I haven't seen that media before. I like the idea that it is back washable Vs the cartridge filters I am currently using.

The cartridge filtration I am using is cleanable but that involves removing the cartridge and rinsing the debris off of it. In the event of an algae bloom I find I can kill the algae in the pool but the algae trapped in the pleats still is green and is alive despite being deprived of light. I do use a bucket with a
chlorine and water mixture to kill it but the higher levels of chlorine required attacks the end caps.

If I wait till the cottonwoods bloom before I open the pool I have a much better but shorter season.

I look forward to other responses as I am thinking about switching to sand.
