We (SO and I) have two ~2" Red Eared Sliders that I recently moved from a plastic storage bin to a proper 20 gallon tank. Previously we didn't have a filter, we just dumped out the water and scrubbed the sides when it started getting murky. With the new tank though, the weight of it makes that a lot less convenient. I have a filter on the way, but I know that regularly changing water is still required.
What's the best way to change the tank's water? With your setup, do you ever actually move the tank to dump it out, or do you do everything with a siphon, for example?
The other problem is that I don't currently have any furniture to put the tank on. I know that siphons tend to need to have the tank elevated above the water receptacle in order to work, so that's a problem. In getting furniture to put it on, should I get something with wheels so that I can easily move the tank back and forth between the bathtub (I live in an apartment) for the purpose of emptying it?
