Hi there,

I'm thinking of purchasing a steriliser for my nano aquarium. I see so many examples of aquascapes with sterilisers in but can find so little real life comparison between using them or not.

- What has been your experience with an electrolysis steriliser?
- Did you see a boost in plant growth/health?
- Did you get one without having visible algae in the tank?
- Why doesn't it affect the development of BBA?
- Which product do people prefer?
- Do they work as oxygenators if there isn't much surface agitation?

Would love to hear your general thoughts! Thanks very much!

Thanks guys.

Yeah, I came by the thread before posting and noticed it was started 7 years ago! I was hoping there was a general consensus or, at least, an abridged version.

I've skimmed through the thread and get the idea of how it works, that it may have the beneficial affects as noted by Viktor (and claimed by Twinstar) but doesn't work magic and aquarium fundamentals still need following.

Is it safe to conclude, then, that it's beneficial for these specific algae issues and worth getting if (1) you have the disposable income and/or(2) like the look of it, otherwise it's unnecessary?

Have you tried them yourselves? It's interesting, there are not so many divisive subjects in the hobby.

I use it whenever I start up a tank (which is not often tbh). I use it untill the reactor is full of calcium deposits or whatever it is. By that time the tank is up and running fine so its use has run out. I believe it helps a tiny bit with preventing some spot algue and green algue, but not with bba for instance. And even if it doesnt help, the effect looks pretty cool and if you have visitors will almost always start a conversation when they see the white clouds going through the tank. I never regretted getting it :) But I've not done a side-to-side comparison so its just a gut feeling, and maybe that gut feeling is just my head wanting to make me feel like I didnt waste money on it. ;)

Hmm might aswell pitch in....

Firstly i have had both the chihiros and twinstar, and the twinstar lasts a lot longer than the chihiros. I've got very hard water, i assume most people on here have similar water parameters.

The chihiros disc worked for about 2 weeks until the output dropped and it got limescale on it, even after cleaning it wasn't the same. Where as the twinstar has lasted me 7months so far and i clean it every 3 weeks and it works great without a drop off in output.

Does it work against algae?
Highly doubt it, but i feel Like it may help keep things a little cleaner for the first month probably because of extra oxygen?

Does it look cool?
Definitely, i love it and so does everyone else. I would say the main benefit would be extra oxygen and everything that comes with that. Other than that i would say its pretty pointless, however it's something "cool" to spend your money on 🤣

I run the Twinstar on tanks at home.

loads of additional oxygen. Good for the filter and substrate at tank start up. I actually continually run them on the basis that if I have a good prune or reduce plant mass it’s still adding loads of oxygen that I’ve just lost.

the premise is that single cell things find it hard to live in an oxygen rich environment. It’s not a miracle cure for algae but tanks always seem easier at start up with one in.

Others have reported it has solved their issues with mould on shrimp carrying eggs and discus diseases but that is purely antidotal.

The Twinstar reactor plate has a coating of titanium and white gold. I’m unsure of the chihiros one I doubt it, hence the issue people have with running it in hard water.

And yes it does look cool, especially after a water change when the water struggles to dissolve the oxygen it produces! 😃

Jury out really, I’m a fan, others donot believe in it.


Hope that helps.👍

I am doubtful about its effects against algae. But there is one definite benefit: in my nano tank, I have it placed underneath my spray bar, so the device fills the whole tank with tiny bubbles and allows me to visually check the flow of water around the tank. I can actually see the water flowing forwards across the surface, then down the front glass, and then it goes backwards over my carpet plants. But if I let my stem plants grow too tall I can see this flow being disrupted or even blocked.

I've just ordered the twinstar unit. Hear reports of keeping the tank from algae, but only time will tell I guess. I must admit being a tech head they do look cool as well.. 🤓

I use the Twinstar unit on my tank. There have been three instances in the last 9 months where I have forgot to turn the unit back on after maintenance or accidentally cutting the power to it (it doesn't 'remember' its previous on setting) and I've seen a small but notable proliferation of BBA and staghorn within a week of the unit being accidentally off.

Purely anecdotal, and could be purely coincidental - but I do believe it helps inhibit algae, though more through increased levels of DO than anything the marketing might suggest. That said, I've seen similar small occurrences of algae when my filter maintenance has slipped or when my doser failed to dose macros properly - so I view the Twinstar simply as one of many 'tools' available to me that help me improve the environment in my aquarium, not in any way a magic bullet cure for algae.

I cant find any info on this, but perhaps someone here knows: If you have a tank thats larger then the maximum size the twinstar supports (200l I think the 'largest' model supports is), are you supposed to use 2 of them, or do you use one with reduced effectiveness (as far as they have effect)? As said, its effectiveness is subject to speculation, I feel it works for me, so would like to use it on my new larger tank as well, just looking at how currently. :)

Never mind, found the anwser on the twinstar UK facebook. Spotted a larger tank there using 2 twinstar nano+, so I'm assuming you can just stack.
