In a couple threads I have seen people mention that eradication of black algae can be helped by rubbing it with chlorinator or skimmer chlorine tablets.
My black algae is under about 8 feet of water...
what's the best way to do this?
I was thinking I could come up with a way to attach a tablet to the end of the pole for my brush.., but I thought that probably someone has already figured out the best solution.
How are most people doing this?
