I am hoping someone can shed some advice on a problem I am having with algae starting to show in small corners of my pool
I am in Australia so in the middle of our summer. Over the last week or two, my SWC vinyl lined pool has started getting green algae (I think it is algae) in the corners and also around some fittings such as the plastic outlets on the pool wall. I can disperse it by brushing but a few days later it's there again.
I have had my water tested, chlorine levels are if anything high, Free and total chlorine are up around 7 ppm
Stabiliser level is good, alkalinity is good, salt level is good, ph was slightly high at around 7.5 but otherwise all other readings are within the expected ranges.
The water itself looks perfectly clear, but this algae starting has me worried, last year around the same time I had an algae outbreak of sorts, when the pool walls had visible algae on them. I brushed it off and shocked the pool and all went back to normal, but as chlorine levels are already high I am at a loss as to why I have algae growth again.
Appreciate any ideas or feedback.
