Redox potential

[Kingkong]

Hi bro's,

Following our Koi fanatics we are studying the redoxpotential. This value is about the power of reduction or oxidation in your tank. The more oxidation the better for your nitrificationcycle.

0-20 Rh is reduction
21-40 Rh is oxidation

(ORP/29.7) + (2xPH) + 6.23= Rh

This formula i found on internet.

ORP (oxidation reduction potential) can be measured by a digital meter. As you can see, a lower PH has significance influence on your Rh-level.

Any bro with more experience?

A friend of mine measured his tank water and had 26.

We are looking for the best value, no idea whats the best for our caridina cf cantonensis. If we have the value, how do we chase this higher value without touching the ph?

Anyone?

Very interesting topic actually.
I came across mentions of how a "coast to coast" super wide overflow surface would enhance redox potential and also when some people were talking about UV filters.

I'll be following this thread to see what can be learnt.

Interesting topic. Is this is able to reduce the amount of parameters that we need to monitor? At the moment, many shrimp keepers are already like lab scientists, with all their test kits.

[Navanod]

I doubt so Cheetf. It's another meter to buy and monitor!

[Kingkong]

Yes it is another value to monitor, we think it is an important one. Yeah lab scientist... A few months ago i knew nothing about ph, kh, gh no1 till 1001 lol

We think this redox potential is important because the power to oxidate is important.

A friend of mine started to inject ozon into his tanks to help achieve a higher Rh, he reached Rh 26 but injecting more ozon would not be very healthy to the shrimps.

Why we want to achieve this is due to the vids chris lukhaup has put on the net.
The natural habitat has tds of 60. The water is very clear and i have no idea what tje redox will be, but i can imagine a very high Rh.

Koi keepers and discus guys are more progressive with new techniques to improve their hobby.

Uv filters just kills the bacteria in your water, not really helping to get a higher redox value

Ah yes! It was ozone, not UV filter that talked about redox! I must've mixed them up

[Navanod]

Wait, now that I went back and read about it, UV is also linked to redox as ozone is sometimes created and the UV needs a certain redox potential to work.

[crescebi]

Is injecting ozon the only way to increase or reduce oxidation in the tank?

[Navanod]

Nope, normal oxygen and other oxidizing compounds can also be used

So shrimps are really more happy in oxygenated environment read a small article.thats why my tank has a sponge filter bubbling.

Injecting ozone? I believe ozone is used industrially to sterilize water and air. Where does your friend get it? Supposedly it is a toxic and unstable gas that must be produced on-site.

Actually, there are ozone sterilizers for aquarium use, alongside UV sterilizer filters.
Mostly used for marine tanks and very large display tanks though, as it is quite costly.

Very interesting topic brought up Kingkong, manage to read up abit about RP, where ozone is applied to raise oxygen level and breakdown organic waste, sterilizing the water therefore raise redox potential. Guess it is mainly used in marine aquarium along with skimmer and UV sterilizer.

Most ozonizer available for the aquarium hobby use a Corona Discharge method to create ozone. In a Corona Discharge unit, air is passed through a strong electrical field which causes atmospheric oxygen (O2) to break apart into single oxygen molecules. Some of these oxygen molecules will then combine back together after passing through the electrical field to form Ozone (O3). It is this free oxygen atom that attaches to dissolved organic compounds, which in turn causes them to break down into simpler forms that can consumed by heterotrophic bacteria , or recombine into forms that can be removed with mechanical filtration

Read the benifits of using it can help reduce nitrate, algae, pathogenic bacteria, circulating toxins and more.

Next level of investment? Guess have to spend more money buy ORP meter or redox meter to monitor also.

[Kingkong]

Zenith, you nailed it!!
Using ozon is to achieve a better nitrification proces.

My friend use a philips ozonisator / purifier for aquarium uses. The investment is ok, its like 50-70 EUR

The Rh meter is 70 Eur so yeah it will cost a bit.

Using spongfilter is ok, but pure oxigen in air is 20% or less.

I guesse my sponge filter should be sufficient because quite a lot of fellow shrimpers here don't even bubble their shrimp tanks I think. So now after reading this redox tread more people may want more oxygen content on their tanks and lastly thank you kingkong for bringing this topic out here really appreciate it.
