It’s brand new filter 4 weeks old. What I’m saying is it take longer to filter our shock or soda ash like 3 fuss compare to de which is 2 hrs it stays cloudy for awhile until it’s filtered you think it’s better to go with D.E. filter if I’m a picky person like that
Yes, a D.E. filter will clear up the water much quicker and clearer then cartridge filters. It will also depend on the current condition of the water and the brand of cartridges used. Some work a bit differently than others.
Hayward DE7220 ProGrid D.E. or c7030
I have 7030 its great but I noticed when I shock or add ash or any treatment it takes forever to clear up and more frequent filter cleaning and we early used the pool at all
We would advise you would need to change the filter elements inside the unit you have.
Will the filter vessel clamp provided for the current DE7220 DE Pro-Grid Filters work on the older DE7220 (S/N 107573) filters. Also has the following number in block near Model Number "330M33". Can Hayward provide legacy T-bolt (5/16" 24 tpi x 5 1/2" long SS material), associated sleeve nut, spring and washers for the older style clamp?
How do I backwash my Hayward Vertical Grid DE filter?
When the filter pressure rises 8-10 PSI over the clean starting pressure, the filter must be backwashed. Turn off the pool pump. Rotate the multiport valve to backwash position or slide the slide valve up. When the pump is turned on, the dirty DE and water will flow out to waste. Once the water runs clear, turn off the pump. With a slide valve, push the handle down and start the pump. Once the pump is primed, add the required DE. If using a multiport valve, rotate the handle to rinse. Turn on the pump and let water flow for 20-30 seconds, cleaning out the plumbing lines. Turn off the pump and rotate the valve back to filter. Turn on the pump and once primed add required DE.
(5 out of 5 stars) DE pool filter par excellence

I recently purchased a Hayward DE-3620 filter as a replacement for a 10-yr old Hayward DE-3600, and was initially most satisfied with the ability to directly install the new unit in place of the old one without having to make any adjustments whatsoever to the interface connections with the existing vari-flow valve and external piping. Upon first use, I found welcome improvements had been made to the ease of operating the air relief valve and to the pressure gage with a simple means for indicating changes in pressure from the initial setting and when filter cleaning is required. Having just encountered a particularly heavy accumulation of oak pollen and blosom debris that indicated a need to manually clean the filter elements (rather than the more usual backwash routine) I was most impressed with Hayward's changes to the design of the clamp ring and the relative ease and speed with which the top shell and the internal filter elements could be removed. I am pleased to see that Hayward has continued to improve their already great DE filter product line.

Pros: Great water clarity
Cons: High rate of media usage
The Hayward DE filter does a great job filtering the pool, the water is crystal clear. My only disappointment with the filter is that it does not have a bump feature like some other DE filters that I have had and seems to go through media quicker than my previous filters. The filter was very easy to install.
