Jeff D,

Your water chemistry looks very similar to mine; hardness and alkalinity almost off the charts. If you truly do need some alum in the future no need to bother with the sod. bicarb as with water chemistry like that it's really hard to drop the Ph.

That "Clearpond" or a similar product called "Phosclear" is severely overpriced btw vs. just plain alum if you find it at the right place. All it is is alum and sodium bicarbinate to cushion a PH drop in low PH and low alkalinity waters.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
