Hey guys so my tap water is very high in ph. I am not sure exactly how high, because it goes off the test kit that I have for it. It is dark blue when I test it. Im guessing 8-8.5. So I had a friend tell me to use neutral regulator once a week with my water changes to bring the ph down to 7.0. However I am being told now that I should not do that because the TDS would be more harmful to the cichlids than the high ph would be. I just need some more opinions on what the correct thing to do would be? I unfortunately do not have access to RO/DI water. thanks!
