I have been researching a little more on a new light fixture and the Finnex Ray 2 seems to be the right one. As of right now, I am using a Aquatic Life T5HO on my 40 breeder and it is slowly growing algae. A lot of threads I looked at had the fixture for growing plants but the tank I want the new fixture on will only have rocks and driftwood. I just need more algae to grow for my loaches. Will the Ray 2 grow more ans faster algae compare to my current Aquatic Life? I dose 5ml of NPK twice a week, with at least 10 hours of light, to help but I am barely seeing any algae. Would the Ray 2 be enough or is there another LED fixture I have not looked at? What do you think of how it is made? Does it feel or look "cheaply" made? I am not looking to use over $150 as I still have other equipment to upgrade. I rather just use one fixture on this tank as I do not want it to heat up my "temperate" tank.
