I haven't noticed that in myself. I used a mixer for 6 months (before introducing SPS). The pH was 8.1 and the KH remained stable around 8 dKH.
Spencer7805
I observed this along with Denis (Torfish), Nikolai Stochkov (Sleepy), and many other aquarists. This is also mentioned in the thread on "Again about balling":
Quote from Sleepy: "1. Strangely enough, the mixer of hydroxide was pulling carbonates DOWN during balling.
2. The rotors of all pumps started to accumulate algae at an alarming rate.
And most importantly: I see no point in it. You can't really add calcium to it, and my algae scrubber handles phosphates much better.
I also came across something about the incompatibility of the mixer and balling "from the greats"... but I probably won't find it."
Ryan7682
I meant the addition of calcium hydroxide WITHOUT balling. It is clear that if balling is used, there is no point in adding hydroxide! In that case, as was rightly noted, it will be harmful!
Joseph9057
Then everything is correct. With low calcium carbonate needs of the aquarium, the main reaction occurs, and there is enough carbon dioxide in the water, so no precipitation of bicarbonates takes place. The pH is stable during such a reaction. By the way, a powerful algae bloom also contributes to the precipitation of bicarbonate when adding kalkwasser.
Tanya
Why does no one mention that when adding calcium hydroxide and high phosphates, a substitution reaction occurs with the precipitation of poorly soluble calcium phosphate? That is, the phosphate level in the water decreases. How significant is the benefit of calcium hydroxide in this regard?
Sharon
Yes, I agree, we shouldn't forget! It's just that this kind of problem doesn't bother me, that's why I forgot. But again, we precipitate phosphate and lose calcium ions...

Back in 2005, I was using Kalkwasser, introducing many animals (this word doesn't quite fit, but still) into my aquarium... I also had a starfish on ambulacral feet; I don't know if Kalkwasser helped with that. This euphyllia, bought back then, has increased in size about five times over two years! At that time, among the complex corals, I can only highlight it. I did regular water changes, 40 liters every week... So, Stas!!! It is possible to maintain a marine aquarium with Kalkwasser...
Ronald5720
Well, it depends on how to introduce the calquewater. :-)
Keith7534
So I think that if the most demanding of the introduced animals is euphyllia, then calkwasser is just right!!! But if the aquarium is full of SPS, then pouring calk in horse doses will only raise the pH and collapse the alkalinity.
Jacob7201
Well, what if we try to dissolve Kalkwasser in more than a liter of water? Maybe it will be possible to feed SPS with calcium?
Breanna9982
Can boiling water be poured in?
Laura7633
they say vinegar
Timothy
Explain.. Are you talking about this?
Barbara
vinegar...
Jill1815
The solubility of calcium hydroxide decreases with increasing temperature. At 20 degrees, 16.6 grams per liter can be dissolved, while at 100 degrees, only 0.8 grams per liter can be dissolved.
Mario
I won't be able to tell everything accurately, I've only heard... maybe someone knows how to deal with this...
Michelle1662
I added a link to my previous post.
Chad4168
yeah... but haven't tried this!!!
Lindsey3628
Kalquaser is interesting because it can be used without maintenance. Just a couple of times at the beginning to test it. This recipe brings the whole kitchen closer to balling. That is, control - topping up - control.
Brent5588
So what's the point?
I mean, is it suggested to dose calcium acetate into the aquarium?
(CH3COO)2Ca is what is actually produced in the reaction. It all seems questionable...
John3165
The idea is completely absurd. It resembles not balling, but a manual calcium reactor with an accelerated reaction. When reacting with vinegar, both calcium carbonate and calcium hydroxide yield one result - calcium acetate. So why not just soak coral rubble in vinegar - it would be cheaper. Overall, this idea certainly resembles some cosmic nonsense.
Joyce
I don't know, I think vinegar helps dissolve calcium carbonate... but that's just my assumption. I don't know what happens to the pH in this case... maybe someone knows on the forum?!
Frank7213
That's what I'm talking about.
Cindy
The thing is, one of the ways to obtain calcium acetate is through the reaction of acetic acid and calcium oxide (or calcium hydroxide). And calcium acetate has different properties than bicarbonate. Why do we need it?
P.S. Along with the vodka method, there is a method of dosing vinegar in the aquarium, so I wouldn't play around with vinegar.
Jessica8898
Stas, I can imagine how much it stinks from that. I used to pour 4 cubes of vodka. After 5 minutes, the room was already buzzing like from a hangover)) Now I pour rum) - it doesn't smell like alcohol anymore - there's a "taste" of cane added)
Jeffrey6189
By the way, here's what people think about vinegar and acetates.
Amy
I read it. I thought a lot. :-)
Raven7170
By the way, the clearest description of the calcwasser dosing principle I found here:
Loretta5483
I don't really get the point of this post at all. I can't even respond to it.
Janet5447
What is the problem? There is a quote with conclusions, the author's request to correct it, and responses are provided for each of his conclusions.
Heather
I don't know enough chemistry to check, but it seems to me it should be less.
Jill1815
Good job for correcting yourself in time; it's definitely not 8.01. pH is the value of the decimal logarithm. Hence the calculation. In the first approximation, it turns out to be equal to 10. We can ask real experts to calculate it more accurately.
Rachael
It's clear that the logarithm is negative, but it really comes out to around 10. I looked in the textbook on how to calculate it. However, in practice, this is unlikely to be the case. I pour 3 liters of calcium hydroxide into 200 liters of water and haven't observed such pH fluctuations.

A marine aquarium is a complex environment. Numerous reactions occur, including the one I described in the first post of this topic.
