When my tank was well lighted and well injected with co2 (DIY), I found this dark-green hairy algae grew flourishingly on my bogwood. Some on the gravels (i used river gravel-manually scoop and cleaned) Few grew on the edge of leaves, rocks and even the powerhead. What I did was to manually remove them. But, they sticks damn hard
. If they were on the leaves, those leaves have to go. They rip the leaves together.
Nowadays, when i stopped injecting the co2, they stop growing, or grow very less. I'm happy for that but sad for my plants.
Any idea (or over-the-counter remedy) to prevent them grow when i boost up my tank back like before?
