Really must test for Nitrite and Nitrate. Nitrite is even more toxic than Ammonia. Water clarity has not much to do with water quality, it's a non factor actually. Are you using a liquid test kit? Strips are not accurate. I would pick up a Freshwater API Liquid Test kit, it's incredibly useful and well worth having.

My water out of the tap is pretty hard. And I hear these guys like hard water.
The waters they hail from in Africa are hard, I've also read for optimal health, hard and basic (alkaline) water is best. That being said Xenopus are incredibly adaptable and do fine in a pH of 6.5 to 7.5.

In the past 2 weeks I have done several major water changes whilst getting the rocks out of there. And I have an Eclipse system that I have changed the media out of 3x since I got the frogs mostly since there was a lot of debris kicked up getting the gravel out of there.
Water changes are good but too many could mess the cycling process up (or at the very least retard the process), were you cycling this aquarium? It's very rough on frogs if so, they are very sensitive to Ammonia/Nitrite.

Also when you said you changed out the media, that right there is not good. The filter media is actually where the vast majority of your beneficial bacteria propagate; that is the bacteria that breaks down your highly toxic Ammonia/Nitrite into a much safer Nitrate. You actually want to almost never replace filter media, the only reason the instructions say to replace it is because the company makes money if you do.. you actually just want to take the filter media and rinse it off in a bucket of aquarium water and then place it back in the filter. Replacing this media is basically restarting your cycling process, not good!

In any case, here are 2 pics. I hope they are clear enough. I took them thru a zip lock bag I had put him in.
I've never had a frog with red leg, but that looks like red leg. If anyone else would like to chime please do but that does look like a bacterial infection. :/

Sorry he did not make it. I think getting your aquariums nitrogen cycle established is going to be key in ensuring your other frog survives.
