1 week old tank- Sand browning drastically
Just as the title says.
Transffered this tank from my uncles a week ago.Over the last couple days, a darkining cover has started and rapidly growing to take over the floor of my tank.
It is concentrated around the heater and back of the tank darker in some areas with other patches suggesting that it is just a matter of time before the whole floor is covered.
What on earth is this?
How do I get rid of it?
How do I prevent it?
Please see pic below and thanks in advance for any help.
