Algae or somethimg

[Doug M]

Getting dead algae (I believe) on the seams of my pool. I vacuum to waste. I have a sand filter. Pool is all clean and clear. After half hour or so the algae or whatever it is comes back. Any answers? Thanks in advance

Please post a full set of pool water chemistry test results from your own test kit.
I suggest you read through Pool Care Basics - Trouble Free Pool and even look at a few of our videos TFP-TV - Trouble Free Pool

Water is all balanced and clear. After I vacuum to waste, about 30 mins after dead algae or fine dirt/dust accumulates on the seams again

Probably the dead algae is suspended in your pool water and sinks slowly and accumulates in the seams. However, that probably also means you have live algae that causes what you are seeing.

A SLAM process is perhaps called for but a complete set of test results is needed to be definitive.......we're kinda' guessing without them.

It also doesn’t accumulate as much or as fast with the pump turned off

Pump on, you get more flow across the seams, depositing more dead algae

So give it a good shock and vacuum and go from there?

Well, no. We use a process called SLAM to get rid of algae permanently. We never "shock" a pool.

Here's more info

SLAM - Shock Level and Maintain

We’ve all had to deal with a green pool. Clear algae from your pool with a SLAM! Read here to use shock level and maintain to clear your pool.
