1. I've kept a successful saltwater reef tank going for around 6 months now using only local tapwater(county, so I'm sure it is treated) with crabs, snails, a shrimp at one time(he was a victim of a bad move
) starfish(well, had a serpent when I had a bigger tank, now that it is smaller I only have microstars) and corals ranging from sps to soft stuff that only really needs clean water and salt. I don't really know what my parameters are at the moment are for hardness or ph(was running around 8 in a buffered salt tank though) Can I use the same stuff for freshwater shrimp without it being treated, or do I need to get some sort of chlorine remover for the water for the smaller tank?2. I've got a little stingray filter that moves 36 gph. Is that enough on a 10 gallon tank? It's internal and the intake is covered in sponge. What sort of media would I have in it? I'm used to saltwater tanks where as long as you've got something that grows bacteria(like LR or sand) you are fine. Even in my freshwater tanks(have 2 planted and 4 natural planted ones) the only filtered ones are the planted ones and those don't have anything except floss in the filter, to let more bacteria grow on it.
