I had a 29g fw community tank for the past year. Last week I empty the water, clean the sides of the tank and filter, except I left the gravel and about 3" inches of water in the tank and I also reused the wood and plastic plants so that there would be plenty of useful bacteria remaining in the tank. I let the tank settle for a day and then introduced two 4" silver Scats that were in fw from the the fishstore. My plan is to do a 20% weekly water change and raise the salinity of tank by .001 each month until it reaches .005. I'd like to hear what others think about my plan. Also, is .005 to high to later add other brackish fish to the tank if they come from fw. The scat are the only fish in the tank.
