Suddenly over a period of days, my tank started looking bad. Half the zoas wouldn't open, my torch and hammer were much smaller, the green hair algae issue (tank is only 3 months old) was suddenly brown . I tested and tested and tested, Red Sea, Hannah, the LCS with Salifert. Everything seemed usual.
Then I started getting lots of brown buildup on the glass. So, as I'm scrubbing the tank I suddenly notice that nothing is coming out of the main return. This was masked by the fact that I have two return pumps (so the water was turning over a little) and powerheads, so there's lots of surface action even without the main return.
Now, Apex gave me no indication anything was wrong. The lights on the return controller were all normal. Fusion looked perfectly normal, even showing my supposed flow rate. There was no outward appearance of an issue in any way.
But the main pump had not been on for almost four days. Yikes.
So here's the status:
If I set the pump to On in Fusion, it flows at 100% and cannot be adjusted at the controller.
If I set it to Auto, it doesn't flow but appears like it is in Fusion as well as on the controller.
If I reboot the controller and don't connect it to the Apex, it flows and I can adjust it.
So, it works just fine if it's not attached to the Apex. (The secondary COR20 works fine if it is attached to the Apex.)
But as soon as I attach it to the Apex, it stops working. The Fallback status is marked as ON. The unit's IQ-Level internal failsafe settings are Min 5% Max 30%.... they did nothing. I thought that was supposed to kick in if Apex stopped controlling the unit.
The unit's Advanced Configuration in Fusion is nothing more than a single line to turn it off during Feed Mode A.
What the heck is going on? Anyone have an idea? The unit works perfectly fine... unless I plug it into the Apex A3 Pro. All equipment is new.
