OK. I don't have a sump, so no place to put a sponge filter. However, I do have access to some seeded bio media that I can put in a HOB
filter and some PVC
pieces so the fish can hide and not kill each other. I also have a small heater and a light from another tank. I think I will go with either a 15g or a 20 long, which I will hopefully pick up tomorrow. From what I've been reading, seems like a salinity of 14 ppt is what I'm shooting for. How fast/slow should I lower the salinity from 32 to 14 ppt? Then keep them in there for 30 days to 6 weeks before putting them back into the main tank. I'm also guessing I should gradually up the salinity before they go back in. Does all this sound right?
