Bring the SG/Salinity up first, this should improve the PH. You'll need to
do it slowly, ie. 1/1000 point per day over a few days. Not sure what the
conventional wisdom dictates regarding the final salinity level in your part
of the world; your LFS should be able to advise on their conditions as a
guideline. My tank stays at about 1.024.

Once the Salinity is good you can focus on a good buffer if needed, I use
Tropic Marin triple buffer which costs about 11 British Pounds or about U$19
at present exch. rates. You'll need a test kit to measure the calcium and
alkalinity/hardness. Again you need to make smallish adjustments here and
adjust one with consideration to the other.

Hope this helps.

So, what are your suggestions for getting the water chemistry right?
Bring the PH up first? How best to do that? Add the aragonite *first*,
as a buffer? There's a kalkwasser generator in the cabinet that's yet to
be brought online...
