I saw your design quite a while back, and I wondered if it would work OK with just an airlift?
Someone once told me that in hydroponics the roots should be allowed to dry out a bit between waterings.
I don't do this, but I'm thinking more air will help the roots.
For a while I ran two systems with the Pothos in a remote planter, and just circulated the water to it with an airlift.

I had to keep the drain free of roots and leaves though, or the planter could fill 100% and overflow.
If it filled up all the way, it put too much weight on the lids and tank brace, so I had to put some sticks under the planter for support.
Those systems are both gone now, but they worked OK and nitrates were reduced.
