IGP, 80 000 liters changed sand this year,
I spent a month and a half with milky white water and my water presure in the pump droped to 12 pbs instead of 20ish ! I spent hundreds of dollars on treatments, had specialist test my water ! ( all was perfect everytime, i.e. PH, TA , FC etc... ) however it remained milky white ! today I for the 4th time was cleaning on drain, cause I used a floculant, after I backwashed and rinsed, out of no where there was a loud noise and the pump basket got all white and looked like it was going to explode ! I put the pool back on rinse for a second time and VOILA ! the pressure whent back to 20psb and everything seems back to normal ! what could that have been please as to not repeat !
thanks

Sounds like it was a pluggage that all of a sudden let go.
Tell us more about your equipment and post a full set of test results.

Does this count as one of the things that can go wrong with using floc?

Just curious.

will let you know asap ! ....

I've been around floc use in industry over the last (too many years to mention) and it does tend to plug up lines under certain circumstances.
