Another cloudy water thread...can't seem to fix it

Ben, thanks for the info...I started to think that's the way I was needing to go. I'm leaning towards just spending the money to get a two speed motor. What motor and impeller do you recommend?
I jumped the gun on the use of the EcoKlean cellulose based product...How do I check to see if it gummed up my filter?

Open it up and see what it looks like....

What motor and impeller do you recommend?

The safest choice would simply to be to simple replace your existing motor with a new 2 speed of the size, and add a timer.
B977 motor on this page at A1PoolParts. I think they have free shipping on energy efficient motors till June sometime. And, you need the "Go-Kit"

This timer is what you need (or you can use the manual switch):

Intermatic T10604R Pool/Spa Control Center T106M and T104M
Southwire 55189301 3/4-Inch 6-Feet ULTRA Whip-Pre-Assembled with Wires and Connectors
Leviton 1282 15 Amp, 120/277 Volt, Toggle Double Throw @ Amazon

Ben, thanks for the recommendations. After working with my installer I've decided to do the following:
Change out the 1.5 HP motor for a 1 HP 2 speed motor with the proper impeller.
Change out the existing T104 timer control for an Intermatic P1353ME electronic control to handle the on/off as well as the timer duties. It fits in the existing Intermatic enclosure box so that simplifies things a bit.

In the meantime, my water has been getting clearer. I'm keeping the FC >10 as you mentioned. There has been a little bit of settling by leaving the pump off overnight, but not a lot.
I've been adding half a solo cup of DE after backwashing and it settles around 1-2 psi increase after about 20-30 minutes. After just a couple hours it increases to 5psi and it's ready to be backwashed again within approximately 6 hrs when the pressure has increased approximately 10 psi. The DE trick does work, but its' a slow process. I'll get there.

I really appreciate the help on this topic and will keep updating as things continue to clean up. Hopefully things won't get worse. I'll also post back after I get the pump and controller installed.
