I currently have a planted discus tank. A few years ago I had a hystrix and a retic set up I swapped over to the planted discus tank and have regretted it ever since. I love my discus and want to add stingrays with them. I have read on here that some of had luck and others have not. Here’s the questions: 1) with a planted tank I have swimming pool filter sand. Will the swimming pool filter sand be ok? 2) What about the snails?! When I had stingrays before they were constantly pulling up sand and crushing it in there mouths. Do I need to do a full tear down of my tank? I am going to remove the plants and a few pieces of driftwood to make room for the stingrays. Thanks in advance.
