Re: Low pH Why?
Sorry, I missed the original on this. Amquell lowers pH. As Roger says
here, test. Test after using the Amquell to see what it will do in YOUR
water, as well as in the usual circumstances. The ph will of course be
more stable if the water has some hardness.
The driftwood may be in part at fault, too. However, I have natrualy
soft water with driftwood in the tank and I'll be gaffeled if the pH
(and the KH and GH} aren't RISING. Gotta be the "sand." ALso, the decay
of organic matter will lower the pH. I swear that too much bio colony
will, too, but I have never been able to convince anyone of that.

It sounds like probably your water has very low buffering capacity. You
should get a test kit to measure the buffer capacity (aka KH, carbonate
hardness, alkalinity) in your tank and in the tap water. ...
In all likelihood the driftwood is the problem, but with a reasonable
buffer capacity in your water it shouldn't be so. If it turns out that
your buffer capacity is low, then you will need to add something to
Whatever you do, don't do anything without testing first!
