I don't want to get the thread off-topic but a properly operating filter of sand, DE or a cartridge will all capture enough of the dirt, etc. to keep a pool absolutely crystal clear.
If a filter is blowing back visible "junk" into the pool, there is something wrong with the filter.
We really ought to start another thread in "pool equipment" if there's more discussion on filters but I wanted to bring up this very common subject.
End of hi-jack
OK, Dave. I started a new thread.
I have come to the conclusion that you are exactly correct. My pool is crystal clear, but I feel that I may have a cracked lateral as once in a while, I get sand/dirt back into the pool.
I do plan to replace the sand and laterals next spring and finish out this year with what I have. It works great for the time being and only does this when I backwash the pool.
Plus I think the sand is starting to deteriate as some sand is blowing back into the pool.
I plan to go to Zeobrite with new laterals next year. Any comment on using Zeobrite? I have heard all kinds of things, but it says it should last 5-8 years easily without having to change anything?
What are your thoughts on that one?
