I currently run one 48' 6500k T8 bulb on my 55g that I run 9hrs a day, I have mostly anubias couple amazon swords and floating wisteria and pennywort. Growth is very slow as expected but plants looks nice and green, I fertilize once a week with flourish comp. My question is I also have a double strip fixture and have used in the past and every time I used it BBA became a problem and browning on my floating plants, I ran it for 8hrs a day and increased fertilizer dosage to twice a week. If I do a 4 hour on 2 hour off and 4 hour on lighting period will this possibly stop the algae? I have a community tank with about 30 mostly small fish. Ph is 8.2-8.4, dh is 12 and temperature is 76-77.
