Hey Everyone!
I would like some help with my Red Ear Slider turtle. He's about 6 months old now. And about a few months ago his shell started to become this white color and it's not fungus because it's not cottony at all. It seems like discoloration. I then found out the light that came with the tank was not a UV lamp so about more than a month ago i went and got a UV lamp. I turn it on for as long as the sun is up but it doesnt seem to fix the problem. The white is started to get on more scutes and i change the water regularly and i clean it's back with a sponge too. And also i bought this vitamin solution and i soak him in it everytime i change the water and i do have the calcium bricks.
Does anyone know what this is? And what can can i do to fix it?
Thanks!:)
