I woke this AM and walked out to the pool. WOW. The DE had really helped. Water was glass all the way to the bottom.
However, i realized that the jets were just bubbling a tiny bit and little water was coming out. I went out to the pump
and pressure was up near 28psi, condensation in the pressure gauge (it rained last night), and the pump was not pumping
much. I have had a small intermittent pressure leak at my filter that occassionaly will allow some air/water out the backwash
port if the valve mechanism does not seal well. I think the added pressure causes the leak to come back and get slightly worse.
I think I need to replace a seal in the filter. I decided to backwash the DE out, and the pump went back to the old pressure.
Probably some of the better clarity in the pool was due to jets not moving the water, but I still think the DE made
a noticable difference. As for backwashing, I had a pretty bad pool starting the season, so I was backwashing every
day for a about a week. Then I went to every few days. Now I am at about 2-3weeks
Additionally, one of my 3 jets seems to have a decent amount of air (bubbles/fizz) in the water stream, even when my pump is holding at 19psi.
Hunting this down is on my to-do list.
All in all I am happy with the DE experiment but I need to hunt down some leaks before I do again.
