How can you have any issue with any other equipment?

The secondary of the transformer is not connected in any way to the supply, therefore there is no path for current to pass except from the too ends in the water

 

Can you also explain the difference between impedance and resistance if you are going to split hairs!

wooh… hang on a second.

Yes I can explain the difference between impedance and resistance as this are all parts of my job having to design control systems and why should you challenge me on that.

I also didn’t want this to turn into an electrical forum...

That post was not an aim to get you angry or to judge your electrical knowledge but to correct the common mistake people think with regards to 0V / earth.

But there is no earth point on the secondary side of a 12v transformer, therefore no possible reference that would affect anything other than something that gets between the two ends in the water.

By the way, I'm not angry, but you pulled me on what I said. I'm simply correcting it and letting you know that I know what is going on as far as the electrical side of things.

I didn’t want to turn this into an electrical forum.

So you are saying you never earth your secondary side of the transformer and leave it floating, as per my post I wasn’t not challenging your design. “I would imagine this application would be fine”

I didn't do anything to the transformer. It is a standard double insulated transformer with only 2 wires.

What is the VA of the transformer? I would imagine its small?

They don't give the VA of these 240v AC to 12v DC plugin adapters . They just give input/output voltages and output current. This one is rated at 1A

Gentlemen,

I am neither sparky or electrical systems designer as I build and maintain roads! I have just caught up with this thread and to add my bit........ I have followed Martins design and built one of these wands and from my point of view they work. I have lost neither fish or Coral as a result and have gained immense pleasure in watching Aiptasia melt and break up before my eyes. I have made shorter length wands for those harder to reach places, and now only occasionly have to use them. Try it and see I'm glad I did. Regards.

They always come back!

And I changed to stainless as they don't leech metals into the water.

Try the 20v one in a cup of water and find out!

These things still working? I have an original Majano Wand, but have not needed to use it in a few years. Seems simple enough to make.
