20g newbie

[troni]

Welcome! I'm pretty new myself, and from what I've seen your other 90s will become salt soon enough. I also have a 20g, just a heads up after your cycle is done you will get brown algae break out and some green hair algae I've read is normal.

There's a lot of debate over skimming a small tank. If you can I would. First thing i'd suggest is a sump. It'll hide everything plus you can put in a refuge aswell. Looks a lot cleaner.
