Is that gunk algae?

[Chirple]

We recently replaced the heater on our 22,000 gal pool. When they removed some piping, it appeared to have some green slime that looked like algae. I did not see it, the spouse did. Didn't keep a pipe, so I can't comment.

The pool water is well balanced and we deal with an occasional algae bloom over the years. Can algae build up in the water pipes? If so, how do you test for it? How do you treat it?

Welcome to TFP!

Without the pipe, we can only guess what it was. You shouldn't have to deal with an "occasional algae bloom." A cornerstone of TFP is self-testing using an accurate and reliable test kit Test Kits Compared. With an accurate test kit, you can detect chemistry-related issues and ensure enough free chlorine is present to prevent algae blooms. Take a look at the link below to learn more:
