My filter is returning air bubbles. I m proceeding by elimination.
I watched videos and they mention to check the AG pool filter pump housing cover O ring.
After removing the cover, The O ring does not budge. I Had someone else look at it and they say the same.
I would destroy it for sure if I try to get it out.
I m also afraid to crack the clear plastic cover if I try.
From what I can see, it looks fine but it is like 4 years old (Filter in garage in the winter).
The funny thing is that everyone is having issues removing the cover but not the O ring, me the opposite

Any ideas?

Thanks

The pool looks clean. The backwash looks clean. The chemicals look reasonably good (See below). Salt is lower than usual but still OK. The filter PSI is just above my upper range. (32psi) I open the filter and the off-white grids have become a beige, darker than I have ever seen in 10 years. It is a consistent beige, not spotty. I clean the filter as per usual and it easily cleans up. The PSI drops to 20 (my lower range), but in 15 minutes, it is 22, and in 2 hours it is at upper range again (30 psi). I open the filter, and it is that same dirty beige again. I can't keep cleaning, so I repeated the clean once per week for four weeks. The problem continues.
FC: 7.5 ppm
CC: 0
pH: 7.7
TA: 80 ppm
CH: 525 ppm
CYA: 51 ppm
Salt: 2726 ppm

What do you think? Do I just keep repeating the cleaning process? Could I have an algae and need to SLAM?

After our first backwash this season, pressure went down, air came out the relief valve, but no water . There was a lot of tree bud things that probably made the backwash necessary, could the value itself be clogged? What can I do? Anything else to look for? Thank you for any help.

I have a neglected pool and welcome your advice (long story). The current status:

• Water is an odd mix of turquoise and brown with obvious green algae and possible black algae.
• I have been adding daily liquid chlorine at SLAM level for two weeks, but between sun, algae, and offscale CYA (<20), FC measures offscale low (<0.5) the next day.
• I have floating Trichlor tablets adding trace levels of FC and CYA, for what it’s worth.
• Ph is offscale high (>8.2, but it was 7.6 when I started the liquid chlorine.)
• There is quite a bit of sediment in the bottom, too fine for the skimming net and there are occasional clumps of something that does not want to give up its water content.
• The pump is dead. I have a new Pentair Intelliflo 3 to replace it with.
• The cartridge filters did not seem very effective at clearing the water before the pump died. (Do they really work?)
• The pool needs resurfacing, but I can’t afford that yet (already replaced roof, HVAC, and plumbing, finally getting to the pool.
• I’d like to convert to a SWG and replace the broken heater for the spa.
• This is Tucson, AZ.

If I keep up with chlorine and brushing while getting the new pump installed, will the cartridge filter be able to clear the water?

Can I install my own pump, or do I need to hire a professional? (I’m handy and an electrical engineer.)

Is there a more effective way to bring up the sediment than scraping it up in the net or agitating it so it goes through the filter (when the filter works again)?

What should be my next steps?

I’d be happy to get to a swimmable pool this summer, and deal with the rest next year.

Does anyone know if there's any good places to order Bestway replacement parts from other than Bestway? I'm looking for some replacement top rails for my Coleman (really Bestway) 18ft round pool but they're out of stock
