I have a 20g freshwater tank that currently houses a number of fish that will soon be moving to a 36g freshwater bowfront. I have a juvenile figure 8 puffer that I am going to be moving to the 20g tank. Currently he is in my 15g freshwater tank as that's what he was in when I got him as well, but I know that F8's ultimately need brackish water, but I'm not sure what to do to get the 20g set up/changed to be ready for the puffer or if I need to change anything currently other than the water. How do i know the correct amount of salt to mix with the water so that it's the correct salinity since i know it's something you have to increase slowly? I have a HOB filter, that should still work right? I know F8's are notoriously messy but it will just be him in the 20g. I'm just feeling a little confused...I've read a bunch of articles and I thought I kind of understood but the more I read the more unsure I feel that I understand and will get things right! I guess I'm just feeling a little nervous and I want to make sure I do everything right for him! I made a list of things I need, can someone tell me if I'm missing anything/if you have recommendations for brands or specific items to get on that list that would be great too!

refractometer/hydrometer (which is better/any suggestions on a specific one?)
