Closing early.

[Marty D]

We are closing pool in early September. I’m having knee replacement. Anything I should do? Add more algae 60 ? It’s going to be green for sure when we open it but have no choice.

That's a shame Marty. This early, the chlorine won't last long. I suppose Poly 60 will be in order, but even that has its limits. Only thing I can think of is what if you did somewhat of a partial close by prepping the lines, pump, and filter, but left the pool uncovered. That way someone might be able to add chlorine for a little while longer? Try to stretch things out until October? Then add some Poly 60 just before covering?

What type of cover do you use? A solid cover, blocking all light, will help reduce the chance of a major algae outbreak.

It’s a mesh cover. I can handle green water. Normally I seen that happen and shocking it will clear it up with a vacuum- dumping the water as you vacuum. It’s that black algae that is hard to get rid off. My question is. Will it turn to black algae? I’m using all 4 qt. Shock it. I’m going to leave the floater in with the submarine- both together can hold 10 -3 inch tabs . Thinking the chlorine will last 3 weeks brings it into October. Im also pulling the filters out when dumping in the algae 60. I feel the filters catch most of the algae 60 and doesn’t go into the pool water. My 2 cents???

I close several pools after labour day weekend, all open to clean water. Make sure you shock the pool a week before closing, let the chlorine levels fall to normal. 1 quart of poly 60 for 15,000 gallons. Then cover.

The key is insuring not a hint of algae is in the water.

How would you qualify "shock the pool"?

Why let chlorine fall to normal?

Why let chlorine fall to normal?

Probably because excessive chlorine levels tend to oxidize the algaecide prematurely.

Raising chlorine to shock levels insures there is nothing nasty lurking. Letting the chlorine drop before adding poly60 insures full strength of it. Cover and that pool will be clear come April.
