Hello, everyone! I bought my betta little irresponsibly, but within two weeks of buying him, he had a 3 gallon heated, filtered palace with adequate water changes. However, substrate cleaning never popped into my mind!
What I've been doing is using just a bit of small tubing every few days and getting out a lot of the crud, because I don't have anything more powerful to use. Is that adequate or do I need to go buy something more efficient? Thank you so much!
