Filters are commonly sized by the square footage of surface area. It makes sense: the more square feet of filter media you have, the better the filter performance will be. But it gets tricky when you try to compare the three different types of pool filters to each other.
Within each filter type, there are typically four or five sizes. Of these sizes, the smallest are suitable for above ground pools, the mid-range ones can be used for small pools around 15, gallons, and the big filters work best for pools above 25, gallons. These are usually listed on product information pages, and they show the maximum flow rates for the filters.
This snippet below, from our Hayward Star-Clear filter page, seems to suggest that a 25 sq. Not even close. But never go smaller than a this for an inground pool. I have a rule of thumb for cartridge pool filters: sq. I like to see the sq. These can go an entire season without cleaning in most cases.

Dirt can be pushed through the filter, internals can become crushed or cracked, and high pressure makes for a slow, inefficient and potentially hazardous situation. Another rule of thumb I have for pool filter size is to look at the swimming pool size in gallons.
The formula is Length x Width x Average Depth x 7. For oval pools, change the multiplier from 7. A minimum flow rate of 11 GPM per sq. Flow rates over 25 GPM can lead to channeling. Diatomaceous Earth DE — Max flow rate 2. Proper flow rate and pressure are essential to assure a uniform cake formation on the support grids. Cartridge — Max flow rate 1 GPM per square foot of area, can be sized between 0.
Match your pool size in gallons or less with the filter model number. You can find dozens of swimming pool filters at InTheSwim.

So the sf filter would fit in the C? And not slow the flow of water? My PSI start with a clean filter at 22 just want to keep water moving, does not seem to reach the 32 other side. The SF filters are somewhat larger than the C tank, so some plumbing modification would be likely, but nothing too difficult. And you would probably cut the pressure in half, down to psi, with the filter twice the size.
No, you will replace the C filter, cut it out of the plumbing and install the J-C in place of the C, which you can put in the trash, or sell to someone that wants a used filter.
