Reefy Posted March 6, 2003 Share Posted March 6, 2003 Can anyone recommend me live corals I can put in a tank with 2 strips of 8 watt power-glo fluorecent lights? Thanks. Link to comment
Keng Yew, Leong Posted March 7, 2003 Share Posted March 7, 2003 What is the size of your tank? Link to comment
Reefy Posted March 8, 2003 Author Share Posted March 8, 2003 20 gallon high hex. I would have gotten a longer tank but I got it from a friend. Link to comment
Keng Yew, Leong Posted March 8, 2003 Share Posted March 8, 2003 Thats 0.8 watts a gallon.Are you sure your lihting is 8 watts a tube?With that kind of lighting plus a high tank,you cant keep any live corals.Maybe you can try some non photosyntesic(whats da spelling) corals such as sun corals and carnation corals.They need A LOT of feeding.In you tank you will need at least 60 watts of lighting...but the more the better.Try to get yourself a 150 watt metal halide lighting and you will have almost an unlimited choice of corals to keep.Sorry no corals 4 ya....

Lebowski Posted March 12, 2003 Share Posted March 12, 2003 watts per gallon: Hate that rule, it's terrible. AS for keeping corals. Sponges, sun corals, some polyps, and many more can be kept. 60 watts is not necessary in a 20 gallon to keep corals. It just depends on what kind of corals you have. I'd say if you got 40 watts you could keep all the photosynthetic corals+many mushrooms+ some kinds of polyps 60 watts would give you better options, and your corals would definetly like it better if in the right color spectrum (actinincs, 10000k, wahtever) BUT a nice 80 or 100 watt hood would give you plenty of light for all LPS and softies...

sjpresley Posted March 12, 2003 Share Posted March 12, 2003 A 20 gallon high hex is going to be a little deep for 40W to get to the bottom (or anywhere near). Light intensity is deceptive, 2 13W bulbs are not as intense as one 26 W bulb. Fewer larger bulbs with give you more intense (= better) lighting for corals. I am guessing you don't have a lot of space for bulbs, so PC's will be your best, cheap option that will allow you good flexibility for photosynthetic LPS and softies. Link to comment
