Hi Forumers,

I am thinking of getting a wave maker to help in CO2 circulation for my 422 planted tank.

I saw a Hydro nano and a Hydro 1. The nano has capacity for 900l/hr (for up to 100l tank) whilst that of the Hydro 1 is 1,500l/hr (up to 180l tank). Which is more suitable for a planted tank? I have seen forumers selling high-powered ones to make way for nanos.

I have an internal CO2 reactor. Where should I place the wave maker?

Appreciate any advice, please.
