Dear family and friends quick check on results after approx 18 months . Final verdict will be in December this year.
So far vivid petite plus 20% of copper powder is the best vivid petite can get (the middle black sample vs original petite left sample)
The absolute winner is Altex 5 plus with 5% zinc (znpt) not zinc oxide, 10% copper sulphate and 10% paint any mould additive ( here in blue).


Modified Altex has no slime after 18 months sitting in the water. I am speechless .
My boat was Antifouled with the same formula 12/12/25.. not a single gram of slime. Boat next to mine went to Newcastle for antifouling in January and you can't see his watering it's covered in slime and barnacles..

For those who can't get zinc or other additives needed for their Altex 5 Plus, go to the nearest pharmacy and ask for 500 g of antifungal powder used to treat athlete's foot. Make sure it targets both Gram-positive and Gram-negative bacteria. Slowly mix the powder into your paint along with the anti-mould additive. Gram-negative bacteria are more dominant in our bay; however, Gram-positive bacteria are also present due to the mud. The powder is inexpensive and can help keep the hull slime-free for some time. This is a cheap alternative to zinc pyrithione.
Fair winds my friends and family!

Are you talking about miconazole?
