Hi all:
I am a pool newbie. Moved into a house over the winter and ignored the pool .. Now I am starting it back up. The pool was green.
Pool is in ground, large and with a DE filter.
Heres what I did:
1. Brough the TA and PH to range
2. Then I shocked the pool with calcium hypo shock. Once i got some clarity I was planning to use the methods listed on this forum.
The filter pressured doubled up and the outflow reduced dramatically within 30 mins. So I backwashed and tried again, even without adding any DE, the same situation repeated.
So then i decided to open up my DE filter (Pentair) and clean out the Grids. Removed them, washed them all out and started the filter again. Pressure was low and good.
Added DE powder. Within 30 minutes same issue repeated itself. I have done this multiple times over multiple days and seem to be stuck.
I have noticed that backwashing does not seem to help, if i open up the filter, and spray wash the grids, I can get 30 mins to a hour of run time before the pressure doubles and flow slows down to a trickle.
Questions:
1. Is this expected behavior and I should repeat until the pool is clear?
2. Or is this unexpected and there are other things i should be looking into?
I found some other threads that seemed similar but there did not seem to be resolutions to those issues. Backwashing is called for twice or thrice a day. My frequency seems to be very high.
I wanted to basiclally get told : Stay the course, this is the way or told that I am doing /or my system is doing something wrong.
