Hey guys, I just recently got a Philips 9W 6500k LED. Specs: 6500k 9W 800 lumens 53.5cm (21") I currently have a 24" 18w T8 6500k with around 1,300 lumens. Do you guys think switching to the 9w LED would be better for a low tech tank? With my current light, I'm getting some slight brown algae on my glass which my otos and MTS aren't able to make a dent to it, and some green algae on my lava rocks, not sure what kind though.. One of them has (I think) cladophora. I currently have: 1 clump of HC - might change/add hairgrass. 1 stunted sword (amazon?) but it seems like it is recovering now 7 stems of anacharis clumped together, currently growing new stems some java moss and duckweed currently covering less than 5% of the water surface. I might add some more plants like java fern and stuff, but I need to get things straight with my light first.
