Well cleaning the gravel has been getting harder. I was thinking of sand but I'm not sure if that will be even worse. Would taking the gravel out and leaving it bare bottom affect it? I have a peacock and TT eel but the only one who uses the gravel to hide is peacock so I'm thinking to get some PVC pipes on top of the DW I have. Anybody had this problem? Or have any advice?
