yes I would expect it from a smaller and not so educated store but not this place. They have a large layout and do a lot of tank raised corals and frags. so it seems strange for the to say it's good for his tank.
It's a very old thing to use UGF. And here is some info I got for you. As you can see it leaves no room for upgrading for future. You are pretty much stuck with what you get once you go this route. And the article even said that if you plan on going deeper into the hobby only thing salvageable is the aquarium. I believe it's what it said in the summary.
This UGF is dinosaur age Marine setup... And the list of Cons makes me cringe. I put in BOLD the things that are red flags in my book. its far more trouble to have than anything else...
PROS:
-Cost, entry level investment
-Ease of setup
-Ease to build as a DIY project.
-Low tech or beginner technology
-Little to no additional equipment needed, (this excludes a protein skimmer, which is a 100% recommended part of the setup)
CONS:
-Low available oxygen levels
-Salt creep from the lift tubes
-Detritus trap, (wastes collect in the gravel requiring frequent cleaning).
-Carbon dioxide poisoning, (builds up near the bottom requiring additional airstones to export out of the aquarium causing even more salt creep).
-Low bioload handling
-Prone to NTS, (new tank syndrome)
-No upgrade available to advance to more delicate fish and inverts.
-Non-reef compatible, (fish only)
-Unstable pH requiring constant buffering, (acids and Co-2 build up causing a depression of pH)
-Live rock not recommended with this filter, (not enough O-2 again)
-Frequent water changes to export accumulated nitrates and phenol oils, etc.
