What is the best bed depth for this stuff? Setting up the tank, but I haven't filled it yet. What's the best depth? If it matters, it is a ten gallon tank for CRS, and I want it to be able to keep the pH at 6.5 or so.

Thanks!

I use the whole 9L bag for a 10 gallon. It makes about 3.5" of flat substrate. It should last me more than a year. I'm hoping for two years with strictly 100% RO water. But to be honest 3.5" of substrate on a 10 gallon looks too thick. Plus it displace so many gallons of water. With 3.5" of substrate, my 10 gallon tank can only hold about 7 gallon of water. I usually do 1.5" - 2" max of flat substrate.
