Ja sam nasao na jednom klipu da radi samo po minut u razmacima po 2 sata. Ne oslobadja CO2 nego neke druge gasove. a ako se radi sa obicnom metalnom resetkom onda ona mnogo brzo rdja, i rdju oslobadja u vodi, a kolko znam rdja je otrovna. A od inoksa neznam zasto ne valja, mozda bi blue mogo da kaze...
Vrsi elektrolizu vode
2 H2O → O2 + 4 H+ + 4 e– (Anoda)
2 H2O + 2 e– → H2 + 2 OH– (Katoda)
2 H2O → 2 H2 + O2
S tim sto sto je za nas interesantan OH-, koji se nalazi i u hidrogenu. To je neka moja logika, mozda nisam u pravu. I mene interesuje zasto INOX nije dobar izbor za elektrode

Inox je verovatno najbolje diy resenje, medjutim od ozona (ako ovo uopste proizvodi ozon O3) svim metalima je ubrzano rdjanje, a sa ugljenikom gradi (ozon) i neka jedinjenja koja mozda budu i dobrano stetna za akvarijum
Ja cu da probam da napravim, samo neznam koju voltazu i aperazu da koristi, vidim neki koriste i po 20V.
Користећи електроде од платине, водоников гас би се видео да испарава код катоде, а кисеоник код аноде. Ако би се користили други метали кисеоник би реаговао са анодом уместо да се ослободи. На пример користећи електроде од гвожђа у раствору натријум хлорида, гвожђе оксид ће се наградити код аноде који ће да реагује и створиће се гвожђе хидроксид. Када се створе велике количине водоника електролитичка ћелија се загађује и због тога се гвожђе не користи у комерцијалној електролизи.

Evo jos jednog teksta:
Već sam spomenuo da se za elektrode koristi nehrđajući čelik. Moguće je koristiti SS 304, ali se preporučuje korištenje SS 316L, jer daje najbolje rezultate.
Elektrode od INOXA se ne mogu koristiti jer pri elektrolizi oslobadjaju heksavalentni hrom koji je veoma otrovan...
Najnovija generacija HHO generatora izrađuje se od plemenitih metala kao što su titan i nikal. Zbog velikog električnog otpora, anoda titana mora se obložiti mješavinom metalnih oksida plemenitih metala kao što su iridij i rodenij. Sve to značajno poskupljuje uređaj, ali zato daje puno kvalitetniji hho plin i praktično nepoderivi generator.
Sto nam daje ideju da mozemo koristiti elektrode iz tog HHO uredjaja koji se koristi kod automobila, naravno ako neko nadje, a kolko tu vidim mozemo da napravimo rasetkicu od Nikla, toga bar imamo, od branika za bajseve samo je perforiramo.
A eto i zasto je skup taj uredjaj, najskuplje su elektrode na njemu...

Hi
I have contact them about Twinstar
and got this answer.
Basically, there are a lot of environments of aquarium that are varied depending on the users and also there are many reasons why Green algae occurs.
Before going into the details, it is necessary to understand why the Green algae occur in the aquarium. Green algae are excessive carbon dioxide (CO2) that artificially supply fertilizer ingredient including surplus nitrogen, phosphorus from soil and light. This serves as a supplier who makes the environment for algae to occur. Consumer will be water plant and green algae.
If water plant absorbs provided nourishment 100%, it will be the most idealistic environment where the Green algae don’t occur.
If you look at the initial environment after setting aquarium, water plants a bit slowly take root in the ground after planting rather than growing actively and then absorb the nutrient. However, initially nitrogen and phosphorus in soil are the most and they will be released excessively into the water.
Although there are a lot of nutrients, the amount of waterweed’s nutrient absorption are not enough. For that reason, Green algae occur. (If you provide strong lights and enough CO2 from the beginning, Heir green algae may appear before and after 15 days. Heir green algae occur when nutrients are abundant.) At this point, experienced aquarists normally increase water changing amount to keep the balance, or reduce lights, or try to prevent Green algae by putting Yamato shrimp, dozens of fish which eat Green algae.
Even if new water plants seem clean with your bare eyes, you can’t see the minute green algae attached on water plants. Therefore, we recommend putting some Yamato shrimp to prevent their growing. With only ‘TWINSTAR’, you cannot remove the green algae.
With enough light and nutrient, and CO2, water plants can take roots in 45 days and fully grow (demand increase period). Along with the growth of water plant, nitrogen and phosphorus from soil will be run low. If you plant a number of Stem plant, aquarium environment will start to change from 60 to 90 days. The biggest change is a lack of nitrogen and phosphorus. When nitrogen and phosphorus run short, Green algae will grow on a glass wall of aquarium. In case of a lack of light, Brown algae might grow usually.
As mentioned above, environments of aquarium continue to change, and coping methods should be varied with them.
Lastly, depending on the kind of water plants nutrients, speed and amount of nutrient uptake rate are different. Hemianthus callitrichoides “Cuba” grow slowly and nutrient absorption is very low. However, Glossostigma elatinoioles absorb a lot of nutrients and grow quickly. If you plant both two water plants in the same condition, Green algae will grow more in Cuba planted aquarium.
Like IWAGUMY, if a lot of CUBA is planted with lots of stones layout, it will become Hard water with water pH. Consumer cannot do its role, so green algae will be likely to grow more and more.
In conclusion, the effect of TWINSTAR depends on which water plants you plant and how to manage them. In case of 90cmX45cmX45cm size water tank, we recommend putting 3 Yamato Shrimp and 3 fish which eat green algae because they will act as the buffer in various conditions to maintain a constant effect.
Judging from that you didn’t mention about the effect of Heir green algae, we think that you didn’t test Twinstar with new setting. Also you didn’t mention Growth of plant, so please try to set again and check.
For your reference, you cannot expect the effect of Growth of plant from the aquarium over 30days. It is related to Law of minimum or Liebig’s law.
TWINSTAR mini has 1 operating mode, it is designed 90~120L size fish tank to prevent green algae from occurring in waterplant. TWINSTAR NANO model has 2 operating modes, Mode 1 is for 90~120L size, Mode2 is for 180~240L size. Super S is designed to keep aquarium fish from disease and it can prevent any diseases of fish in 300L~400L size aquarium. Mini S is the purpose of disease prevention in 120L aquarium.
Plus we attached bloggers’ review from their blog so please refer to it.
Effect on kind of algae
- Hair/Thread algae : 95%
- Brown Algae : 90%
- Blue green : 80%
- Fuzz algae : 80%
- Green Dust algae :80%
- Green spot : 85%
No effect
- Black brush / Beard

Posto vidim da neki pricaju da mrezice od inoxa nisu dobre,a tesko da cu naci od titanijuma, nikla ili platine, da li si prmetio neke negativne efekte po ribe i ostali zivi svet. Da li si primetio pozitivne efekte po bilje? Koliko puta i koliko vremenski u toku dana ti je aktivan twinstar, i na kom naponu radi? Ima dosta informacija na netu o tome, ali eto podeli sa nama kakva su tvoja iskustva.
