ATM Colony & Paradigm 16oz/473ml Marine Bacteria/DechlorinatorAquarium cycling, or the process of establishing bio filtration for natural ammonia and nitrite removal, has been a long running issue in the aquatics hobby.

Simple, straight forward all black polo. I am a size medium woman (with some room since I don't like form-fitting) and bought a men's small. Fits perfectly for my frame. Long enough to tuck in for my part-time extra weekend job uniform. Also suitable for the golf course. A little thin, and if you hold it up to light you can sort of see through it. *Not* flowy, soft and smooth fabric like a rash guard/sun shirt - more structured than that. But it's cool and does the job for the price under $10.
