Hi having kept FW fish for a while i'm looking to convert one of my tanks to a brackish setup. Could i take an already cycled FW tank and slowly increase its salinity to turn it into a brackish tank? If so which is the best salt product to use, what sort of time period should i be looking at converting it over. Also (sorry about all the questions) i was thinking of using mollies to keep the tank cycled what do you think?
thanks
thanks
