Question on new Pentair Clean & Clear RP Filter

[jayjayaz]

Please advise on understanding guidance in manual for new Pentair Clean & Clear RP Filter. It says note; "When the cartridge is element is used on new pools and after cleaning the elements, introduce into the system .5 pounds of diatomaceous earth per over 100 square feet of pool area. Mix it with water and pour it into the skimmer after pump is running to enhance filtration.

My pool isn't new, but the filter and cartridge are, do I add the DE under my circumstances?

Thanks in advance!

That is written pretty strangely.

I think adding DE is optional (although not usually recommended in cartridge filters), just like for use in sand filters. What is weird is the amount added should be a function of the sqft of the filter, not the pool, IMO.

EDIT: I just pulled up the Pentair manual for the C&C RP filter and see no mention of DE in it.

EDIT 2: Found it in the manual. It says add 1/2 pound of DE per 100 sqft of filter area to enhanced filtration.

Sorry, you're correct, I poorly copied the guidance it says:

"When the cartridge element is used on new pools and after cleaning the elements, introduce into the system .5 pounds of diatomaceous earth per over every 100 square feet of filter area. Mix it with water and pour it into the skimmer after pump is running to enhance filtration.

Thank you

I was too slow and didn't see your outstanding edits; so I guess my question is does this guidance apply to my situation and is it recommended?

Thanks!

Is the water not clean enough for you?
Seems pretty optional to me. You can if you want.

BTW, realize we recommend cleaning the filter when the pressure rises 20-25% over your clean pressure (prior to DE), not the 8-10psi the manual mentions.

Thanks for tips; water is clean, just wondering if it's worth the extra trouble

It is definitely optional and not required. Only as an enhancement if you are not happy with how clean your pool is. My opinion it is definitely not worth the trouble to add. Or what it would likely add to the effort required to clean the cartridges and increase to the frequency of cleaning if it clogs up faster.

Technically yes that does apply because your cartridge is new. However, I agree with the others that you are (just slightly) better off in the long run if you don't do it.

I agree with everyone else.

I would like to add though, that how clear your water is depends on your water balance also. Keep your water balanced, and you will be golden, no matter if you add DE or not.
