Anyone else think it's funny that this inground pool that has 20
Jandy valves, a spa, a fancy built-in self cleaning system
and a plumbing system that looks like a kludge is using a
cartridge filter? Man, whoever built this was special....
I would have spend less money on valves and bought a

I saw Oren's response and he is right - this pool is in the Silicon
But I don't understand the difference between WHEN you'd put in a
cartridge versus some other type of filter.
Is the cartridge generally for a smaller pool?
Yes. SPAS and smaller pools. Depends on the
environment too. A small pool with little debris,
low load, etc is best suited. If it gets to be a pain
because you have to clean/replace the filters too
often you could switch to a DE filter. But that would
require having room for it and being able to
plumb it into that mess. It would probably make
sense to consider only if you're going to redo that

they packed it all so tightly as they had plenty of room to spread things
For example, they put all the pipes coming and going in a single line.
I would have staggered these pipes because the way they are, they had to
add elbows all over the place to get around each other.
I was able to eliminate one elbow in my recent repair, but, notice I
still had to add two wasted elbows on the new white PVC pipe which I
wouldn't have had to add if the pipes were simply staggered six inches
coming out of the ground:
A simple double line would have saved a dozen elbows (each of which
Does anyone have pictures of 'their' pool setup by way of comparison?
I ordered the 8-fingered wand but of course it will never arrive in time.
So I spent another hour cleaning the filters with the garden hose,
spreading the pleats one by one by hand. I started counting, but at about
200 or so I lost count and just gave up.
My reasoning was that the algae was gonna start again so I'd better get
the filtration going - so I put both filters back in and started it up.
Of course, there's ANOTHER problem (see separate thread) ... but I do
very much appreciate all the help because you guys, collectively, are
like having a great team of professionals helping all of us!
I'm learning. I'm trying to do it today, but I'm learning.
The pool store suggested a spray called "Filter Blaster" but I can't see
how any spray will get inside the pleats if a high pressure hose won't.
The pool store said that the water doesn't get rid of calcium and oil -
but I don't think calcium and oil are my problem right now (almost nobody
swims in this pool so there's no oil to speak of). Maybe once person
swims for ten minutes a week or so and that's it. The darn thing came
with the house. It's like having a pet you don't want! :)
Anyway ... another pool store said they make a finger spreader - which is
kind of what I think I need.
The theory would be I'd brush the fingers along the folds while spraying
the hose at the same time. I guess...

The filter is a little ragged. It seems to be best to aim at an oblique

I guess I should have explained better. The green stuff comes off rather
easily. It's just that there are something like a thousand (or more)
So the problem appears to be mechanical or solvent.
Mechanical: How to get INSIDE each of a thousand folds!
Solvent: How to dissolve the stuff without having to get inside each of a
That might work. The problem though is that the folds are densely packed
so the problem is spreading the folds, somehow.
I found this based on the advice so far:
Here's a picture of the thing in action:
I think you should be spraying from the inside facing out, not on the
outside facing inward. Also, some detergent mixed in with the water
might loosen things up a little easier. Or, soak it overnight in a
mixture of water, bleach, and detergent and then flush it. Sounds
like it got too bad before you started worrying about it.
Next time, I think what I'll do is use the tri-sodium phosphate (or dish
detergent) and soak the filters while they're still inside the bubble.
That would soak the bottom half.
Then, I think, I can flip them and soak the other half.
Then I can wash them in or out of the bubble.
Lesson learned for next time!
Today I'll be fixing the myriad leaks in the lousy Fafco solar panels!
The larger filter diameter is pretty big.
Let me google for the diameter given the part numbers:
Sta-Rite System 3 Model S8M150,
259 sqft cartridge 25022-0203S
191 sqft cartridge #25021-0202S
Total = 450 sqft email@example.com/sqft = 125 gpm@50psi max.
OK. It looks like it's 18 inches in diameter and 20 inches long:

Large Filter (25022-0203): 259 Sq.Ft , Diameter: 18.25", Length: 20-1/8"
Small Filter (25021-0202S): 259 Sq.Ft , Diameter: 25.5", Length: 12.5"
That's a big bucket! :)
