Just trying to find out what level of lighting I have. I was having a problem with blue green algae but have seemed to correct this with many water changes and cleaning the substrate gently. I'm considering led lighting but have not made a decision yet. I may try one on my 29 gallon planted. In addition to maintaining with water changes, I have cut back on feeding, upgraded to an FX5 and have reduced the lighting. I think with my previous filter and power heads I was not getting proper circulation. I'm open to any thoughts or suggestions.
