I was impressed that from very low No3 bounced to 50 , but in my case could be different things not just the switching to aquaforest as some snails dying, or overfeeding...

I have the same issue although I am not dosing AF. I was using FAuna MArin bacto balls along with brightwells bio bricks. water changes have done nothing, so I think I will remove the bacto balls and try carbon dosing using bio fuel or something along with a no3 brick.

surprisingly my corals look fine, but my rocks do not
