never, i repeat, never add chemicals to raise or lower ph, it is dangerous, costs quite a lot, and is even worse than having a bad ph in the first place.
The reason of this is because the chemical only lasts for a very short time. An example is
Current ph 6.5
Wanted ph 7.5
You add ph plus
your ph is now 7.5
Two days later it is back to 6.5
your fish are now dead.
It is a high swing of ph, from 6.5 to 7.5 immediatly, and from 7.5 to 6.5 immediatly, within 48 hours. Fish can adapt to a wide varriety of ph so let them adapt to it.
