freezing MTS for substrate enrichment
Hi all. I need soil under the empty space in the foreground of my tank. When I set it up I wanted to keep it open(just sand, no dirt) and have crypts behind it now, I'd rather have crypt grow into it. So, I've heard of people freezing MTS and pushing it under substrate. What is the process for both freezing AND placement once frozen. Thanks.
