Cartridge filter better than DE? What are the advantages.... and disadvantages (if any)?The filter is over 20 years old.
Probably time to consider replacing it with a new 520 sqft cartridge filter.
Brush the pool at least once a week to see if the clouding will stop.
What are the current chemistry readings including the temperature and the CSI?
Not really better. About the same.Cartridge filter better than DE?
Cartridge avoids the DE.What are the advantages.... and disadvantages (if any)?
Sand is easiest.Is maintenance easy (I'm only really familiar with sand filters.)
I would vacuum it up.When brushing I am pushing the sediment toward the main drain, correct?
Probably.Would it be just as effective to run the automatic cleaner for several days in a row to get most of that sediment out?
As long as it is not too much it should not clog.If that is diatomaceous earth settling at the bottom of the pool, is there any concern about "gumming up" the cleaner?
Any reason not to switch to a sand filter?Sand is easiest.
If you are going to continue to use tabs, then the sand filter might be a better choice because you lose a lot of water when you backwash which will help control DMH.Any reason not to switch to a sand filter?
That's ridiculous.submitted a proposal to "breakdown and inspect the filter" last year.
If it is DE, it should not be a health issue.Don't think I ever got an answer to the question if this could be a healthy/safety issue for anyone using the pool. Any thoughts on that?
Not defending the pool company, but it's my understanding that anything outside of routine maintenance or any repair over $250 requires HOA approval. I believe that's why they submitted a "proposal". Haven't seen the proposal yet, so hard to say. They may, indeed, be incompetent.... or just gouging the HOA.That's ridiculous.
The filter should be taken apart, cleaned and inspected regularly.
The maintenance people are simply incompetent.
Looks like stabilizer is only “added at time of filling”?This says that they clean the filter at the end of the year.
When did they notice that the DE was coming back?
The chemicals seem excessive.
250 lb of trichlor for 50,000 gallons is 3 ppm per day for 180 days, which is 333 ppm CYA.
So, why are they selling more CYA?
And then you have 50 lb, of granular chlorine and 100 lb of shock.

No.Anyway...... does their quote seem reasonable?
They set the price at $110.00 for the work, which was supposed to already be done.I noticed also (as pointed out by JamesW) that the regular maintenance contract calls for cleaning filters at $110 each.
