For the first three or for month’s I had my tank I did not have a skimmer, I only had a dual 400 Emperor bio wheel and 2 power heads. I got rid of the bio and just use the skimmer. B/F I did that my paremriter were way off. With just the skimmer it has be just perfect. I have about 70 pounds of lr and about a 2” lsb in a 55gal. I don’t have many anomies and no coral b/c my lighting is no good and I have to up grade some day. I do have a sea cucumber, bicolor blenny, mandarinfish, domino dazzle and a tomato clown and you can’t for get the clean up crew!!
