The only survivors in my 29-gallon tank so far are two angels and a very tough pearl gourami. After bi-weekly water changes didn't seem to elevate the fish survival rate in my tank, I started monitoring my water quality. I have discovered our tap water has a pH of 6.2 or slightly less. We have extremely soft water. I have purchased some crushed shells and want to add to the charcoal in my whisper 30 filter bag to raise the pH and hopefully be able to add a few more fish. How much do I add in order to raise the pH safely for my angels? Is this the correct methodology? Should I upgrade my filter?
