• The ratio of Ca <-> KN

  • Joseph9203

The aquarium maintains a consistently high KH of 12-15. I measured it today - 14. Calcium - 360, magnesium - 940. The test is from JBL. I found a table that says I need to raise the calcium to 460. On Monday, I think I'll stop by the pharmacy (they prepare solutions) and ask about calcium chloride, magnesium chloride, and magnesium sulfate for adjusting the levels. Should I adjust them, or will they normalize on their own?

will start to fall kN... in practice, it is difficult to achieve balance this way. Calcium will precipitate in the form of calcium carbonate.

As of today, KN-14, Ca-460, Mg-1240. I adjusted with Calcium chloride and Magnesium sulfate. KN could still be lowered...

If you need to "quickly" raise calcium (360-380) - is calcium chloride available at any pharmacy? What potential pitfalls could there be in this case? Additional Info: Before the water change, calcium was 360. In fresh water, it was 380 (1.022, T27). The next day, I changed 30 liters. Control measurement - calcium 250. This is absurd. The test is probably dead.

250 is definitely madness, and complete at that. I wouldn't rush with the chloride for now. It needs to be double-checked with another test. I always have 2 tests for calcium, currently Salifert and Tropic Marin. (I prefer Tropic Marin more.)

Yarik, the test is shining...

Offtopic. You really need at least one acropora in the household. Otherwise, the seriatores are a bit inert, but the acro would immediately signal its well-being.

Joyce

How can you tell by the acre that there is a calcium deficiency?

Danny

Offtopic: J.K. and SPSs dissolve.

Appearance, growth points, delaminations.

What are detachments?????

I don't know about the acre, but regarding the aquarium - if there is a slight film on the glass at the waterline, it means there is enough calcium. It's a sign.

It is generally difficult to determine a deficiency of potassium or calcium in acropora. They simply stop growing (and for a long time). It is much easier to visually see the imbalance in seriatopora (the growth tips do not become as white).

Justin

Offtopic I have seen problems in the tanks due to calcium from photos, not in person. They were peeling off - as if the living tissue was separating from the main part of the coral. (But maybe this is for other reasons - I didn't read the translation carefully.) Regarding growth points, +1. As for the Seriatopora, it seems to me that there is a rather prolonged reaction period (up to a week) - after the water change, the growth points "elongate," while in the old water they "shorten."

Good afternoon. Today I measured the CN and Ca. Ca-410, CN-11.5. Could you please tell me if such an imbalance is critical? If so, how can I reduce the imbalance? I am using TM balling, Salit tests.

Tanner

pour more calcium. clearly, there is a lot of hydroxide being poured

Emma

I pour the same amount of all solutions, but KOH just skyrocketed, while the calcium content is increasing slowly. I will then only pour solution A (CaCl2) and salt without salt for now.

Brian6895

In this case, do not add salt without salt. Only add calcium until the KH drops to 7 and the calcium rises to 450, and then add all three solutions in equal doses.
