There has been a huge outbreak of Mustard Algae in the Northern Rivers this year. I don’t know of many pools that have been spared. Mustard Algae is chlorine resistant and really can’t be prevented. The only way to remove it is to treat it with a copper algaecide and even then, we have found only Lo-Chlor Tropical Algaecide and Purex Tropical Algaecide are the only ones that work.
It presents in the pool as a light green tinge and/or a yellowish/brown dust on the pool floor/walls. If you touch the dust, it will plume back into the water and turn the water cloudy.
A few points of note.
