I have a betta fish in a very heavily planted 10 gallon tank. As long as the water is good, Can I do a quick 15% water change a week without removing anything and gravel vaccum the substrate bi weekly? What would you guys recommend with a betta? I have sand substrate and 3 nerite snails and plants tied to driftwood so no root feeders. I also just recently added the driftwood with some new plants, do I need to change water more frequently with the new additions?
