Hi I’m new to the forum. I have had an aquarium for a few years and currently have 3 up and going. The aquarium in question is a 55 gallon and it is planted. I’m new to the planted aquarium as I’ve only had plants for a few months now. I’ve noticed little white spots and I’ve been trying to identify them without luck. This morning I saw them in my gravel so was able to get a decent pic. I do have hard water so I’m not sure if that has anything to do with these spots.
