well my tank is heavly planteds ,driftwood, clear water, has shutlz aquatic soil (which i think is lowering my PH) and 2 power filters and co2 from yeast, the water from tap is hard to begin with

my GH is at 11 deg
and PH at 6.6 to 6.8

is there a easy way to lower GH and raise the PH with out really effecting the other paramaters.

If you have access to reverse osmosis water, or distilled water, that is the easiest way to change both of those parameters. But it is generally not recommended, using too much of either in a planted tank reduces the concentrations of other nutrients that the plants need. If you have good lighting and can keep the CO2 system running consistently and have fully planted the tank, the plants will use up some of the GH for you.


Aquascape? I'm a crypt farmer.

It's a fine line between fishing and standing on the shore looking like an idiot.

That IS an aquascape, it's titled "The Vacant Lot".

Are you sure your pH test kit is working? Also what is the kH of the water? Is the water being run though a water softener?

I have never heard of the Shultz product lowering pH. In fact every report is that it can sometimes raise pH.

Yeh something just dont sound right there, normally you have an elevated PH with those numbers.
GH is the hardest one to lower, peat or R/O basically only ways.

I would definately retest to be sure and do both the tap and the tank. Either get another kit or even cheaper bring water samples to your LFS and let them check your numbers against those of your own kit.
