How often should I clean my 3-gallon

[purplemelli]

I have a three gallon tank with an underground filter and one betta in it ( oh and also a heater). How often should I do fifty percent water changes and should I ever clean under the filter and rinse the silk plants?
Thanks,
Melli

I would do a 100% change once a week, and a 50% once a week also. :) When you do the 100% change take everything out and wash it all off.

Wouldn't a 100% change hurt my betta?

No, not if you're careful about it. As long as you use the same water at the same temperature, it'll be fine.

Tanks need 100% changes unless they've been cycled. You can only get away with partial changes in a fully cycled tank.
