Old tank questions?
Hi, I'm new here but not new to betta's.
So I have a little story and need some help. My family's betta of over 4 years passed away. he was healthy and lived happily. This devastated (at the time) my 4 year old daughter. She still brings up Buddy (his name) to this day. She is now 6yrs. She decided she wanted a new friend for the family. My problem is that I can't remember if i cleaned Buddy's tank after he died. It has been about 2yrs. Even so, i still would clean it no matter what, but how should i clean the tank? Should I use 50/50 vinegar and soap with warm/hot water, or is there a better way to clean an old tank that may or may have not been cleaned?
The tank is 10 gal. Also, the filtration system, would you clean that the same way as the tank? Thanks!
