If you guess, you fail. Ive been there. I later dumped forty pounds of black quartz into a twenty-gallon tank because it "looked right." Within a week, my birds were suffocating. The bottom of the tank looked later than a lunar wasteland. It was a disaster. To avoid my mistakes, you must learn to calculate substrate for aquarium needs properly from the start. Finding the ideal sharpness of sand isnt just virtually looking pretty. Its very nearly biology. Its very nearly not letting your fish tank size calculator rouse in a swamp of their own waste.
