    Dryden Activated Filter Media and What Model Filter Is This?

    Summer Shield is not the same as Enhance Summer or ACO. I also don't know what it is made of and I sold large amounts of it while working for an industry distributor.

    Dryden Activated Filter Media and What Model Filter Is This?

    A couple additional points to consider. The size of grade 1 Activate is manufactured under strict tolerances to achieve particle sizes of .4mm to 1.0mm #20 grade silica sand is .45mm to .85mm typically There is negligible risk in Activate passing through the laterals vs. #20 sand and if it does...

Captive marine...

    I encourage anyone interested in the Dryden product to do some research on the reason it was invented. Pools that have chemistry fit for human exposure are never truly bacteria free and sand is an ideal environment for bacterial/biofilm growth. The Dryden product was created to create safer...

    Robots That Handle Newer Main Drains

    I hope I can assist, I'm part of the Maytronics US sales team. I won't be able to be on the site consistently and I may not respond to PM's as quickly as I'd like but I want to make sure the info shared on this site is accurate. The M400 and M500 are built on the same chassis. They both have...
