I am a new pool owner with what appears to be reasonably balanced pool water but I still get Algae sticking to the side. When I brush it, it comes off easily and you can see the green/brownish algae swirl in the vortex of the brush. I over added Chlorine when I first got the house and it has been stable for the last month around 7ppm so there hasn't been spikes or dips in the amount of FC.
Before I dump a hundred dollars worth of chemistry to try and get everything under control (Shock, Algaecide, Pho remover etc) I wanted to see if anyone has any opinions. The filters are fiber filters that run at 14psi when clean and get changed when pressure increases to 26-28. It is typically taking about 7 days for the filter pressure to rise and is shorter if I am more diligent about brushing the sides (I do it every couple days).
Thanks for any info or suggestions anyone has.
