Yes i know another substrate question. For my new build im planning on using a substrate that looks like Zeovit KZ Substrate. Its from Natures Ocean and it is 2-3.5mm in size. Here is the link: Alternative Zeo KZ Substrate Im having issues with sand blowing around in my old system due to high flow and was wondering if anyone used this substrate before and what are your thoughts? If not this substrate, what do you recommend? Or if you know somewhere i can get the Zeo KZ Substrate here in the US? Thanks in advance.
