Hey guys this might be kind of a novice question but it's something i'm really interested in knowing to the people who have monster tanks like 300-600 gallons how do you preform a water change on it? Like in my dorm i currently have a 10 gallon a 1.5 and a little tub with a beta in it and to change the water i have around maybe 8-10 gallons worth of empty water containers I take the containers to the shower fill them up with water wait 24-36 hours for the chlorine to evaporate empty out 50% of the water in each tank and replace it with the newer water, next semester i'm moving to a suit and i really want to put a 55 gallon or larger in the common room, I just don't know how I would preform the water change in it would the best bet be should i keep the method i've been doing but keep more empty containers around? I'm just looking for the most efficient method to keep my fish alive especially in the first few weeks of the tank
