Ok I think I understand what to do, I'll have to get a couple more buckets or something if I need to let it sit for a couple day's first. I only have one bucket and usually when I do water changes I use 2 1/2-3 buckets full but I am overstocked right now and am doing water changes every 2 day's and bigger ones just to maintain the nitRites and niTrates and ammonia levels, once they are moved to the bigger tank, I (hopefully) will only be doing 1/week, but with the BW tank until I get it to the salinity level I need I'll need something else for it (I think) do you think 2 buckets a week would be good, that would only be about a 10% change each week though. If I'm going slow with the salinity would that work or should I do more like a 20%?
