Staggered lighting photo period..

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.

intensity sounds like the issue, if you want to see increased growth go with co2. I can explain further if you like

If everything is growing fine with the single, why do you want to go with the double?

Yeah, I'll just stick with the single. Just seeing the plants growing so slow can become a little frustrating at times when you hear others on this board getting much faster grow. I've never been able to get balance with 2 bulbs, it never worked for me. It was frustrating seeing my pennywort stems melt so much from the acclimating to my light. I had bought like 6 bunches and now I have just a couple stems that didn't completely melt and a lot of little twigs. Seems as if they've finally adjusted as I'm getting growth now and no more melting. I have it floating

Oh, I figure that if they are growing, all is good. CO2 and high light just sounds like more of a hassle and if the balance is off for any reason, things can go south very fast... I would prefer to have some time to think and make small adjustments as needed.

Of course if you had plants that need the high light levels, that's a whole other matter.

I've floated all my pennywort, I prefer it that way now.

When I had my 55 gallon up and running I had it with a dual T8 fixture. The bulbs were just GE natural daylight bulbs 6500k.

I had the best I can remember Pennywort floating along with by Jungle vals on the surface (they just grew that tall and never stopped!). I would tend to get bba on the floating plants from time to time. Through here's the thing *if* I didn't have the floating plants I would get the bba on my rooted plants like crazy so I just it alone on the floaters as they would seem to manage.
