Help with water change.

[Nick Steele]

Is this drastic of a difference in calc anything to be worried about before I do my water change? Or should I just wait to change water since parameters aren’t bad.

Tanks 2 months old and most things are doing good. Have slight problems with a bleaching monti spongodes and candy cane that got gha and hasn’t recovered yet.


Tank
Alk 10.7
Ph 7.7
Calc 420
Mag 1200
Phos 0
Nitrate 5

New water
Alk 10.2
Ph 8
Calc 480
Mag 1230
Phos 0
Nitrate 0

I don't think it is.

Just as long as your Alk is between range you should be just fine.

Calcium should not be an issue. In my opinion big swings in Alk and Salinity are big bleachers and killers.
