How Much Circulation For Tropicals

[STD]

I have just converted my Juwel Delta 300 (270l) back from Marines to Tropical

The circulation and filtration is provided by an Oceanrunner 3500 (3500 l/h) in the sump (filled with ceramic rings)

Is this enough circulation and filtration?

depends what your keeping some fish come from still pools some from fast flowing rivers

give us an idea of what your keeping

In general, it should be fine. The recommended amount seems to be in the 1 tank volume per 6 minutes, give or take (nothing in fishkeeping seems to be gospel).

If your fish species don't like high flow, just angle the returns into the tank sides.
