My tank is fairly new. I've got about 3" of flourite under ~1.5" of playsand. I'm looking at the sand now and wondering how I get the poop to mix in to benefit the plants. I've got a clown pleco, and he uses one spot as a bathroom (thankfully behind his driftwood so it's not front and center for viewing); seems to me there's lots of 'fertilizer' in his pile, but how do I get it into the substrate? I've been syphoning it out because it's unsightly and just sitting on top. I'm also worried about the lack of waterflow in the substrate because of the sand. I'm rather tempted, since my tank is new and not really going yet, to remove the sand and replace it with a slightly more gravelly substrate...I'm just not up for an overhaul right now, though. What are my options, and how do I make the poop work for me?
