Replacing cartridge with sand

[dansdad]

I'm not sure of the water quality Dave but I do have a fresh bottle of 60% polyquat here. I will give it a try. Thanks one Dave to another

Earlier you said that the "pool isn't all that clean" is the reason you are considering filter change. I thought that meant water quality (to me: little tiny stuff in water that makes it look dull). Did you mean something else by clean?
No thanks needed (but appreciated), I like to help.

And, Dave, we appreciate all the help you do give! Thanks!

Right back at you Lisa.

what I meant was sometimes the filters seem like they don't do enough to keep the pool free from debris. The sweep works fine. Thanks, Dave

You could either have inferior brand cartridges, you are not cleaning them correctly, or your cart is too small for your pump.
A properly sized cartridge filter, properly maintained, should perform better than a sand filter but not as well as a DE filter.

Most people here don't like them because they are tricking to clean, but those who figure out how to clean them well, and with little effort, swear by them.

I have decent cartridges but I need to find a better way to clean them. I saw a device where you lay the filter down in a tray and run the spray nozzle over them, plus I may need to get rid of a couple. How long are they supposed to last if cleaned twice a year? Thanks to all Dave
