I have a 3 gallon tank and so far I have been doing 100% water changes once a week and acclimating the fish to the new water slowly before putting him back in.
My question is could I do partial water changes using a gravel vac instead of the full 100% and if so how much and how often is recommended?
At first I was considering cycling the 3 gallon tank, but upon further research I decided against it.
Is it possible to do partial water changes and still have good water quality in a 3 gallon tank? And would I need a filter?
Thanks in advance to anyone who responds
