    EZ Test Pools

    Posted by Marie on Jul 1 2020

    EZ Test Pools stays current on tech, is a vast resource of knowledge, and goes out of their way to ensure customer support/satisfaction. I was receiving misinformation from other pool companies and the manufacture of a product. I became frustrated and Robert did not waiver on his advice or give up on me. As a result, I did not buy a high ticket item other pool companies incorrectly stated were necessary and the manufacture corrected its unethical stance. EZ Test Pool Supplies is a rare bred and has earned my customer loyalty over surfing to save a few bucks.

    For my Oasis Z5

    Posted by Unknown on Mar 15 2017

    I love this filter for my Oasis Z5 and E-Z had it for the best price. This filter clears out a lot of debris (dust, sand, worms, leaves). I rinse it out every time to make sure the dirt does not get caked onto the filters. If you let the dirt remain after a cycle of cleaning and don't get to it the next day or two the filters will stain and may get clogged.
