Yes, CH now fine. I think what happened: the clarifier made the calcium bind together and formed the sludge that fell on the bottom - which I was able to remove - and what remained was caught in the filter. I refilled the separate spa end with the well water, but this time with a calcium filter...

Got the lab analysis: the sludge was indeed calcium. Today's water sparkles - HC is now 375.

OK - brushed surfaces, vac'ed, shocked, treated according to P/S. Water now sparkling clear! pH 7.4 FC 220 CC -0- TA 125 CH 450 CYA 45 Wonder if there's a way to reduce hardness - perhaps someone knows of a filter? I could pump from the pool throughout the filter and back to the pool? I dropped...

Thanks, bdavis - 1st of all, I misstated water volume: it's 2900 gal (still small). My filter is a fibrous cylinder - enclosed in a canister next to the heater. Tests: pH 7.4 CH 450 TA 300 CYA - not present (black dot stays clear!) FC - can't measure, just added liquid chlorine an hour before...

OK - no replies yet, but here's more info. As the sludge I'm able to vacuum from the floor is so strange, I thought a picture might help to see if anyone can recognize it. The white mounds are the dried, chalky mass - the darker section on the right leading to the bubbles at the edge of the...

I have a very small pool - as it's the "pool" side of a "Dual Temperature Swim/Spa" - a 8' by 18' foot oval with a wall that separates the "hot tub" end from the larger "Swim" end (about 8'x12' with jets that provide current to swim against - think "Endless Pool"). Let's just think about the...
