We have been trying to rid our pool of black algae for almost 3 months and I have hit the wall here.
Part of the problem is that I let our FC level drop down below 20 after being told by several folks on here that it was OK to do so because our overnight FC loss had dropped to zero. Well the algae came roaring back and is now much worse than it was to begin with. Plus my spouse (the only one physically able to brush the pool) is having to work overtime a lot and we are not able to brush the pool more than once a day and occassionally not even that.
I have raised the FC level to 35+ and have nagged/bribed/whatever to get my sweetie to brush the pool every day for more than 3 weeks and it is making no visible difference. I am spending $100+ a month for liquid chlorine. I am having to add 2+ gal of chlorine a day to keep the FC at 35+. We are using a SS brush.
We can't keep this up any longer and I don't want the algae problem to get worse. So what do I do?
If we drain the pool and let it sit dry will that kill the algae? If we drain it can we wash the spots with bleach to kill it?
