So Master Betta is all set up and very happy! How often should I clean his tank? I do have one of those vacuum hose things to suck to doo doo out of the rocks. Should I do 100% changes, 50% 25%? How often? Thanks!
Then you'll want to do 100% W/C about every 6 days. Be sure to clean the gravel well and match the temperature of the new water before refilling. In a 'cycled' tank, nitrifying bacteria reduce a toxin in fish waste called ammonia to a far less harmful compound which only requires weekly 25% changes to manage.
The only issue you'd have with a filter is a round bowl and a rectangular filter don't mix.
I think it would be easier to do 100% PWCs once a week.
I do 75% PWCS twice a week along with scrubbing all the ornaments in my negative 1 gallon critter keeper that Theodore is in. I'll actually be preforming one tonight.
