Can chemiclean affect dKH?

[JonasRoman]

My Alkatronic detected a slight increase in dKH around 24 hours after added chemiclean.

We do not know what chemiclean contains(or?), but due to its effect I would not exclude antibiotics. In that case maybe that can explain my KH rise if that for instance disturb the nitrification which produce H+...I just speculate, only saw this KH rise at same time as I added chemiclean.

Any comments or experience of this?

At least one of the ingredients is erythromycin.

Dead cyano would spill organic molecules of various sorts that can impact all of alkalinity directly, organism processes such as calcification and nitrification and denitrification, and may inhibit abiotic precipitation of calcium carbonate.

Extremely valuable info! In Sweden we discuss and we do not know. Some claim it is not antibiotic and if you read at their product spec you got an impression of that they promise no antibiotic.
I have always believed that it must be Ab as it works in almost every case and very fast.

Are you sure?! In that case they should change this text.

That was also What I thought

I saw some comments about erithromycin succinate being a specific form of erithromycin and that the label, while being technically correct, is misleading.

Found some references, see post 16 or post 3 from RC. Here's a post from Dr.@Randy Holmes-Farley.

Chemiclean is an antibiotic, erythromycin, despite misleading claims otherwise.

We always suspected it was erythromycin because of the very strange wording that it was not "erythromycin succinate:". Sort of like saying you don't have a red car when asked if you have a car.

But apparently a government office in Germany tested it and found it was erythromycin:

I have found that the ALk uptake in a system increases significantly once the treatment is complete and a water change and carbon added as recomended, I use a KHG guardian to monitor ALK.

The believe that the changes in the tank chemistry are dependent on the amount of cyano your getting rid of. If you have a significant amount you could see a significant change in your tanks chemistry. People that are getting rid of small amounts will see small changes.

I had a small amount of Cyano FWIW.

If it is erytromucinsuccinate or erytromycine”xxxx” or just erytromycin is of no importance here as that ”xxx” is only added to control Where it is absorbed in gastrointestinal tract etc. It is still erytromycin. I just mean that saying at the package that they do is very misleading. Most people of course interpret that text that it does not contain erythromycin at all, and that seems to be what they want. Not serious.

Well, nevertheless very good to get this confirmed as I have always suspected that it contains antibiotics.
With that knowledge I think it is very suspect advise they give that using this as a profylactic every month, and also I do not believe it is truth that it does not disturb some of the natural bacteria as well. Erythromycin is not selective at all.
