This isn't for my planted tank but was wondering if anyone can figure this out...

My African N. multi tank has a KH of 9 and a pH of 7.86.

My tap water has a KH of 13 and I do a 25% waterchange once a week.

I'm curious as to what is lowering my KH? (I also have a coral sand substrate which makes the whole thing even more puzzling!) I do have a couple of Vals and Crypt plants in there and I know that Vals can suck up some carbonate from the water... but this much and this quickly? There's only like 3 or 4 smallish Vals in there.

The reason this is coming up now is that I will be away for a month so no water changes for four weeks. Will the KH keep going down while I'm away? :shock:
