wow that must of been fun! salt, fresh? lake, ocean? photo? 😄
A glass carboys was one of my ideas, but expensive, made of glass and i'm not sure how i'll get a filter in there. With all the options for cheap clear plastic storage boxes these days, i was just going to strap it down like an atomic boom and position it for least momentum. You are right about liquid in a round container being easier to manage but i'll see my options test it first. if not an old water plastic jug shouldn't be too hard to find, but only 5g 😞
just a few more questions
what did you keep? for how long? did any of them die? do you think they liked being in sail boat and in such a container? did you use lake water for water change? lights? planted?
