Algae or something else?

[pbitt]

Hi everyone... had a new liner installed this year. I've kept all levels in check all summer, pump is ran daily, i havent been doing anything differently. It's been cooler so we haven't been able to use the pool as much, but I am getting these brownish looking drifts on the bottom for the past 2 weeks or so. I haven't had this problem previously all summer. What do you think it could be?


I can send pictures if someone tells me how. Can't seem to figure it out.

pbitt I am pretty sure people will want to see your chemistry results before they answer. Do you have a kit to take measurements?

The new reply topic screen comes up with a little horizontal menu showing a camera, a grey square with two white mountains and a paper clip. If you click on the camera you should be able to take a picture that transfers directly into your message. If you click the white mountains it should bring you to your photo cache where you can select a photo to include. I am working from a Tapatalk app so that is how it works for me. If you are working on a computer in your browser it may be different but look for these symbols. I will go online to help if you need it! However likely the chemistry results will attract the attention of some of the very knowledgeable people who are administrators for TFP. Good luck with it all!!

Thank you Hidden, I think I got it up above? Are you able to see those pictures?

Looks like algae. I would recommend a SLAM.

Really? Dang. Even though if I swoosh water by it, it disappears? I was just in the water Sunday and I brushed the pool and nothing felt slimy... I know that might not be saying much

 

[JamesW]

Probably a type of mustard algae.

 

[pbitt]

Is there any way to tell for sure? I have a new liner and don't want to SLAM unless I have to

 

[JamesW]

No real definitive way to tell that's practical. Maybe send a sample to a lab somewhere. A SLAM should be safe for any good quality liner.

I'm really sure that it's mustard algae.

You have visible algae, the pool needs to be SLAMmed. The SLAM levels that are recommended will not effect your liner.

It's not disappearing when you brush, it is being broken up and dispersed into the water. Algae cells are microscopic, and once you can see them clumping together you have thousands if not millions of cells. It will only get worse as they reproduce faster than they are killed.

No mercy, SLAM the pool.

 

[pbitt]

Haha thank you everyone. I have started the SLAM process tonight.

Just SLAM that puppy
