So back to the coraline lol if it doesn't use up much dkh then why am I dosing over 100mls a day in a zoanthid only sysyem system ? I use h2ocean salt and do on average 25% water changes and that salt has a high dkh in bucket of around 10. No sand no rock no hard corals just egg crate and tons of zoanthids ....and coraline of course
I have to dose to keep coraline alive or my alk drops fast , it's sad but it's fact.
Even if I scrape and make the tanks new which I just did it doesn't stop it for long coraline for me grows fast in weeks I have a tank covered again but if I stop the dosing then my alk and cal levels won't stay up
