Actually quite similar readings on both , but I'll recheck. It's a 73 acre body of water and the pumps have just been installed to cool the water temperature, decrease supersaturation and bringing stability to the water. Incidentally it has alot of ammonia. So technically we r pumping in ammonia with the result that there is a plankton bloom, as we had fertilized it recently too.
It is v strange to have 6ft of water supersaturated.

ANY REMEDIES WHICH COME TO MIND ?
