No takers on this one? One of the reasons for my problem after doing some more research is that I have a lot of cement and block that is unerwater (~60 yards plus the block)that is leaching lime into the pond. I wonder how long it would take to stabilize on its own? I have continous river water going in so that must help, however there is no outflow, just keeping up with evaporation. Here is chart that I found that deals with pools. So if I have a 1 acre pond that averages 5 feet deep and an acre foot of water is 312500 gallons ... 5*312,500 = 1,562,500 gallons in the pond /50,000 = 31.25 * 1.25 = 39 gallons of Muriatic Acid to get me to the 7.6 range. Granted I dont need to go that far down the chart but it is interesting...
Chart No. 2 - Lowering pH with Muriatic Acid
(If pH is over 7.6, add this amount of acid, then retest)
GALLONS IN POOL
pH 1,000 5,000 10,000 15,000 20,000 25,000 50,000
7.6-7.8 1 1/4 oz. 6 oz. 12 oz. 18 oz. 24 oz. 1 qt. 2 qts.
7.8-8.0 1 1/2 oz. 8 oz. 16 oz. 24 oz. 1 qt. 1 1/4 qts. 2 1/2 qts.
8.0-8.4 2 1/2 oz. 12 oz. 24 oz. 1 1/4 qts. 1 1/2 qts. 2 qts. 1 gal.
