Dosing Help Needed

[LeanneP]

My tank has been at 7 dkh for the past week or so and I have had high calcium. My calcium is now back to 410. I have been dosing 3x the amount for alk. I am assuming that I need to start dosing calcium again. My alk has been stuck at 7-7.3. If I have done water changes to try and get my alk up but then it goes back down to around 7 and I was assuming this was happening because of my high calcium. Should I wait until my alk starts to rise more before starting to dose my calcium or start right away? I am not sure if I should be dosing the same amount of calcium to alk right away since it is so much more than I usually dose (3x more), but I am worried if I decrease the amount of alk it will drop below 7 again.
