C328 auntie has for sale the Dymax Ozonizer at $58 , out of stock.
I will be considering the Coralife Ozonizer or the Hailea one. Do check out theCoralife one at http://www.esuweb.com/products.asp?E...lationship=100

I also realised there are those China made one with are used together with only Venturi skimmer , haven't seen one actually.
And sorry Monster to hijack yr thread here.

The price is about S$350 excluding shipping which is reasonable for a german product from a reputable online store in Europe.

Which LFS sells and how much is it?

Don think u can find it here in singapore Ken , the only brand u can find is Redsea and the review is very bad.

yap , sander unit is not seen in Spore mkt. I am only aware of Red Sea , Coralife...
btw , Monster , do check this ORP and PH controller from http://www.saltycritter.com/milwaukee.htm

cost USD179.95 (unit cost )

or this single ORP controller http://petsolutions.com/product.asp_...+Controller_E_

Thanks for the info bro.

Hi,

Overdosing of ozone will harm the livestock as the O3 start to attack the living tissues of the inhabitants.

Worst, leakage of ozone to our surrounding air is also harmful to human bodies.

Therefore, if one smells ozone in the air (house/room/in cabinet), switch off the ozoniser as it might be leaking or one overdose it.

Redox value should maintain no more than 400mg/L

I will not risk to go for China Made ones.

I will still go for Sander (Made in Germany) or AquaMedic (Made in Switzerland).

Cheers!

What is Ozone?

Ozone is a special form of oxygen. Normally, two atoms of oxygen form an oxygen-molecule. Contrary to this, an ozone molecule consists of three oxygen atoms.

Once this molecule is decomposed, new reaction partners are needed. All effects which ozone has on the biochemical course of reaction in the aquarium are based on its high oxidation power. Ozone is the strongest available oxidation agent. On the other hand ozone is environmentally friendly, as it only consists of three atoms of oxygen and it doesn't introduce any chemicals into the aquarium water.

Just as in nature ozone is formed in a flash inside the ozone electrode from the oxygen content of the air. Therefore, three oxygen molecules are needed to form two ozone molecules.

The Influence of Ozone on the Nitrogen Circuit

Ozone has an intensive influence on the nitrogen circuit. At pH-values of more than 7, this means that especially in salt water with a pH-value of approximately 8.2 the toxic ammonia is oxidized to nitrate (NO3). And at pH-values at around 7, like in fresh water, the toxic ammonia is not oxidized, so that bacterial oxidation is required. But in any case the very toxic nitrite step will be oxidized by ozone to nitrate - this reaction being pH-value independant - so nitrite is oxidized to nitrate in fresh water as well as in salt water.This is most important as nitrite even in small traces is a poisonous compound for fish and invertebrates. As shown in the following diagram, the decrease of nitrite and ammonia is the faster the higher the ozone content is.

Regarding the oxidation of nitrite with ozone, there should be considered that ozone can help purifying aquarium water. If there should be a sudden peak in the nitrite concentration, not only the ozonizer should be switched to maximum, but above all, the reason should be sought within the aquarium system. It might be an unnoticed perishing animal or uncontrolled decay is processing at the bottom of the aquarium. Often it is the filter which has not been cleaned for some time and which possibly works without oxygen, i.e. under unaerobic conditions. Especially mechanical filters with high filtering velocity only work under aerobic conditions at first. The more solids they accumulate, the more oxygen is reduced within the filter. The aerobic biology is slowly repressed and the filter tips over to unaerobic conditions which usually results in extremely high nitrite peaks as the filter does no longer reduce nitrite but on the contrary, might even produce nitrite itself. So a mechanical filter should be cleaned frequently or even better, a biological filter should be used.

The influence of ozone on organic substances

The general degree of pollution of water containing organic material can be measured - even if the individual chemical compounds are unknown - by the biological oxygen demand, the B.O.D. value. The lower this value is, the better is the water quality. As shown in the diagram below, the organic load (B.O.D.) can also be reduced by ozone. Especially organic turbidity which results in a yellow colour of the water can be reduced by ozone. Yellow substances put strain on fish! Ozone is able to make water crystal-clear.

The influence of ozone on germs

A very important characteristic of ozone is it's degerminating action. Ozone can, even in very low concentrations, kill viruses, bacteria and other germs. It has to be pointed out, however, that within aquaria or other fish systems it can not be the aim of the ozone treatment to sterilize the water totally. This would result in a negative effect on fish and invertebrates.

Ozonizers for aquaria are especially designed for the use in home aquarium systems. Overwhelming cultures of germs are killed while avoiding total sterility. Operating this way, fish and invertebrates live in healthy and biologically active water.

The Use of Ozone Improves Biological Filtration

Our experience proves that ozone treatment and biological filtration support each other very much. Huckstedt already wrote about this in 1960:

It should be discussed whether ozone treatment and biological activity of bacteria cooperate. The suspicion that by ozone treatment not only the harmful but also the useful bacteria (nitrification bacteria for instance) could be killed is quite obvious. But strange enough this is unfounded. Either these bacteria are not in the free water but mostly at the bottom of the aquarium or on the algae or they grow faster than they die. Probably both versions are correct. It can definitely be said that nitrification bacteria will die faster without ozone than with ozone.

What is the Adequate Dosage of Ozone?

This is a difficult question, as different circumstances in an aquarium result in different water conditions. Therefore, e.g. the fish/water relation, quality and quantity of feed, the filter system and several more criteria are very important.

As a rule of thumb the capacity of the ozonizer should be calculated by 3 to 5 mg per 10 gallons of water. This empirical value is the result of several years of experience. The dosage for intensive breeding stations or aquaculture systems is usually much higher. To avoid over-dosaging we recommend the use of a redox control meter.

Alvin, Sander is available locally and EE Lake Trading Co is the Sander agent. Their showroom cum office is located at 35 Kim Chuan Drive and person to contact is Stephen Lim at 62880852.

Just spoken to him and planning to visit their showroom today for a peek of the Sander Certizon Model 100.

Hi Ken,
What is the price?

02-03-2005, 07:53 PM

Recommended for my 6ft tank is the Certizon Model 100 which is retail for $420, before discount from dealers, and I am collecting the unit tomoro afternoon ...

However, Sander's agent does not carry the Redoxpotential meter and may have to source for another brand locally or purchase it from online store.
