I have just got a 105us gallon aquarium for Christmas from my parents, which came with a fair bit of equipment and live rock. I'm slowly working through each piece of equipment and working out what each bit does, how it works and how it should fit onto the tank. (proving to be quite a challenge)
So far I know I have:
A large protein skimmer
A jewel filter
2 large and very strong magnets... (does anyone know what they are for?)
Lots of piping
And live rock.
I have just started to set it all up it's looking good already
