I am using an Eheim 2028 for my new 4 x 1.5 x 2 ft (set up for about 2 months now). At the moment the outlet is a rainbar near the top on the left side panel of my tank. the rainbar directs the output across the length of the tank near the water surface.
I am suspecting that the flow rate in the tank is too high. the water is still not clear and there are always particles floating in the water, i think because the current is stirring up all this stuff from the substrate. the plants (mainly cyprus, not sure if i got the spelling right) on the right (i.e. opposite end to the rainbar) always tilt to the left.
How can i know for sure whether the flow rate is too high?
At the moment I am using the Eheim filter itself to control the rate but I don't really want to do that because the filter rate is only about 3x (I think). Is there a better way of reducing the impact of the outflow without compromising the filter rate?
Many thanks for any suggetions that you may have.
