View Full Version : Randy's Two part question for smaller tanks

05/08/2012, 04:39 PM
I am going to be using Randy's two part dosing recipe, (using my home built dosing pumps) and have a question about the 3rd part, the magnesium. Do stick to his original formula and wait until I used up a gallon of the other two solutions (my tank is only 28g so that will be quite a while) and then does the full ammount of magnesium?

Or should I do the math and split it, like 1/4 gallon of the first to solutions and then the adjusted does of magnesium?

Test and add Mg if/when you need to. If you're doing water changes semi-frequently in a small tank the likelihood is that you probably won't need to supplement beyond what's in your salt mix. This could also be true for Ca.
