I have 2.5 w/g t5ho on my 55g and 30g goldfish planted tanks. I have some algae, GSA I think, but it's not an invasion, just on some of my plants and here and there on decorations. Today I started using Excel and I am waiting for my dry ferts from Green Leaf. Right now I use root tabs, flourish, flourish iron, Fleet enema and Epsom. I do 60% wc weekly on both tanks. New to this hobby(since Sept the 1st) and I love it. I vote for reduce lighting period, but as I said I am new to this.
