I need help to identify a white almost bubble like substance on the bottom of my pool. It seems to gather in the low lying nooks crannys dips. I can touch it and it dissipates instantly. I have an above ground 24ft round chlorine, i use a de filter and when i vacuum the substance up it clogs my filter and i bump it and its ok for a while. Also my chlorine is dissipating at a extremely fast rate. Test result 24 hrs after super shocking with 3lbs of calcium hypochlorite 70% and 15oz of algaecide.
Cyan acid 0 (added 2lbs 48 hrs ago)
Any all help would be greatly appreciated thanks
