Dusty Bottom/Cloudy Water Issues

[MattTexas]

I was out of town last night, but I had my teenager add enough chlorine to keep it superchlorinated until I get back. I'll run the test again tomorrow.

As to the pressure rising - the answer is "not really." For whatever reason, this tank has never showed increases in pressure over time when I use the filter. I flush lots and lots of brown and (occasionally) green gunk out of it when I do backwash, but the pressure never seems to rise. I've had two gagues on it, and they've both been this way. Not sure why.

Still at it.

I was at 16ppm at dusk last night, and I tested about an hour after sunrise and was at 12ppm.

Will repeat again tonight.

Yes. Since you lost that much chlorine overnight, you are still fighting something. Continue doing this. (Re-read post #6 above.) You also need to be checking your CC reading each morning. And, any morning that you have had too big of an overnight chlorine loss, add enough chlorine that morning to get the level back up to shock.
