Extra pump for water flow

Trout can't sit - euh, swim - still

Saro installed an extra pump with no hose attached to it to generate extra flow in the water.

We have both perch and trout in the same tank and if you observe them for a while, you'll see the perch hanging very still in the water, while the trout always wiggle their tail. They're built for swimming in streams.
