No ladders or items in the pool, I've been scrubbing sides and bottom of the pool a lot.
Don’t forget to brush/vacuum every day & test fc & replenish slam level as often as possible just not more than once an hour.
Backwash (sand/de) or clean(cartridge) when pressure rises 25% over clean pressure. You never said what type of filter u have & it’s not listed in your signature.
Also be sure to remove & scrub places that algae loves to hide like ladders/steps, weir doors etc.
I have a sandfilter.
