Hello All . . .
UPDATE:
1. We swapped out the two AC units w/ KDF55 (containing copper) for units with nothing but AC. We've been running the system (Water Softener output blended with AC output) long enough to achieve our initial goal of pond GH = 50 (vs. 150 from the tap). No change in pond pH; ammonia and chlorine from system = 0. We flow 20 gph 24/7 which overflows to waste via a standpipe in the sump PLUS we manually replace the water lost from flushing the sump and the two Ultima 6K filters EOD.
2. Clarity Unit still produces foam like a rabid dog, even though ORP remains above 320 and nitrates were about 5 ppm the last time I checked. I'm guessing the softer water Here's a pic of the foam produced over a 24 hour period (FYI: The pile starts on a brick ledge located 17" below the output pipe's bottom edge).
PS: The water looks better than ever.
