ACI Kalkwasser Method.... I've watched this video and read a few articles, still not sure the exact method.

[Garf]

Presumably he (C.M.) doesn't ship out corals in 13.3DKH water, and these are seperate systems, its a bit confusing. In the vid with Chris Woods, C.M. actually mentioned "mature systems" for the first time I can recall, and I've watched a lot of his guest appearances.

Take any claims from Chris with a major grain of salt. Every questionable chemistry related claim he has made has been checked by true chemists and proven totally false. Less than a year ago he claimed you needed to use a special 4 ingredient alkalinity supplement or you'd never have consistent alkalinity in your system.

I asked Randy about it and Randy scientifically shut it down in less than a couple minutes.

pH is extremely important and completely overlooked within the hobby but dumping in a ton of kalk every night isn't the fix for 99% of tanks.

I started

 

[henry89]

I started 3 days ago using his Neptune and Neptune doser rule slowly raising day by day of average ph daily until I reached 3.0
. ( IF PH > 2.9 then off ) and man it’s working prefect

captive 8 kalk
6.5 g per gallon
Doubled my evaporation
Used Neptune doser tule

I presume you mean pH 8.3 not 3.0.

Are you monitoring alkalinity?

Yes sorry lol 8.3 alkalinity is raising i was at 8 and now at 11 but I see my sps polyps witch I’ve never seen it’s amazing. A bit scared about the alkalinity but doing a water change today so it will bring it down a bit .

Couldn’t you just use the sodium hydroxide 2-part by Randy and a CO2 scrubber on a skimmer to achieve consistently high, relatively stable pH and stable Alk?
I don’t think you can feasibly ask for more than that in a home aquarium.

Done it nothing maybe 7.7 up to 7.9 but that’s it

You are using sodium hydroxide two part and it’s done nothing?
In that case Kalk is gonna do nothing either because its pH boost per unit of alkalinity is the same as sodium hydroxide.

I’m not sure I’m just using captive8 kalk on a Neptune doser . This is my ph as I type

Yes I was using two part but ph will go up but not to the number I want 8.3 also But I noticed I’m always dosing alkalinity and calcium constantly and everything was stabled but ph wouldn’t go higher than 8.0

Dosing kalkwasser using Chris method it’s working perfect . My ph 8.3 most of all day and now my calcium super stables and alk rised a bit without dosing two part .Super happy with parameters and ph noticed in 4 days literally poly extension on 80% of my acros

Are you measuring Alkalinity at lights out, or in the morning? Alk should be greatest in the morning using this method. I’m using kalk but still add more of it during the day than night, to reduce the swing. I still haven’t wrapped my head around why, when I tried this method (well a watered down version) last year, everything went pear shaped, I seem to be one of the only peeps to have reported a problem. It’s not beyond the realms of possibility that a coincidence occurred but for the life of me, I don’t know what else could have caused my issue. All issues stopped immediately after letting Alk reduce.

[henry89]

This is my alk 24 hours also ph .. u can see my ph stabled all day until lights are off 9pm. alk is up and down with out me dosing no two part just kalkwasser. I was scared with this alk level but I’m just amazed in results in all my corals growth and color also sps polyp extensions , so I’m just going with what Chris said in his video if corals looks happy just go with the flow

I believe RHF has stated that while the pH boost is the same per unit of alkalinity, the time between doses with sodium hydroxide does not allow as high of a sustained pH as using kalk.

I have observed this through personal experience.

Can you be more specific?
are you saying that pH fluctuates more with sodium hydroxide because it can’t be dosed “drop by drop” like kalk?

that's not much of an alk spike, looks like a pretty normal alkalinity graph for 24hrs....

Essentially there is more time between doses to allow CO2 back into the equation.

 

[Randy Holmes-Farley]

The pH rise is identical dosing either calcium hydroxide or sodium hydroxide per unit of alk added.

One can certainly add sodium hydroxide at a rate identical to any method of calcium hydroxide dosing.

One can dose them identically, if that is a goal.

the ph looks like a normal PH graph too, the 45 min snapshot is a flat line of course, but it doesn't look any different from any other graphs not on the "Chris method"...im not seeing the life changing effect, that your talking about from those graphs, assuming everything is calibrated and true.
