Phosphate testing

[PoolDoc]

Right now, I'm working on the theory that you don't need PO4 removers, unless you need them, and that there are 2 groups that may need them:

1. Those with pools prone to recurrent mustard algae, and

2. Those taking long or repeated vacations, and who lack anyone to check on their pool every few days.

It's interesting how this thread has morphed from testing for phosphates to testing the whole need to do so in the first place. I guess the answer (for me anyway) is it doesn't seem likely the effort is worth it. I'll just keep my FC at the upper end of the best guess chart, raise the CYA to about 60 and see how it goes.

It has been worth the effort to discuss the idea here. Thanks for all the expert info.

Happy 4th all

That's a good plan. I find the persistent algae point is inside my wedding cake stairs. Water circulation is almost non-existent there and it's impossible to get inside it to brush--but you can see inside.

Thanks! You, too!

Regarding the question of whether phosphate level control is "worth it", if
(a) you don't have problems with persistent algae in spite of good chlorine levels, and
(b) you aren't having difficulties keeping your pool clear and clean during vacation or other absences,
then you probably don't have a reason to fool with it.
