I have a 75 gallon tank that I do a water change of 35 gallons every week or two. However, I know my water bill is probably going to suck because of it in the future...
I had heard a fishkeeper on another forum say that he/she did water changes to his/her tank by taking out the necessary amount of water, "cleaning" and "buffing" it and then putting the water back into the tank as "new" water.
Is it safe to do? And if so, what would I need to use in order to re-new the water?
