So mark does it do anything usefull now that time has past?

Mehr Arian - 5 years ago

hello Mark , This makes solution electrolysis fairly dangerous, because water is composed of hydrogen and oxygen. ... The water itself becomes flammable !

Lori B - 5 years ago

Is this the same as an ozonizer? From what I've read they break apart water molecules and the oxygen atoms recombine into O3. Is there any potential for overdosing a tank with ozone?

Johnny White - 5 years ago

I dont understand why the water doesnt short circut the two screens. Putting two electrical connections in water should just short everything. Could you explain why this isnt shorted by water? To afraid to try this without knowing it wont electrocute me.

Pure water is a fairly poor conductor. tap water contains trace amounts of compounds which make it able to conduct electricity to some degree but offer some resistance to the flow of electricity. What is crucial is the compounds that are in the water. seawater for example is much more conductive than freshwater. because of the dissolved salt (NaCl) . in seawater - you'll get some hydrogen chloride being formed at the cathode rather than just hydrogen. Also - what you are using for the anode and cathode is important. 316 grade stainless steel will not corrode as easily as many other conductors. Platinum coated mesh is even better but more expensive.

The phone charger is a transformer and only 12 volts so no chance of that.

Johnny White - 5 years ago

Very cool! Really enjoy your videos! Thank you for doing them.

What volt adapter are used here???

MARK'S AQUATICS - 6 years ago

12 volts

Hello i made the same but the colour of water change to orange and I don't know why please if you have the answer let me know

j rich - 6 years ago

You oxidized steel or iron which is called Rust

MARK'S AQUATICS - 6 years ago

Hi. You probably used galvanized metal. You need to use stainless steel mesh ok.

abraham99929 - 6 years ago

Have you tried to put a match to the surface?

j rich - 6 years ago

It will flare

Mark,
Question? I built one of these and submerged it to test it outside my tank in a bucket. It almost immediately started turning the water orange. Left plugged in for a couple hours I had a dark brownish greenish sludge floating on the top. Any idea what is going on?

MARK'S AQUATICS - 6 years ago

Ah! You must have used normal metal mesh. You need to use stainless steel mesh. When you use normal mesh and run the current through it will break down the mesh to rust .

Hi mark Did you use this in your tanks? Iv been looking into them afair bit now seen a couple of diy videos on them now just wondered if they did work as claimed? Whats your opinion on These are they worth making? And did the phone Charger hold up 6v bats aint the easiest to come by nowadays are they! But got everything out poundland to do the job love your diy videos keep them coming!

MARK'S AQUATICS - 6 years ago

Damn4got cool. Just remember to use stainless steel mesh ok.

Damn4got - 6 years ago

i found a 6v charger for a baby monitor on amazon mate. Gonna make mine out of a weed grinder as i can't think of anything else that snaps together and is small, also mine will be on a plug timer. thanks mark :)

MARK'S AQUATICS - 6 years ago

To be honest I built it for a project, it worked just like a twinstar but not so sure on the results .

Chris Locke - 6 years ago

btw, to me knowledge, its not sterilzing anything... its creating ozone, adding oxygen to the water... nothing more, again, not worth the risk.

chefdan87 - 5 years ago

Whats the risk?

j rich - 6 years ago

Chris Locke it’s not adding anything

It’s electrolysis which breaks water H2O into its base components H (hydrogen) and O (oxygen)

Oxygen does have a cleaning effect which is why Hydrogen Peroxide is used on cuts and abrasions

Chris Locke - 6 years ago

yikes, man... unonown paint, unknown plastics, unknown metals, glues, AND electricity all in your tank?? definitely not worth all those risks, buddy... in my opinion only.

Robyn Enns - 6 years ago

If put hand into water and its turn it on,will make shock electrical?

Dessert Qq - 6 years ago

Okey..thank you.
Have nice day.^^

MARK'S AQUATICS - 6 years ago

No. It's only twelve volts.

dentednj - 6 years ago

OMG I was wondering what these were: https://www.akvaryum.com/Forum/twinstar_nano_k772280.asp ! They want over $65 US for them and $25 for just the head. I didn't realize they were sterilizers!

MARK'S AQUATICS - 6 years ago

Very expensive and so easy to make.

Catalin T Adrian - 6 years ago

Hi, thank you very much for sharing your idea, I make one and now the question came.....
I tested in an vase and water became brown-ish sort of, maybe the grill I use is not good?
How will affect the shrimps?
My tds is 180, it vill do the job this twinstar?
Can I use an 5v/500amp phone charger?
Many thanks for your help!!!

MARK'S AQUATICS - 6 years ago

Hi. The mesh has to be stainless steel or it will break down and turn water brown.

MARK'S AQUATICS perfect! Wasn’t sure if they touched the plates that it would shock them somehow. Thanks for letting me know :)

Reg Pollock - 6 years ago

Question. Will that not take the Hydrogen & Oxygen out of the water?

MoreChannelNoise - 6 years ago

@Gary Read One of the benefits of living in Holland, they use uv not clorine!

Gary Read - 6 years ago

Bradley Fortner o3, ozone, it breaks the electron bond, leaving a two single atoms with a spare electron, making them bond with the first o2. They meet making. Mainly highly reactive o3, but some small amount of o1, that is dangerous to organic life, as it is what we call a free radical. Both the very small amount of free radicals and the unstable o3 will react with anything with a free electron space. In some European countries they use a combination of ozone and uv to clean and sterilise there tap water, leaving no trace.
Saddly we haven't catched them up, and because of cost of initial outlay, would rather pay more to poison our water with chlorine, and industrial waste from the aluminium and nuclear industry in a form of hydrofluoric acid, they pass off as fluoride, that would cost them billions to dispose of.
Sorry to go off topic, really pisses me of that we do this, instead of using ozone

Reg Pollock - 6 years ago

Yes, I had a brain loss. Sorry

Bradley Fortner - 6 years ago

It's actually just destroying the water by reducing it to it's basic elements. The oxygen and hydrogen simply escape through the surface. The bubbles popping at the surface will oxygenate your tank water, just like your pump/filter already does. But, as far as sterilization goes, I have no idea how water being destroyed sterilizes the water that hasn't been destroyed yet. If it even does. I think these things are just gimmicks personally.

Kennan Ho - 6 years ago

So essentially, it's creating MORE oxygen, and not stripping oxygen out?

Reg Pollock - 6 years ago

Yes Thank you.

ISCREAM92 - 6 years ago

Water = H2O. The sterilizer breaks down the molecule (electrolysis) to H2 (hydrogen gas reduction at the cathode) and O2 (oxygen thru oxidation at the anode). This means it actually consumes the WATER itself (in VERY VERY tiny amounts), so in principle only your water line should diminish.

Reg Pollock - 6 years ago

Thank you for your quick and honest response.

MARK'S AQUATICS - 6 years ago

I'm going to be honest I haven't go a clue how it works. Just thought i'd build one. I don't think the makers of it do either.:)

gary davies - 6 years ago

Good stuff Mark , I wonder if one of these between the 12v supply and the reactor would work to say let you set for 10 seconds every hour ?
Love watching your video's .

Neeraj Batra - 6 years ago

Whats been your experience Mark with these sterilisers, could you see any perceptible difference in the health of fauna or water clarity?

Gary Read - 6 years ago

MARK'S AQUATICS was you getting a sooty build up in the water?
I thought of doing it to, but because I didn't know what alloy they used, that wouldn't put a high metal content in the water and soot. It used to only take 20 minutes using silver bars, to make distilled water carry enough nano particles to work as an anti microbial. Never used antibiotics since. But there was a lot of soot, and I wonder if this stainless steel will cause any problems.

MARK'S AQUATICS - 6 years ago

To be honest I couldn't say. I built mine, tried it for two weeks and didn't see much difference.

hi mark can you please help me how to use and how many times should i use this aquarium sterilizer? thanks

Mad scientist at work, don't try this at home children :)
Love your DIY videos!

BBB - 7 years ago

It occurs to me Mark that one of those seive meshes (assuming they are made of stainless steel) could be covered in moss and suitably holed to make a lovely big dome for shrimp to hide in. I think they can be bought in smaller sizes too. If unsuitable for shrimps they could be used in a community tank for the catfish.

Stoned Savage! - 7 years ago

Anita Williams i used a Twinstar steriliser with a stocked tank so im sure it will be fine :)

MARK'S AQUATICS - 7 years ago

Hi. the phone charger is only six volts so no chance of a shock. Its the same voltage as a six volt battery for a torch, the safest way is to use the battery if your not sure about chargers. It adds oxygen and hydrogen to the water this has a sterilising effect killing algea spores and pathogens .

KoiPondPeppy - 7 years ago

I can get past electricity in water. How does that not shock you? Very interesting. Does it add oxygen to the water or just sterilize it? You're so full of ideas!

Monkey Nut - 7 years ago

I would be too afraid to electrocute myself LOL

Aquatic Haus - 7 years ago

I still doubt if it really works even tho I bought one for my planted tank lol
