Chemiclean 20% Water Change - Why

[taricha]

This is a bit speculative, but I'll go with it.

Erythromycin itself - as far as I can tell just from reading a whole bunch - should not have a huge O2-consuming effect. Yet, chemi-clean almost always drops O2, and this is anticipated in the instructions.
It makes me wonder if this product is delivering erythromycin with a bunch of excipients/fillers like might be in pills (which would be broken down in a tank and lower O2) and there is room for a better version of the product without the excipients that could deliver just the antibiotic and have much lower O2 drop.

(I could be wrong erythromycin itself might dramatically lower O2 in some way that escaped my searching on the topic. )

I have been told by Boyd what is in chemiclean but have been asked not to share the formula so I will not. It is not a traditional antibiotic. The active ingredient is an oxidizer similar to Ozone, Peroxide, and Potassium Permanganate. Oxidizers like this have been used for years with some people continually using oxidizers like ozone. Yes this is a chemical but it is not like a traditional antibiotic at all. Technically all aquarium additives are "chemicals".

Like any oxidizer if you overdose it you will kill everything in the aquarium. However, oxidizers have been used for decades and are used by some of the most successful home and public aquarists. Chemiclean will drive you skimmer crazy after use and performing the water change will reduce the levels so your skimmer will more quickly return to normal. If you don't do the water change you might be forced to by dumping out the water in your skimmer cup for a couple of days.

@MarineandReef Jaron thanks for sharing this. Really.
I'm skeptical in the extreme of every aspect of that explanation.

 

[Charlie the Reefer]

I’ve pondered the same question, why remove 20% of the water? Seems arbitrary and useless no matter how you think about.

Exactly! I've made all the graphs myself to understand the effects daily/weekly/monthly 1%/5%/10%/20% etc water changes have on pollutants. Also obviously read RHF articles on it. Based on that, ONE 20% water change... it's just tough to wrap my head around conceptually!

BTW - thank you for reviving this thread everyone, I still am confused on the topic and any information helps. @MarineandReef Jaron thanks especially for that good information!

Did he mention the court case in Germany where it was shown to be erythromycin?

I agree with taricha. That explanation that they have been spouting for years is not even a very good fake.

That may well be the case.

All I know was I needed a legal engredient list for export that required the actual formula. On the legal document Boyd's provided there was no erythromycin listed.

And that was the nature of the case in Germany as well. No mention of a regulated antibiotic that the local government found in it: erythromycin.

Anyway, I cannot be sure what is in it, of course, just reporting what others have found, coupled with the implausibility of the claimed mechanism.

It would be interesting for someone to test the ORP of the product and in seawater it is added to.

All we need is one of this Milk Erythromycin Rapid Test Kit to solve this mystery :0)

I've used Ozone, peroxide for years and never experienced such an fast effect on cyano as chemiclean does. And don't think there is such an oxidizer that would kill only cyano but not other algae

I will not say what the ingredient is, but I will say that when I use Potassium Permaginate in Ponds It will remove green water and slime without bothering "Rooted Algae" on surfaces or damaging water plants. There is likely some protection the more complex algae have compared to the bacteria that make them more difficult for the oxidizer to kill.

 

[Randy Holmes-Farley]

FWIW, I tracked cyano and green algae (and many other things) when I initiated ozone for a series of articles. It had no impact on the patch of cyano I had.

 

[Randy Holmes-Farley]

I’m very curious for someone to measure the ORP effect of the Chemiclean. Maybe I’ll start another thread asking for folks to check.

 

[Randy Holmes-Farley]

Maybe someone will take some measurements:

Help needed with Chemiclean and ORP

The manufacturer claimed mechanism of Chemiclean is by oxidation of Cyanobacteria, rather than the suspected mechanism of an antibiotic. While it is not proof of the mechanism one way or the other, ORP measurements should at least indicate whether oxidation is plausible. I’d appreciate seeing...

[Randy Holmes-Farley]

Sure, I get the rationalization, but leaving 80% of the ChemiClean in the aquarium is not getting a substantial amount of material out, hence, the idea that the water change is a feel good activity.

I suspect that 20% was a marketing decision between doing something to remove the active agent and toxins released from dead cyano, and recommending a really useful level of water change that would turn off potential buyers with tanks bigger than a 20 gallon.

taricha took some measurements in the above thread, and the claim of an oxidizer in the product is not immediately supported.

Spot on! Thanks for going all in on this investigation! Looking fwd to the ORP study.

Best practices should be developed for unforseen problems. Just because you are not guaranteed to encounter an issue, doesn't mean a best practice shouldn't be developed for it. I.e., the "goal" is to have healthy, pest-free corals, that doesn't mean you shouldn't have a best practice for anti-bacterial/pest-removal dips.

But at the same time it doesn't mean going the route of chemical euphoria. As with many things in life the best practice is to understand how one got into the situation. Then we reflect and introduce change behaviors to prevent.

Wheel goes round and round...
