Alright so I know that at the least I have a hard water problem, but also the top of my turtle has tiny white spots, not scaly, not fungus looking, it looks like its the shell just a different color, can they naturally have white spots? Or is it shell rot or something else that needs to be dealt with, the water is changed once a week (cold water, thats heated to 75f) and I have a 50g filter in a 30g tank.
Also is there a way to remove the hard water stains? I know it doesn't hurt him, but doesn't let the little guy have his lustery shell. I have tried warm water and a soft brush, but thats it.
Oh and the turtle seems to be very happy, swims all over the place, gladly eats, and makes a mess lol, likes to bask for awhile, skin and face are great, but i am at a loss with the shell
