Ok, so I haven't heard a lot about the Oliver Knott Substrate, but I decided to take the plunge anyway and bought it for my recent nano rescape (journal coming soon!). Well, I've just finished the rescape, so thought I'd share my thoughts on it. I really like it! I like the colour and texture, it's extremely similar to ADA Amazonia in that respect. It dosen't leach ammonia though, so it was a great alternative for me. It did raise the GH and KH to 3dkh however, and the pH of the water was 6.6 (I used RO water) about an hour after filling. I'm going to test these again in a while, just out of curiosity. I found it extremely easy to plant in, which was great - it seemed to hold the plants well after the tweezers had been released. I was extremely impressed with the clarity of the water when the tank was being filled-it didn't muddy the water at all! I also found that it didn't disintegrate at all, I'm just hoping that it will stay that way! I found it quite expensive - Â£50 for a 10litre bag from AE, but I'm glad I went with this one in hindsight. The 3 litre bag would have sufficed for my nano however-I've used approximately 3l from the 10l bag, and it's 2" deep in a 12x12" tank. I'll update if anything changes!
