Right. But the gravel is very large and unsuited for planted tanks. Many of the threads on Onyx will have a warning about that from Rex. The sand, however, is or rather was, about the size of regular Flourite. That's the change that surprised me. I have Onyx sand in my 20 that I set up about 8-9 months ago, and it's only slightly smaller than Flourite. The stuff I saw last night was, I estimate, about 1-2mm. Maybe I'll go buy a bag from them and put the ruler on it. I need some top up anyway.
