All the talk of skimmers and I almost forgot to show off the beast on my frag tank. I had an reef octopus but I gave it to my dad, he didn’t have the funds for one. I was given this one still brand new in the box sitting in a garage for no telling how many years. I decided I would give it a shot since frag tank is usually low nutrients anyways. It’s an old coralife skimmer, supposed to be rated for up to 220 gallons but I doubt that. It’s loud but seems to be doing ok.
