    Hydor Nano Circulation Pump-on for 24 hrs

    I have a 200L aquarium filtered by an Aquamanta 300, this supposedly turns over 1100 lph, but obviously somewhat less in the real world. Water movement in my tank is OK, but hardly spectacular. CO2 and aquasoil base. I have ordered a Hydor Nano that turns over 900 lph to move things about a bit...
