Biocube 29 3rd chamber water level changed....

[Difrano]

I have my Biocube running for 2 moths with no issue, I have my water level on the 3rd chamber with the return pump like 1/2 an inch above the max level mark, this to avoid the micro bubbles, i made a new mark at that point, Two weeks ago i added a Hydor ATO and things have been running nice.

 

This morning I wake up and the ATO high level alarm was off, when i looked at the tank the water level was like 1 1/2 inch above the mark, i tough the ATO overdosed overnight, so I checked my salinity and was at 1.025 as always so no problem with ATO, and middle chamber level look like the same as always.

 

I may think that my return pump is not pumping enough due to damage or clogging, so the water level raised in there, but still no idea....

 

Have this happened to you? Any ideas?

 

Thanks

Easy way to find out. Take out the pump and clean it. I clean mine at least once a month.
