What kind of cartridges do you have? Many cheap knock-off carts don't do the job no matter how much they cost. Filbur, Unicel, or OEM are the only ones recommended here: Recommended equipment for new inground pool.

Re: Replacing cartridge with sand
The advantage of sand over cartridge is the ease of cleaning the filter. For a sand filter, you simply turn a handle on the top of the filter a couple of times. The whole process takes about 2 minutes tops. Simple, simple. Personally, I will never have anything but a sand filter.
Re: Replacing cartridge with sand
I was under the impression that cartridge filters smaller particles that sand does not. Am I mistaken?
Cleaning my cartridge probably takes 10 or 15 instead of 2.

I only trust the k-2006 titration is better for me
Re: Replacing cartridge with sand
If you have quality carts that are in good shape and you're still unhappy with water quality you could try using polyquat 60% to see if it helps filter some of the smaller bits.
An oversized sand filter will filter better than a smaller one (as long as it can be backwashed). With sand you can also polish the water with a little DE to catch finer bits than the sand can by itself.
Some parts of California have water use issues. Is water use limited where you live? Sand filters require occasional backwash - dumping water which must be replaced.

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

Re: Replacing cartridge with sand
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.
