I guess my concern (and it's obviously not the case for you) is that if I do it over a 2 week period, doesn't that increase the chance that the new sand may become seeded with Dinos over the course of that time? I have an order for pods and phytoplankton on the way from Algae Barn. That should help. This my burning question. Could I do the whole change safely over the course of a day with bacteria supplements. I don't want to rush and put the whole tank at risk. But I also don't want to seed new sand with dinos.
