I'm new to sand and am starting a planted tank. I put the sand in with soil underneath. I keep noticing dark spots in the sand as I do my cleaning the top quarter inch with this soil being two inches down. I know everything sinks, but are these dark spots a collection of nutrients? Will the sand collect nutrients like this rapidly enough for the plants? 29g lit with dual 40's...
