My 40 gallon tank is 4 months old. I have noticed recently that the top part of the sand is turning quite brown in some places. You can really notice it when the Pistol Shrimp does some digging and the sand from deeper in the tank is so much whiter in comparison. It is not the red slime of cyanobacteria...been there...done that.
Any idea what may be causing this? I have about 15x water flow in the tank with the 2 powerheads and the skimmer. Could I need more water flow??
Any idea how I can clean it up some...it is looking a little "ghetto" in my otherwise immaculate tank. I was wondering if perhaps a cucumber or something could help clean things up a bit.
Thanks
