Yup i had a doubt that it will work but it worked. I took 4-5 hrs for whole process as my tank was running little low of salt. I only done this with a single molly as u can say for experiment. Now my next step would be to take it to eating. Yesterday it was struggling with flow but now it's ok from yesterday. Will it be ok if i feed it small saltwater pellets? Or should i feed it fw pellets? Also, is it normal f it is not hiding? Also staying at top of the tank most of the time(maybe due to flow)
