Calicium 400ppm

[In Deep Water]

I tested my water for calcium yesterday for the heck of it and it read 400ppm. Ive never added anything to it. I know this level is pretty decent, but how is my water maintaning this level without ever adding anything?

Probably through your water changes. Especially if you don't have anything in your tank to use the calcium

I guess the only thing would be the small amount of starburst polyps and the snails.
