Pool was opened a week ago. Was a blue cloudy mess and I have been slamming since then. Now the water looks perfect, but I've been brushing several times a day and I'm still getting those algae puffs, dead algae along the seams, and even an occasional spot where I can see it.
What is making me wonder about mustard algae is that I read in a different post that it doesn't always cause CC. There's clearly some algae, but why so little CC?
These are my numbers.
pH (before Slamming started) 7.6
CYA 40 (based on addition of 6 lbs over last week. Tested when open and it was definitely < 20. Assumed it was zero as I've lost all my CYA every winter prior.)
Salt 1800, but SWG is off.
Another question: According to pool calculator, the 6 lbs of stabilizer would reduce by pH by 0.7. I obviously can't test it right now with the FC so high, but that would mean it would be around 6.9 right now. Should I add any Soda Ash or deal with that when i'm done slamming?
