Hey guys, I have a question about changing the water for these guys. I have one FBT in a 10 gallon with coco substrate. Eventually, I plan on giving him a more aquatic set up, with a piece of dividing acrylic and a water section with its own filter etc. For the moment though, he just has two water bowls I change every morning. One is a small sized ceramic bowl, and the other is one of those fake rock little pools.

I was wondering if simply pouring the old water out and refilling it with the new is enough, or if each time I should thoroughly rinse out the container before refilling it with new water.
