PH at 8.0

[exnisstech]

Your PH jumped just from adding a skimmer? Did you run air from outside to accomplish that?

I’d consider just running mine at night, that might be a good compromise?

I got the bump just adding the skimmer. I did run an airline outside the other day because the house is closed up now.

FWIW, here was the pH of my SPS frag tank 15 minutes ago, and then again after the addition of a few ml of 2 part. I normally don’t add this much at a time I just want to demonstrate how much of a boost it will give your pH. I’m dosing 180 ml of 2 part every 24 hours. I run the skimmer 24/7 but I do not have an outside source of air, and I have extreme surface agitation. In the morning at 7am when the lights come on my pH is usually 8.05 or so. The only way to drive my pH higher at this point is to use kalk, but I don't have huge evaporation so I'd have to add it to the ATO and I don't like the solidified mess it leaves there so I don't use it, tried it and saw no appreciable coral growth so I stopped.

In the OPs tank, alk consumption of only 0.1 a day isn't much so any dosing you'll do is going to be minimal. With your volume of water you may find kalk to be the easiest way to boost your pH, I didn't find it to be beneficial but every tank and scenario is different. Update your thread after a while and let us know what is working for you, these things are good to know.

My ATO isn’t super accessible and I’m gone 3-4 days a week so kalk in the ATO is too much of a fail point for me to consider

Ok. I might give this a shot but I think I have a few other things to remedy first. I have a crappy bubble magus with a AC pump that hums louder than I can stand lol.

I hear you on that lol. I used a modded DC pump for my skimmer and now it's silent.

The point of information I am trying to convey is:

Titration is a means of measurement to establish a known pH, through the addition of an acid.

Carbonate Hardness is a prediction of the availability of a carbonic anion.(carbonate;CO3 2-:Bicarbonate;HCO3 -; or Carbonic Acid; H2CO3)

pH(potential of Hydrogen) rather is the logarithmic scale of ionic hydrogen and Hydroxide. It fluctuates in closed systems as a result of periodic changes of the availability of oxygen(due to photosynthesis) Decreases in nighttime hours are caused by the respiration of all flora and fauna.

In natural systems pH is stable due to volumetric conservation rather then local variation from diurnal/nocturnal consideration.

Although Kalkwasser has been used for decades to supply both Calcium and Carbonate demand in closed system. Regulation of pH, by means of Calcium Hydroxide is unreliable.

Some of what you wrote is incorrect or misleading (such as the effect of O2 on pH, of which there is no direct effect), but you are writing these chemistry facts as if it has some import to the use of kalk, which I don’t see how it does.

The last sentence on pH boosting with kalk being unreliable has the potential to be very misleading, depending on what is meant by unreliable.

You may have meant the words below as a reply rather than as a report post link, but I’ll copy them here for your convenience. I don’t think what you are getting at is accurate, or at least it’s not a concern for reefers as best I can understand.


Consideration of hydroxide presence and the ionic structure as present as a carbonate or bicarbonate is not shown by acidic titration. Yes the carbonic molecule is due to the presence of carbon dioxide or a carbonate mineral. Also true is the fact that hydroxide will show as the potential for carbonate in the absence of carbon dioxide or carbonate makes mineral.

The original post is considering the addition of Calcium Hydroxide to elevate pH. The pH,as known, is the logarithmic potential of Hydrogen.
The presence of a carbonate is not necessarily determined by the addition of hydroxide or the various anions it my transcription too.

Finally all hydroxide are caustic and present dangers for chemical and thermal burns

just use a decent dosing pump to control the amount you want to add. No idea why people even consider the inconsistency and mess of adding kalk through their ato.

I’m curious if I could find a dc pump that would work on it. Thankfully my wife bless her heart says the sound doesn’t bother her but it certainly bugs me

That’s certainly a consideration. I’m currently retail fasting this pay period lol. I need a few other things currently and I’m hoping to get my system a little more in line for the next order of frags. Also have a 20 long that just got wet because I thrive on chaos lol
