New here, with a question.
Hello, a few months ago i set up a 20 gal planted tank.I have a t5 light bar with 1-10kk bulb and 1-6.7 kk bulb. Im useing florite as a substrate.PH is about 6.7, 0 ammonia, 0 nitrites. I have a patch of micro sword planted (lilaeopsis maurritius) for about a month now. Problem is that its starting to turn a little yellow. i set up a diy c02 system, in hopes that would correct the problem. It hasnt.I know its hard to say for sure what my problem might be, but im open for any input. Thanks PS , glad to join the community.
