Twinstar..what is it?

[Ichthyologist]

OK, I'll bite and throw in my theory. It is an ultrasonic plate. The fine mist of bubbles you can see inthe YouTube videos is degassing of the water caused by cavitation. The efect is demonstrated in this video
Having worked with ultrasonic baths I would not put my hands in a tank with this device, if this is indeed the principle. If it is degassing the water it's not going to be good for flora or fauna.

Hi all,

Ah ha ... Lots of plants. | UK Aquatic Plant Society

I think the "Twinstar" is probably the source of bubbles in:

Hi Darrel - so are you going to tell him!🙂

Could be, the bubbles look localised and not the CO2 production of photosynthesis.

That is certainly another option.

I'm pretty sure the bubbles aren't evolved oxygen or CO2

I think he probably knows, and he doesn't say that this is pearling.

You can get the same micro-bubble effect using webbed urethane membrane, if you can get high enough gas pressure. They use these a lot in aquaculture/waste water treatment now (along with PTFE diffusers) as they offer advantages over EPDM or ceramic disc diffusers.

The unboxing video does not show any gas inputs, only and electrical connector.

To completely digress, I used to provide tech support for this membrane, made from Aluminium oxide.
Anopore Inorganic Membranes (Anodisc)

I know, I wasn't suggesting that as a mode of operation for the Twinstar, just another way of creating micro-bubbles. I still think it is an oxidator, although an ultrasonic plate is a possibility that I hadn't really considered, just like an ultrasonic mister in reverse.

Interesting, my suspicion would be that that is quite an expensive and specialist bit of kit.

Well that would be easy to test, it involves a match and me not being in the same room!

Hi everyone
I am growing rare plants for very long time.
And I didn't have this result only in one month and a half.

don't beat yourself up, your plants have always had amazing health with or without the gadget. creates a mysterious steam train effect though, which may catch on in its own right.

Yes, do the experiment, take it out and see what happens. I would bet that their is no difference.

Started seeing this in our local LFS too: ::: GC-Shop ::: Stunning Aquarium Simply For You. There's even a shrimp version.

It wont be long now ... every tank will have one 😉

 

[alanyusupov]

I think is good to have in the new tank for starting, before never started any new tank without algae, but this time I really don't have algae.
Problem was only when I went out to the sea side for 5 days, and I forgot to plug it on. When I came back I seen this.







Then I switch it on, did two times 70% water changes, then in a week, water in the tank becomes clean again.

I'm leaning towards ozone generator for the purposes of purification. Whether its solely responsible for algae control in a tank needs to be tested in an A-B test.

So I just read 6 pages of stuff and I still have no clue what this gizmo is or does. I fight my algae with my hands I dont care.

Had a quick chat with Dave Chow in Japan about this device. He is using it a while ago and now it's kind of there in his maintenance tool bag.

My question was that this only works with new tanks? Nope this works with any tank.
Which algae he seen is it good for? Cyano, Green dot, Diatom.
Putting in this device to an aquarium which has Cyano algae the algae dissappear fully within 2 weeks from the substrate too.
Plants grown quicker a little, but he correctly pointed out that this is not a cure for all. Helps with some things, but you need to take care for other things.

I see this as a helpful device for beginners mainly.

Waiting for my test product too probably will receive next week, then i will share my experience too.

Thanks Viktor I will really look forward to your personal test 🙂
