75g water level

[Trenton0115]

I’m a complete noob with this tank. It’s a 75g AIO and runs to a 10g manifold with reactors. I’m having trouble figuring out what a good water level is for my back chamber. Do I want the water level just under the baffles so the pump pulls water over them better? It’s currently about an inch or more above the baffles and looks like water sits pretty stagnant. I just feel like I have it too full.

higher, your back chamber are basically mini tanks, you should treat the water levels in them like how you would treat your dt's water level
imo

In my AIO's I have the water cascading from section to section in the back. This helps with gas exchange, and prevent any film from forming on the water in the back section.
