Actually, for 150, you can buy a pretty **** good skimmer. Not an overkill one that most likely costs 300 or something. But there are some really good skimmers out there for 150$. You should look in some of the ads AA has because alot of these sites have good deals on skimmers. I just bought a reef octopus
HOB skimmer. Its got like 4.5 out of 5 stars and i heard from two people already that it really is a great skimmer and gets the job done perfectly. I also got the skimmer for 113$. So im sure with 150$ you can get a really nice upgraded version of the one i bought. The reef octopus skimmers are nice though.. so just look around and you'll be surprised as to what you can find.
And yeah, thominil linked me to that octopus skimmer which was the one i bought lol.
