My 55 gallon tank has been setup for around 6 months now, and I continue to have diatom issues. It is covering my crypt leaves and hornwort the most, as well as alot of my substrate and glass. I remove it manually about every other water change. I have kept up weekly to bi-weekly water changes, depending on how unsightly the diatoms get. It has recently gotten worse after I upgraded my lighting to two 48" t8 tubes.
I am dosing weekly with Flourish comprehensive, and my lights are on 8 hours daily. I would say my tank is moderately planted.
I realize in the grand scheme my tank hasn't been up for that long, but I feel like I should have made some headway with my diatom issues. I figure upgrading my lights has likely caused some more balancing issues that my tank needs to figure out as well. Should I just stay patient, continue to remove manually with water changes, and keep the faith? Any advice?
