Red sea foundation ABC

[JVan82]

So I picked these up plus reef energy A and B. So Sunday after a water change I did test for cal, kh, and mag. Cal was 450, kh was 9.2, and mag was 1240.

Per the bottles I needed to add 110ml of mag and 26ml of kh. But the directions state not to add not than 10ppm mag and 1.4dkh. So how do I add 110ml of mag if I can only add 10ml of mag, and 14ml of kh daily.

Also using Red sea test kits as well...

You can add up to 100 ppm of magnesium in one day, although I'd probably break that into two doses, just because calculators require guesses about the actual water volume. If the dKH is 9.2, that's already fine, and I wouldn't raise it over 11 dKH. Adding 2-3 dKH at one shot is fine for soft corals and coralline algae. What's in the system?

What's in the system?I have 2 hammers, 4 zoa, 4 favia (3 frags), 2 sps frags, an acan frag, and an torch frag.

Since I have a small system (biocube 32) was going to add 10ml mag multiple times daily. And I'll just leave kh alone.

Dosing multiple times per day is fine, but 50 ppm for magnesium in one shot is safe, too. I'd avoid big alkalinity changes with stony corals in the tank.

That sounds like a good plan to me. :)

That sounds like a good plan to me. :)Hoping my hammers will grow finally!
