I have a 56g Column 30"L x 18"W x 24" D that I had been running 2x65w CF until I had a ballast go out. I ran 65w for about 8.5 hrs and the other for 4 hrs midday. Im going to switch to T5HO rather than fix my CF. My question is can I get by with 4x24w T5? I know my wpg wont be the same, but the T5 are more efficient. I have Micro Swords, Java Ferns, Giant Hairgrass, an Undulatus and some Broad Leaf Chains. I was planning on going with a pressurized Co2 system soon. I also use Flourish 2x week. Thanks
