Hello,
I have a 29 gallon with general petsmart gravel. I kept reading that cory's like a fine substrate so I kept watching them and they would just loose the flakes or pellets in the gravel. Reading everyone talk about sand I thought about giving that a shot.
Is there any good way to change the top layer of gravel over to sand with fish in the tank? I know the sand will be in my filters is that bad for bacteria in there?
I probably will do just alittle at a time not the whole tank or does that matter.
Thanks
