Carl I added some pics from at night with the pool light on.

I take the cart out when I add DE. Dont want to clogg that its a new cart.

I have been trying to keep the chlorine at 13 I thought from the best guess chart.

What I mean with the chlorine holding is I shock to say 13-15. Then the next morning the dpd test is blood red. I know its still high. I dilute the test 1/3 pool to 2/3 water. (RO water. Im on a well) Its still at least as high as it was the night before, but I cant test CC until it comes down to under 5 ppm. Today it was a cc 1

I have a taylor deluxe dpd kit from leslies. I have a oto just for having it.

The pool is blue but cloudy.

I though the carts filter to 10 micron and the sand 30 micron?

The problem is the cart is rated for 80 gpm. My pump is two speed 1 hp. The sand is a hayward 166t and rated for 25 gpm. I put it after the cart to reduce the flow.

Ugggggggghhhhhhhh!!!!!!!!!
