Do you ever think of stopping vinegar dosing?
Thanks Mike.
I never considered it because without vinegar I could not keep NO3 below 10, but something changed. Perhaps it's feeding more pellets and less flake, or perhaps it's the matrix I added months ago finally kicking in. I'd rather not use it so I guess I'll see what happens as I lower the vinegar dose.
