I posted this in my build thread but I would like some help with it if I can.
So I am trying to get a handle on dosing calcium and alkalinity. For 14 days I have dosed Seachem Reef Fusion 2 part. I do half the recommended dose, dosing both parts in the sump return chamber. Part 1, wait a few minutes and then part two. I started dosing both parts after the weekly test two weeks ago showed a drop in calcium and magnesium for the first time after a water change. Last week's test showed a rise in these after dosing daily for a week. Today is water change day so I tested the new saltwater and the tank's water. I think I am on the right track but I would love some feed back from people who understand this better than I do.
January 15 (before dosing both parts)
Alkalinity 9.8 dKH Red Sea (this I had been dosing daily for a while)
Calcium 400 ppm Red Sea
Magnesium 1400 ppm Red Sea
January 22
Alkalinity 9.8 dKH Red Sea
Calcium 420 ppm Red Sea
Magnesium 1440 ppm Red Sea
Today New saltwater using Instant Ocean Reef Crystals.
Alkalinity 10.9 dKH Red Sea
Calcium 450 ppm Red Sea
Magnesium 1520 ppm Red Sea
Today's tank water before water change.
Alkalinity 10.1 dKH Red Sea
Calcium 430 ppm Red Sea
Magnesium 1440 ppm Red Sea
I have kept a chart documenting my weekly tests for the past few months if that helps.
Also, should I dose on water change day and if I do, should I do it before or after I change the water? And how long do I need to wait after the water change before I can test to see what the water change has done to these numbers?
