Hoping to get some advice here. I have a recurring mustard algae issue- I get a bloom 2-3x per year. I follow all the TFP rules religiously, keep my water balanced according to Pool Math every day, brush/vacuum every week, filter every month, etc. I do everything as advised from what I can tell. But sure enough the bloom shows up every 4-6 months. I have read here that I shouldn't be worrying about phosphates but I'm out of things to perfect, so- should I go ahead with a phosphate remover? Phosphates are around 500. Just finishing up a slam (and for the record, I SLAM properly too, brush everything- I promise, it's exhausting!) but my regular numbers are: 8500 gallons, CYA 45, FC 6, PH 7.6, TA 60, CH 380... Cartridge filter, Pebble tech surface, Florida climate... Would love any additional thoughts. TIA!
