It depends who you ask. In my opinion no. The bacteria grows on hard surfaces such as your filter and media. You can do a 25% WC
. Check your water two hours later and I bet you can hardly tell you did anything. The fact is smaller tanks are volatile and more difficult to cycle no matter what you do. It just takes some time. My fish are happy after a few weeks of this game so I am just going to do some WCs with Prime and not stress it too much.
