So I did it. Cleared out the gravel yesterday, ended up being about a 50% water change, put in the sand today. Stable parameters, but I added purigen to try to clear the water from everything only to realize the damn bag had a hole in it, so now there’s purigen balls scattered all over the new sand. Should I be concerned about the cories eating them? There’s no decor or plants in the tank for now, sitting in buckets of dechlorinated water and I can barely see enough to attempt a sand vac. Any suggestions are appreciated.
