So here's my dilemma. I started with pfs, then found that my giraffe nose catfish loves to dig and sift through it. Too much sand was getting sucked into my filters so I vacuumed all the sand out and went bare bottom for a while. I have ceramic tiles on the bottom now but I really miss the look of sand and the ease of maintenance. Can anyone recommend a coarse, sandy substrate for me that won't be as fine as pfs?
