Micro bubbles when feeding

[Heliarc19]

I got a new varios dc return pump and have been using the pause"feed" function when feeding , when it comes back on it blows micro bubbles in DT and I was hoping someone had a remedy. They go away but it takes over an hour and is very annoying to look at.

hmm you could try and turn the flow down so you get a barely noticeable trickle through the return.. thats what the vectra does..
