[C320-list] Black tank additive

[ptormey at 4square.net]

Additives for septic system are generally anaerobic (the bugs live without oxygen) so the additives 'feed' them. The bugs do their thing and the water s returned to nature in the leech field

Boat systems are just storage , oxygenated  with very little decomposition.

BUT I could be wrong 😉
