Hi guys,
Thor has lived in this tank for more than two years and I've upgraded his home. Now I'm using this tank to grow aquatic plants for Thor to eat. So I'd like to know what's the white stuff build-up on the inside of the tank. If possibly I'd like to prevent it from growing on the inside of his new tank, and know if it's going to harm the plants.
Is it calcium build-up from the water?
Is it turtle quano build-up?
btw, the white stuff mainly "grew" in the opposite corner from where the water filter was and opposite side from where the heater was.
thanks for whatever help you can give!
Todd
