I like laterite....just mix it into the lower third of the substrate. You can add a bit of peat and mulm to the bottom layer, throw down some sand/laterite or gravel/laterite, and cap it with an inch or two of sand or gravel. You will probably have to tear down the tank to do this though.

You could also use flourite or any of the other commercial substrates as well. I just like the laterite combo because its so cheap!

You can order it online, Bigalsonline is pretty cheap. You can also find it at your LFS or probably have them order it for you.

Dont throw away your MTS! Save as many as you can. You only need a few to start a thriving colony again though.

I have never had any trouble with laterite clouding the water, although i keep a cap of about two inches in my tanks.....
