Photo test: Harmsco filters are messed up!

Wouldn't worry about it.

If it works for you, it works for you. Doesn't matter that it's generally not a good filter, and doesn't have the capability Sta-Rite claimed . . . since it obviously has the capability to do YOUR pool well!

But, to answer your question, the problem is the design, not Sta-Rite's cartridge construction techniques. An aftermarket filter can't fix the faulty design.

Again, the problem is that the filter was designed in such a way that StaRite could CLAIM much more capacity than the filter actually has, after it's operated for a little while. But, in lightly loaded situations like your pool, it can function just fine.

Why is it i'm the only one that wonders how old they are, and how often they were cleaned? Two of the major reasons why filters wind up looking like that. Along with the over-sized pump scenario too. It's easy to blame the manufacturer, when the owner is watching you take apart the filter and sees this, and asks you "what happened".

Edit: never mind. Didn't see how old this thread was...
