Filter - power & arrangement - appropriate?
I'm a newbie to the planted aquarium. Need suggestions on the filter setup. Please see the photo. Using Hopar Canister Filter KF-2218, which has 1200 liters/hour output.
My tank: 36 x 14 x 19 inch (90 x 36 x 50 cm) ~40 gallons
1. Is the output of the filter too much for my 40 gallon tank? Is yes, how can I reduce the outflow as there is no knob provided to control it?
2. As you can see in the photo, intake to the filter (right side) is vertical and the filter output into the tank is horizontal . Is this fine?
