i have a 2 year old freshwater tank that i am turning into a brackish tank. bought a small heater, water circulator and bucket to mix marine salt into water to prep for the tank. i purchased a F8 puffer that is supposed to be in brackish water and i will receive him tuesday. i was told just to mix the marine salt into 3-4 gallons enough for the 20 gallon tank 24 hrs in advance. then remove some of the my old water and mix in the 3-4 gallons of new salted water. is that correct? how much in advance should i do this prior to putting my new puffer in it?
also cant seem to figure out how to put together the pump to circulate the water in the bucket. uhg

You can only safely raise the SG by .002 a week, our you'll destroy your bio filter. You have to have a hydrometer to measure your salt water level. If your total volume is 20 gallons subtract a few gallons for substrate and decor displacement, and you will need to know the exact amount for your exchange water. So if 4 gallons, then add salt to raise it to the desired amount using this calculator http://www.hamzasreef.com/Contents/Calc ... linity.php
