Swimming Pool Red Algae Problem

My pool water is clear, but I found red algae on ladder steps and 5-6 blotches on deep end floor. Shoud I raise ppm 10X ?


I would appreciate any input.

Thanks




Thank you for your question

If you have a red algae problem the best way to handle it is to raise your chlorine level up to 10Xs the normal level. This link will give you the best way to handle it:

This chlorine page has a chart for super-chlorination:

Swimming Pool Chlorine

Remember to keep your chlorine level between 1.5ppm - 3.5ppm and check the cyanuric acid level. It should be between 20ppm - 40ppm.

Get a Taylor Reagent FAS-DPD K-2006 pool water test kit. It takes a little getting used to but it's the most accurate kit.

How Do I Get Red Algae Off A Swimming Pool Solar Cover?

by Doris
(GA)

We were gone for 5 days and left our pool running with the solar cover on. Upon return the pool temp. was 91 and we had developed red or pink algae.

We have worked for 2 weeks getting the algae out of the pool, I have cleaned & bleached the pool floats, brushes and swimsuits. The algae is gone but the air temp remains very hot.

We have not needed the solar blanket and will not for a while. It is rolled up.

How can I clean the solar blanket to avoid reintroducing the red algae in my pool? We do not have a large enough deck to spread it out all at once.

I was wondering if when it does get cooler if it would work to super shock the pool and pull the cover over the pool or would that just cause te red algae to return?

I want to thank you in advance for any suggestions!!

Thanks for your question Doris

In the years I did pools in Arizona I never have had to remove algae from a solar pool cover, but I've talked to a few guys who did.

Red Algae..Swimming Pool Problems..Pool Algae

One of them spread the cover out and sprayed it first with a garden hose to remove any debris and loose algae. He filled a spray bottle with 1/2 water and 1/2 Clorox bleach then sprayed/saturated the entire cover, allowed it sit for about 5 minutes, then rinsed the cover off.

The 2nd guy took a big 75 gallons trash can and filled it with water and 1 cup of granule chlorine. He then rolled up the liner, put it in the can, and waited about 2 - 3 hours. He took the liner out and flipped it over to saturate the other side of the liner. Allowed another 2 - 3 hours, took the liner out, and sprayed it off.

Both the them said this technique worked for them.

Hope this helps and let me know how this turns out for you

Have a great rest of the Summer
