Shade Posted October 7, 2020 Share Posted October 7, 2020 Will my Flourite absorb any of the nutrients leeched from my soul. I set up a rubbermaid 50G tub to grow out some Crypts and I thought that a dirted tank would be the easiest to grow the plants and wanted to use Flourite Sand for the added iron. I have ~1"+ of soil with a top of pool filter sand x Flourite black sand 2"+ deep. I thought that some of the nutrients leeching from the soil might get caught in the Flourite (bc of the CEC) but I wanted to know if it is true at all or if it is so minimal that it would not make a difference. Thank you all in advance. Link to comment Share on other sites More sharing options...
