18 watt NO actinic be enough? or shuld Iincrease the amount of light? also wich SPS is the hardiest? and wich will my school of yellow tail damsels like the most?

NanoReefer53 Posted September 17, 2002 Share Posted September 17, 2002 Montipora digitata and cap. are great choices for beginner SPS, very hardy and grow fast. Link to comment
Jefe12234 Posted September 17, 2002 Share Posted September 17, 2002 I've never heard of a 120 watt screw in PC. I'm guessing that 120 watts is the incandescent equivalent, which is completely meaningless. How many watts do the bulbs actually use? That said, I'm guessing your tank does not have enough light. Montipora, Porites, and Pocillopora generally tolerate lower lighting conditions than the Acropora that so many people like, but I think you'll still need more light for most of these corals. -Chris Link to comment
devil Posted September 18, 2002 Author Share Posted September 18, 2002 the actual use of watts is 26W for a bulb but it makes a lot more light than that if needed it will be increased with time to 48Weach the 18W actinic is someting I can not change but I think I will replace the NO with a new one soon montipora end pocilopora you say? Il remember that BTW how many watts per gallon do you consider enough for LPS and how many forSPS??? Link to comment
