So guys I've been dosing 5ml daily of kalk saturated vinegar for a few of weeks. My refugium is doing great. My chaeto is growing well and I have HA growing in the fuge as well.
However, in my main display I have some cyano and small tumbleweed areas of HA. I've been doing weekly 10% water changes. I run GFO and a small amount (I just removed) of ROX carbon. No detectable NO AND PO per salifert.
Should increase from 5ml? Should I just stay the coarse? Thoughts?
Is the vinegar dosing causing the issue?
