Looking for some sand. The fish or whatever has caused the sand in front to go back so its bare. Looking to fill in the front gap. Let me know what you have before I go buy it.
Bob, appreciate the advice but my pumps are not causing the sand to blow back.My "bare spots" are caused by currents from high flow return pumps and powerheads which are typically directed at the front of the tank. You might consider directing such pumps to aim at the water surface in your tank to see if it makes any difference.
