Good morning, I picked up a Sta-Rite system3 S7m120 filter and pump motor for almost free. It was one heck of a stinky ride in my car. The filters were both covered in green algae. I soaked them in a trash can of 1 pt muratic acid to 20 parts water for a couple of hours. I then sprayed them off.
Here is a picture. Are the filters still good? they both have dangling retaining straps that go around the circumference of filter. They were like this before the soaking.
