Green water

[Le_Jars]

I have a friend whose pool has turned a lovely shade of dark green. In order to sort it out, what sort of questions should I ask them (ie is it a salt water pool or what sort of filtration does it use etc?)

Thanks in advance

It is just algae in the water.

Add a good amount of chlorochoc to the skimmers and pump non-stop for days, cleaning the filter as you go.

Sweep or 'vacuum' the bottom to get the gunk in suspension and through the skimmers and into the filter.

Then get the pool ready for winter, and quick !
