I have kept my nano reef for two years without a skimmer, but I am about to setup my 58 as a dwarf lionfish tank and will surely need a skimmer. My problem however is that I am not very wise when it comes to skimmers since I have never used one. Does anyone have any suggestions on where I should buy from, specific brands to look at, etc? This will be an in sump skimmer and I am not wanting to spend more than $200. Thanks.
