I Have an external filter Resun AE-806 as well as a coralife skimmer. Is this filter system not good? What is a good filter to buy? I have been running this filter for a year but maybe it is time to get a new one? Should I try running another powerhead? I just tested my water last night and everything was fine.
Does anyone recommend a really good external filter that I could perhaps order from J & L because I am sure they are way more money at Big Al's
