My boyfriend and myself have had our 2 baby RES for almost 4 months now. We take some of the water out, and put new water in once a week. Twice a month, we take the filter, heater, floating rock,fake plant (to help them hide on the rock), and the tank and we clean them. We keep the turtles in a separate container while we do this, and the process is usually an hour or a little more.
My question is, is this ok? I see some people on here saying that you shouldn't clean the filter unless it gets plugged, and not to clean everything at once because of certain bacteria growing. I am uncertain of what we are supposed to do. The last thing we want to do is hurt them, but we think by cleaning everything, it gives the turtles a better life. We notice when everything gets really dirty, including the water, they are more sluggish, and as soon as we clean everything, and they get put back in the tank, they are swimming and seem more active.
So are we hurting them by cleaning everything at once, or are we doing the right thing?
