Core element 3B - didn't dose for a few weeks :-(

[PaulG]

I just realized that 3A core element had not dosed for three weeks. It seems that there was a problem in the line. Now I have cyano build up on sand :-( also a few snails have died off. What is the best course of action at this point? I have fixed the line problem and made sure that the elements are dosed in balance. Is there anything else that I should do at this point? Thank you advance for your help!

3A is just alk and trace elements, I wouldn’t have thought that that would cause your snails too die .. have you seen a drop in your alk at all .. if your alk swing wasn’t too big you should be ok , what are your current parameters at ?
