Anyone dont change water and dont top up water?

uncomfortable lah....

must give my fish fresh water... like fresh air to me

hehehe

I also believe in changing water for you can never replace some lost minerals and elements and you can never able to remove the waste without getting them out in the first place. basically, we are just diluting our tanks water and maintaining them at a reasonable level where the filtration can handle and the fish is healthy imho.

i totally agreed with Bro Koji,to me just keep it as simple as possible. In today fish keeping hobbies there are alot of sofiscated equipment and device that claimed it will keep water at tip top condition,but so far has any of this fish winning any competition becoz of the equipment? so far all the fishowners who won competition which the tips they gave are simple,just do WC or aged ur water b4 WC. therefore your water will alw at tip top condition. Keeping fish is the same like any other hobbies,they r rule and regulations u need to obey. Doing WC is a must, if u r too lazy to do that then this is not a hobbie for u. Using those equipment just to slip certain steps in fish keeping is not an alternative but an excuse.

I posted this previously. This is lab data when my american partner was testing the equipment in water districts in the US many many years ago. If you look at the nitrate portion, there was a 41% reduction in just 3 minutes treatment of the equipment. The longer the exposure the lower it gets. We have modified the system to aquarium. Not as stong but still very effective. I am also putting again the summarized data table we compiled (2nd pic). The system cleans water very well... and increases the water's dissolved oxygen.

What concerns me is that the systems in which this device were trialled by Electropure did not pump a small aquarium of water round and round indefinitely.

Instead they took batches of sewage water, processed it then released it and took in another batch. This may seem like an insignificant difference but if some factor was released into the water as part of the process then the concentration of said factor would continue to increase indefinitely in a closed system. This is the same problem which occurs using ion exchange resins on a continuously re-circulating system. The solution to both systems is that you need to perform water changes.

I have trawled the web for information on trials of the Electropure system and can confirm that there are indeed a number of successful trials using their system to treat sewerage. However, I do still have one concern about the fact, stated in all of these trials that a sacrificial aluminum (aluminium) electrode is used. The claimed rate of usage of this electrode was 0.50 AU$ of aluminium for every 1000 litres flowing through the reactor.
(for example/ http://www.electropure.com.au/pdf/techpaper5.pdf )

In view of the toxicity of aluminum I would be rather concerned of the use of any system which continually released aluminum into a closed system. Can you confirm if there are any sacrificial elements involved in your system Oxyman ?

although i dont fully understand, and the test does not look well planned...i will prefer to change water once or twice every week

give my fish some fresh water should be good

--------
My partner discovered the technology some 20 years ago. Then technology development years after that. That's where he tested with water districts. Then went to several countries for wastewater treatment projects. Now he's semi-retired. I have present data but still with wastewater treatment in fastfood reasturants.

Electropure in the website you referenced is not the same. Aluminum is not used as an electrode in our system. And furthermore, the plates of our system do not wear out or corrode like what you normally experience in electrolysis.

I will show you docs with actual reference to specific matters on the reactor tomorrow. I will just get the reference and clear it with my partner.

IMHO, changing water/topping up water is necessary in fish keeping. The only question is the frequency and methods. I've some questions here to ask,

1. Why need to change water?
2. Why some hobbyist prefer to change water everyday?
3. Why some hobbyist prefer not to change water too often?
4. Why some hobbyist prefer no wc but just by topping up?

Is there a only ONE correct method in keeping Aro to it best?
Learned that our gland champion's master Ken yg changes water everyday. Is this the only way for our Aro to be in top condition?

I am a old lazy person and i keep my Aros in few lazy methods. Hehehe, althought all are eating well but my red can't turn more red and my XB turn more gold.

Do you have anything to comment?

Regards

bro TOM32, i have intention to meet up with you to share some ideas. wonder if you have time. I have an important day tomorrow which will decide things to come, can I do a raincheck for next week.
cheers

My partner says that if he gives the information on the plates material and all, it will be giving out his proprietary secret.

I guess the only way to do it for you guys is to work out something with the people who want to try it out... even with 1 unit. If some of you would like to try it, lets work out the details.

Bro tagore

13 - 16 Dec will be outstation. I will pm you for more details.

Here is actual lab dta when my partner was doing his testing with Sewege districts in the United States many many years ago...

Interesting, still I got some reservation on application at this moment. May work around it for less water changes eventually
The purification process resulted in increase in chlorine level, also as shown in the analysis report. This is not really desirable for aquarium purposes. How u go about managing increase in chlorine residue in aquarium?
Think the link here provide a better understaning of the chlorine gas production : http://www.cediuniversity.com/Index-3e.html

[chariot35]

I think the correct name to this process is Electrolytic precipitator/separator . I might be wrong though. There is no sacrificial anodes here. I 've done several projects similiar to what Bro Oxy is referring. One happens to be our very own ENV's incinerator plant. Think i still got some enginneering reference/design kept somewhere. But I still prefer to keep it simple and water change. Think we should learn to enjoy water change instead. I haven't actually succeeded yet. haha.

Cheers everybody.
