Hi Krish,
Saw in a recent post you mention using white pvc board for the bottom of your BB tank. What exactly do you use? I got rid of all my sand due to not being able to clean it well enough, but the bottom of my tank looks like hell. I'm thinking about putting something down to cover the bottom, and your PVC comment sounded interesting. And if there are any other similar ideas you've come across in threads, please let me know.
Thanks, Marc
