Left Chamber Water level

Did a 7 gallon water change this past weekend, and now the left pump chamber is at the minimum fill level and the skimmer and right chambers are at max level. This hasn't happened before (used RSM - set up for about 4 months now).

I tried filling the tank by scooping water from the main tank, but it went back down in a minute or so.

Any suggestions?

No problem, when you did the water change a little more water was taken out than put back in.

The sump chamber where the return pump is located will reflect any loss/gain of water in the total system including evaporation.

I would re-check salinity before adding water to bring the return chamber back up to where you want it.

Start a tank thread & share your tank with us so we can follow along, we love pics :dance:

What model RSM? Check you gate height, or look for flow obstruction

are you topping off ro for evaporation?
