BBB method for 3-4 years
22' AG Intex pool
Cartridge filter (sand setup got taken by a flood, using cartridge setup for opening)
Pool did not get covered over the winter. Work away from home prevented me from doing so.
Located Southern WV
SLAMed for 3 days at FC 15, noticed a bit of change then been slaming at 25-30 FC for mustard algae. Not sure if that's what I have, but water kinda looked like it. Been cleaning the filter and running 24/7. Brushing and dip netting pool too.
FC drops 5ppm overnight.
Not sure what to do now. Try store algaecide? Drain, clean with bleach and refill?
