Well....
Here's his recipe and a great article as well!
But, I don't understand your
pH values. ???? it peaks 8 hours later at 2.3??? and it peaks after what? after you've added something?
Your
Alk is way too low. I would suggest striving to get up to 11 or do. Provided your
Ca is at the level that you would like, you can increase just your alkalinity by adding baking soda to the tank, 1tsp at a time over several hours. Keep testing the values in order to make sure that you're not over-shooting
So...your Calcium levels...2.25??? That's a strange number. I also use the Salifert test kit - you should be reading numbers like 800ppm or 1300pm or something like that. Can you re-check?
You don't need to have a calcium reactor in order to run a reef tank. Randy's recipe is basically the same thing as the Balling Method, which is what I have used for the past two years. If you feel intimidated by making up the solutions yourself, you can also just buy CaCl from somewhere like Tropic Marin and dose that along with baking soda (not at the same time). This works as well.
And check out Rob's vidcast on
Kalkwasser. He's made a video of a very simple way to dose your own
Kalkwasser, which is also quite inexpensive. This is a great way to maintain proper Calcium and Alkalinity levels in your tank.
