Recently I bought a couple of Sötching oxydators from NewBreed Aquatics closing down sale, As I've been wanting one for awhile but didn't quite have to cash to fork out.
These sold for $15ea at like 40% off.
Shipping was really fast, and they arrived well packed in perfect order.
The box comes with:
1x glass bottle with plastic lid
1x ceramic holster
2x 82.5ml bottles food grade H202 (4.9%) oxydator solution.
fill glass bottle with H202 to within a few cm of the top.
Add catalyst. 1 for <30L, 2 for 30-60L.
Plug the cap back on carefully but tight, before inserting the bottle into the ceramic holster and placing in your aquarium.
Choose the appropriate concentration of H202 for your application, and add the correct number of catylysts, by doing this you can tailor the oxygen production in your aquarium, For example:
In my 40L tank I'm using straight 4.9% solution and 2 catalysts.
Where as in my 10L nano I'm using 2.45% and only 1 catalyst, (diluted equal parts with distilled water)
Store any spare catalysts somewhere safe so they don't get lost.
As advertised, the sotching oxydator produces oxygen aswell as an "activated oxygen" which apparently has a lot to do with neutrient and micro neutrient bioavailability in plants. They are also said to reduce algaes esp blue green algae and green spot.
Bubbling away peacefully in my tanks. :) they are lovely to watch when my Bazooka isn't running hehe.
So whether you want to increase oxygen levels in a planted tank without increasing surface agitation (which outgasses precious co2), Increase DO levels to improve shrimplet or fry survival rates, Run a quite tank without a filter for example on your bedside table where an aquarium or scape would add a sense of peace and nature without loud bubbling or humming of filters that can be annoying, Help battle algaes or even just improve general fish and shrimp health this product does it all reliably.
All in all, its clever German engineering combined with a sleek, sexy in tank look earns this product a full 5 stars from me.
