Just when I thought I had made upi my mind on Flourite Sand.... I'm planning on a 10g planted community tank with cories included. I like the look of black substrate and heard that Flourite Sand was great for cories but now I'm reading that it's not great for plants. I was planning on a 1" layer ( using one 7kg bag) to prevent gas bubbles ( but I'll still stir weekly) but this won;t be good for plants. I've also read that eco-complete is great for plants but isn't as good for cories, and that a mix of gravel and sand can build up gas/trap debris/mush together so the sand goes on the bottom and gravel on top and can be more dangerous in terms of gas build up...arrrrrrrrrrggggghhhh! I'm going crazy with this decision so, which do you use and what are your experiences with it and bottom-dwellers and plants? Thank you!
