GH is at 5d. Enough Calcium I am sure, but I was just going to start giving it a booster each water change. My tap water recently dropped from 7d down to the current 5d, so also want to jump on the game before they change it again, or at least be ready for it.
My Jungle Val has been looking a little weak lately and Ca is the only deficiency that came to mind. I will post some pics tonight to get some more analysis. maybe it is something else!
