My tank has been running for just over 2 months now so it is fully established. However, my alkalinity has been consistently under 7dkh for the whole time. I don’t know what to do as I have tried every single method to try and fix the issue. Tried the baking soda trick, increases salinity, even changes salt brands from aqua forest to Red Sea. I only have a small 5 gallon nano so I’ll only keep softies and zoas, however I’m scared to put any coral in before my alkalinity is right.
