For the past week, water has been clear, lose 2 FC consistently per day, no slime on walls, but returning "yellow/brown/green dirt-like" spots on bottom of pool...they brush away easily, but come back, usually around the same spots, so I brought my FC up to shock level...this morning, I read here that if it is mustard algae, the shock level should be considerably higher (29 ppm for 50 CYA), so I just added more bleach.....now, I may just be overreacting to the algae thing (can anyone see my battle scars), but I figure better safe than sorry, since we're done swimming for the season...
but my question is, if it were algae, would it have grown substantially in a week's time, since I did not have it up to shock level? It really hasn't affected my water, or grown to cover even 1/4th of my pool floor...it's just that I'd vacuum, and the next day, it would be back...I have considered it possibly to be fine debris, since we've had a lot of wind here the past week....but I'm playing it safe...any tell-tale signs of mustard algae?
thanks :lol:
