This is my 21g Aquatop aquarium. I have 1/2 live, 1/2 dry rock to start. I plan on rearranging the rock shortly. I'm very new at this and really don't know what all I can do to/with this tank to make it better. It has a protein skimmer in back and multi stage filtration (w/ ceramic rings). There was no manual with this and I cannot find anyone here, YouTube or google who has the same tank. Hope all is well! (I can't believe how much money I've spent already and I really don't care.. Enjoying myself so far!)
