Hey guys!
My tank is a 120 with a 20 gallon sump. It's only filtration is the rock, skimmer and some filter wool. I occasionally run carbon too. The skimmer is an Aqua-One G220 Pro-Skim rated for up to 800 litres (211 gallons). The tank hasn't been filled long enough for me to figure out a good water change schedule yet. It was half filled with livestock in it for a few months and only in the last week or so have I filled it the rest of the way and started using the sump and skimmer.
Live stock at the moment is a few small Palaemon Serenus shrimp. There's about 10-20 in there and are all about an inch long or less. A tiny sand goby who's about an inch, maybe even smaller and a smooth toadfish who's about 6 inches long.
I like to feed very heavily. I love big, fat fish who love to eat! I have a few home made foods I feed, most of them consist of chopped seafood, but others have some special extras in them.
This is my collection cup, nice and clean
And this is the skimmer up and running with a beer bottle collection jug thing. Don't really know what to call that lol. I usually use a closed airline tap to block off the drain, but it's been misplaced at the moment lol.
I would like to point out that the skimmer has only just been added to the tank and I haven't tuned it in just yet, I'm getting a much wetter skim than I would like.
