Maybe quitting Zeovit

[albert_dao]

Zeovit isn't a bandaid to smother out other problems. Any probiotic methodology will have strict guidelines that need to be monitored and adhered to.

From the sounds of it, your reactor isn't breaking in properly and you're still stuck in Phase 1.

Drew, try this:

Reduce the flow rate to 50 gph or so. Cut the use of any animo acids and/or auxillary supplements (iodine, iron, etc), stick to the basic four. From those, and as mentioned above, I'd do the following:

ZeoBak and Zeofood 2-3 drops daily for the first week after your exchange, switch to twice a week thereinafter. Make sure you're dosing near the feed pump of the reactor and only when it's on.

Zeofood should be added at .25 mL twice daily, again, near the pump and while it's on.

Since this is within your first rock exchange, hang on. Sometimes, establishing the zeolith filter is a PITA, but once you hit phase 2/3, it's smooth sailing.
