Thanks again for the advice.

Upon your recommendation and further research on this forum, I have decided to lower my TA to around 80. I already have it down to 120.

I did the DE test on the filter and could not see any shoot back through the returns. Pump pressure went up a little over a pound ad has went up three more pounds in the last 36 hours so it may be starting to catch some of the particles.

Water seems to be clearing. Last night the particles didn't seem as bad in front of the light.

I still believe that I have some sand filter issues though. There is a small amount of the fine sand collecting on the step that has not been there before. I can tell a difference between that sand and the sand from the concrete which also collects there.

I will update the results again after these changes.

I have the CYA but am going to wait until I am through lowering TA.

I am also putting priority on tracking SWCG to determine right runtime/percentage.

PS--Source water TA high as well
FC--2.5
CC .5
pH--7.2
TA--160
Ch--150
