due to a lack of space in my cabinet, i am using a cannister. using a ehiem 2026...... but there is no media or ceramic rings in it. for chemical filtration. in it, i placed chemi-pure, rowaphos, poly filter and filter wool.
i oso utilise a i box for a overflow down to my 1 ft refugium where i grow macroalgae.
still experiencing nitrate levels of abt 25ppm. with the exception of this, so far so good.
