I'm so done with Maxi carpets I THINK I have 6 in my tank. I buy them and within 2-3 days they disappear and move to a black hole that exist in my tank. I think they are dead then I see them show up one day and then disappear again. This week the nicest one I have showed up front and center of my tank after being MIA for almost 3 months. I'm hoping it stays in its place. I do weekly WC and really spoil my tank. My friend neglects his tank with no WC for months, no dosing and cheap lights and all his carpets are in the exact spot he put them months ago. Very frustrating from now on if it can move on its own it's not going in my tank.
