Hey.
due to chlorine consumption I assumed I had algae (hard to tell as I have a black-bottomed spa).
it's an 1100 gallon spa with vanishing edge and overflow basin (300 gallon).
current measurements are
CYA 40
shock FC 16
Combined 1.0
All other levels are balanced
I'm losing 9 FC overnight even though the water is sparkling clear. I've been slamming since last sunday (5 days) Any thoughts on what's going on?
thanks
