So awhile back I bought a two foot and 4 foot T5HO fixture from hydrofarm and I was growing some plants under there. It worked great, but I have since been bored of it and wanted to use it for something more interesting to me for something like a 75 gallon aquarium and since I dont know where to sell them and probably no reefer will buy them I figure they might work for a 75 gallon tank I have in storage. I realize this brand is not for reefing, but how different can it be. These lights will not be permanent as the tank I am going to set up in the future will be red sea reefer xl. and I hope will be able to grow some hardy soft corals. Also as long as I get the spectral output and and color temperature with enough par I bet I could grow some softies. What are your thoughts. I will provide a link to the brand of t5 HO I bought and the unit I bought. let me know if this will work and if it will I am unsure as what bulbs to replace for a reef t5 HO fixture that will work with the hydrofarm fixture.
