OK, first testing I have done in weeks - many weeks. AMI (Alk Monitoring Invention) keeps me on track with Alk and my pH/ORP/Salinity are all in Apex so I haven't really been following anything else - tank has been looking good - growth has slowed a bit though. Looks like my nutrients are rising so I need to check my RODI and also I really needed to thin out the macro. That done, I think they will start to come down again.
