FYI in case anyone else is having issues with water levels after using inTank media basket in chamber 1. My water level in all the chambers was very low and the display water level was very high and no matter what I did, I couldnt get it to level out. So I cut out about a half inch off the top of the inTank basket, where the water flows into it from the display so it lines up better with the bottom of the holes where water enters, then cut off the tabs on the plastic skimming plate so it sits lower. Now water flows into chamber 1 and the inTank basket a little lower from the display tank and my water levels are now how they should be.
