We can say this extra filter set-up is effective, so with that in mind would anyone now place their tank by a window. I see the chance to have a tank by a window as a bonus for several reasons. The first is the ability the keep a planted tank with out having to invest too much on light and another major plus I see would be giving your fishes a natural cycle of light that gradually changes for them as it would in the wild making for more natural behaviors. As the tank would go through seasonal changes which we could affect by gradual temp changes by us. So how does everyone feel about these ideas and thoughts.
