I have a couple of questions. One, can anyone suggest a pump, that would pump salt water from my 20G Brute to my tank for a water change? It is about 4 1/2 feet from the bottom of the brute to the top of the tank. Two, I would like to mark the inside of the brute in 1 gallon increments. If I were to use a permanent marker, would I risk contaminates entering the system? Do you have any safer suggestions to achieve this? Thanks.
