Hi everyone im making an acrylic tank that measures 24Lx14Wx12H and its roughly 17 gallons. That tank is ready cause I glued all the parts that are in 1/4 inch thick plus the back that is black. Im thinking in adding a hang on filter because I already have it but what do you think about it? Its suitable for tanks up to 55 I believe. Plus I was wondering about using leds of course but specially the Par 38 bulbs. But I dont know if they really work for any corals. Because i want to use them cause they are not a headache for me to be working on canister and drivers and all that. But how many do you think I should get? Or what do you recommend me to use for my lighting? Any opinions would be greatly appreciated
