Desperate for answers on Mustard Algae

Hi, John,

Sounds like your on the home stretch. Just a reminder....don't give up. Keep that Cl right up there 'til your water looks like you want it to.

I have never been a big proponent of vac to waste. I think a lot of it depends on your filtering capacity. I am lucky to have a huge filter.

If you have gotten this far and you feel like your filter is doing a pretty good job....I'd let it do the work. Of course simply vacuuming in the "filter" position is very helpful.

Good work, John. Keep your Cl up.

John you don't have to vaccum to waste. I suggested it b/c a. the algae clogs the filter much faster and b. Mustard Algae is very resilient and getting out of your pool reduces the risk of reoccurances. You would be suprised how little adding an inch of fresh water affects the pool chemistry(at least in my pool). Since you have been having a problem with the ph bottoming out it may actually help to add fresh water.
Also should have added some more detail regarding vaccuming. By vaccuming I mean to get out the large deposits sitting on the bottom. I would only vaccum long enough to get them out. I would angle my return so that the flow of water would push everything to one side. Don't be afraid to add the poly 60 as it has no negative affect on ph, cl, etc. I have had great success with it the last 2 years.

Good luck and enjoy your vacation, Joe
