Replacing lost water

[ElectricBlueSeanBurch]

Confession time, I have a 15g column tank setup with 20lbs of live rock and 2 small fish. Well I've been focusing on my new 225g setup and neglected my little tank. Fish are still fat, happy and healthy...the tank is just down about 3 gallons. What is the safest way to get it back up to full? I'm just worried because the tank is so small and I know the fish are sensitive to changes in chemistry. Thanks,
Josh

Test to see what your salinity is.

I would test to see what your salinity is. If the water level is that low your salinity is pretty high. I would add a half gallon a day of fresh water or so

I need a new hydrometer. I guess that's the 1st step

Put 3 gallons of water in a bucket and very slowly drip it into the tank (almost like you are acclimating a new fish). This will gradually decrease the salinity of the water and not have an abrupt affect on the fish.

This is what I was thinking. I Have a drip setup to use. I will just do it my next day off. Just wanted to make sure I wasn't crazy

It is hard to be to crazy when keeping fish .
