    Hello All!

    I'm not sure if anyone has tried this before but I figured I would try asking anyways. Would it beneficial to use my old tank water (the water I remove during water changes) to water my catnip plants. I figure that this water is high in beneficial nitrates for the plant but am unsure if the higher pH (8.2) would harm the plant?

    Catnip needs soil with a pH between 6.1 and 7.8, so you're used fish water is just is little to high in pH. I'm not sure if watering your catnip with the water would be harmful, or not though because of how close the pH level is to what it needs to be.

    My water from the tap is 8.2 and my catnip plants grow great.
