## Description

Product description Waterlife Octozin flagellated protozoacide.200 tablet (3 day course for 1500 litres)OCTOZIN is a treatment for internal parasites such as those which cause Sleeping Sickness, Hole - In - The - Head, Seawater Angelfish and Clownfish Disease, Malawi Bloat Disease and also early stages of Dropsy. OCTOZIN may also be used to treat Whitespot in seawater aquaria where CUPRAZIN cannot be used. OCTOZIN is harmless to invertebrates and algae when used as directed. You will require three separate days of treatment to complete the course.OCTOZIN is active for up to 3 days after the last day of use. Although internal parasites are destroyed instantly, external signs of improvement to the fish may take up to 7 days. Directions 1. Use three separate days for treatment. 2. Dissolve one tablet per 50 liters of water. 3. Repeat this process for three consecutive days.

Review: Octozin: a great medication to own especially if you keep Discus and / or marine fish - Octozin is a very effective medication especially for treating 'hole in the head' disease affecting Discus (freshwater) and other fish species and usually said to be caused by the flagellate protozoan parasite, Hexamita. Octozin is also effective against a wide range of other protozoan parasites such as Spironucleus, Cryptobia, Bodomonas, Trypanoplasma and Trypanosoma. In marine aquaria it can be used to treat the disease conditions known as 'Angel fish disease' and 'Clownfish disease'. It is also effective in marine aquaria against marine 'whitespot' where fish and marine invertebrates are being kept together and so copper-based medications cannot be used. However, for it to be really effective, the salt water in the aquarium has to be reduced gradually in concentration down to 1.017 in specific gravity ideally before the Octozin medication is added, and kept at this specific gravity for two to three weeks whilst the medication takes effect. Also, it does not say if the standard three day course of the Octozin is to be repeated at some stage during this two to three week period of low salt concentration. The specific gravity must be brought back up slowly by adding sea salt once the course of treatment is finished. Personally, I have found Octozin to be very effective at treating 'hole in the head' disease in Discus (freshwater).
Review: Really works - My parrot cichlid had white bumps on the head that turned into a concave crater. I was expecting the worst, but a couple of doses of this treatment cleared things up completely - 2 years later and my parrot is still going strong. Does turn water cloudy, but didn't appear to harm other fish. I did remove all snails from the tank prior to dosing (as per instructions), and didn't lose any other fish. Definitely saved my fish, so 5 star.

## Questions & Answers

**Q: I have a 4ft by 3ft by 2ft and the calculation works out 28 tablets does this sound right?**
A: Sounds about right to me I know I used a lot per dose. I think I used 18 on a 3ft x 15inch square tank.

**Q: Has this product cured anyone's fish of Dropsy?**
A: sadly not many seem to understand that Dropsy is a symptom not a disease. Dropsy is a symptom of Kidney failure and only antibiotics such as keneplex combined with salt (Epsom and aquarium salt) treatments have been scientifically proven to combat and reverse it. but it all depends on what is making the kidney fail. Internal infection, parstie, genetics, poor water? you have to find the root reason as treating dropsy you are only treating a symptom not the illness it's self.

**Q: Hi has anyone used this on Oscar hole in the head? How did it go? Did you have other fish in the tank during treatment?**
A: Hi don't know if this helps but my xl severum had bad hole in the head and this treatments works 3 day treatment but need to remove carbon from filters

**Q: Is this for all fish? does the packaging say it's not for any specific fish types? specifically cory dora and yoyo loach. thanks**
A: I’ve used it with sensitive fish, Discus mainly, never had a problem, even used at 3x recommended dose for a resistant strain of infection without issues.
The general rule is take care with scale-less fish such as loaches, but mine always were ok.

### ⭐⭐⭐⭐ Hope It Does The Trick
*by S***S on 18 November 2021*

I was surprised to see the tablets are the size of a paracetamol and for a tank of 40 gallons I dosed 8 tablets per day over three days. I believe the tablets are working for hole in the head on my uara chiclid . The uara is excreting a lot of mucus and the water is very misty due to the tablets. My discus are not affected with hole in the head and do not seem troubled by the medication.
