Interesting Algae Change
My 120 gal low tech, heavily planted tank is doing very nicely right now. Please see the pictures.
I'm curious to a change in algae behaviour though. Back in November last year, when I was using my well tap water for changes, the rear of my tank had a brown algae cover. In December, I switched to RO water for changes, increased the number of Ottos in the tank from 2 to 12, and reduced the number of times my auto feeder runs from 3 to 2 times a day. Since then, the brown algae has died off, and is replaced with a bright green type! Any idea what's going on? The pH of the water hasn't changed noticeably.
Thanks for any insight.
