MY 75g FO tank is about 2 and a half weeks into a cycle, and I've topped it off maybe 3 or 4 times. I've been putting some of my tap water into a bucket, adding a teaspoon of stress coat, and letting it sit overnight so it can come up in temp and aerate. Is this all I need to do? Should I add a heater? Should I use stress coat to purify the water, it is supposed to neutralize, chloramines and chlorine? My real concern is water changes, how do most people go about prepping their water for water changes. I don't have room to put a garbage can full of water in my house, so what are my options??
