The sock is now empty (total of 4lbs), my pH is up to 7.6 and I'm maintaining my CC to 10 with bleach. I've noticed very small translucent / white flakes on top of the water (not alot, but a very light layer on top of the water). Almost like soap flakes (or snow flakes). When I touch one it just seems to dissolve when rubbed between my fingers. Is this a result of the CYA being presented to the water? (or maybe my sock dissolving?) lol. thanks
