Purple

[Carpool]

This morning, my husband opened our Aquabot Turbo, removed the filter, and noticed a dark purple liquid pooling in the bottom of the unit. It wasn't viscous, and washed away easily. He cleaned everything and put it away.

Our concrete pool tends to run basic, so after checking the pH, he added some muriatic acid. Later, he added some bleach as usual.

Now, the entire pool is a lovely shade of lavender. I've never seen anything like this. I realize that certain metals can color the water, but this seems to be related to the Aquabot issue mentioned above.

Any ideas? The pool was normal this morning, with the very slightest hint of green.

I'm not sure what the purple stuff is, but saying the pool was normal with the slightest hint of green isn't normal.
Can you post up a set of test results ? Is the green a clear green ?

Posting a full set of test results would be a big help and allow us to narrowing down the possible issue.

Also, do you know if there is any copper in the water? High copper and high cyanuric acid can sometimes cause copper cyanurate to precipitate out. Google copper cyanurate to compare pictures to what your stains look like.

Carpool,

Do you have any follow-up on this issue?
