Getting serious about water testing finally

[Watermom]

I think Watermom is on her 7 or 8th season with hers

I'm actually on my 12th season with my same sand. I did top off my sand filter this year, but that is the first time I have done so since I bought this filter 12 seasons ago.

Yes, I've heard sand lasts a long time. Just wondering (before I take off my valve!) how do I top it off? Is there something like a fill line I bring it up to? I've also been reading the threads about adding a little DE, and that seems like a great idea as well.

K2006 is finally on a UPS truck heading my way.

Your manual should tell you how high to fill it.

Just make sure that after you fill it with new sand, you start the pump back up with the filter handle in "backwash" mode, let it backwash for a minute or two, then turn pump off, turn to rinse, let it rinse for a minute or so, THEN back to filter. If you don't, then all the dust from the sand will blow back into your pool, and create another week's worth of work to clean up--been there, done that!!
