Ex Machina 390 Posted February 5 Share Posted February 5 Anyone else seen this ? https://www.marinepests.nz/news/whats-your-level At this time of year our boat easily reaches level 2 in about 3 weeks . It would be more helpful if the councils mentioned the article would lobby the EPA to approve several new paints that have been languishing in their system . One application by Altex has probably passed the two year mark now . Quote Link to post Share on other sites
Psyche 794 Posted February 5 Share Posted February 5 They are painting themselves into an ideological corner, fouling is a natural process. It's what happens in the marine environment and is the basis of the ecosystem, us boaties provide free new blank canvasses for this process to occur- so what is the problem? I understand that moving one ecosystem to another and introducing new organisms is problematic but otherwise so what? Are they going to demand piers, jetties, navigation buoys etc be anti fouled- of course not! (Hang on we are dealing with ideologues so who knows knows!) Combine the removal of public cleaning facilities, the shrinking of hardstands (rates, land prices etc) the reduction in effectiveness of paints etc and a council that seems unsympathetic to the needs of average boaties to clean and maintain their vessels then we have a developing catch 22 problem 3 1 Quote Link to post Share on other sites
waikiore 477 Posted February 9 Share Posted February 9 Certainly as noticed this weekend Altex No 5 has been watered down lately , having been a very happy customer for 25 plus years I seem to have slime after two months not had that before..... Quote Link to post Share on other sites

And here I thought it was just my new mooring ... My previous #5 coat was a "bad batch" with so much copper in it that the blue paint was actually green, and only went blue beneath the waterline after a few months in the water. Best antifoul I've ever had! Maybe there's a case for adding extra copper ourselves to meet required performance 🤔 Quote Link to post Share on other sites
slanty 11 Posted February 10 Share Posted February 10 I've been using #5 for the last few years and have been happy but the above stories are a bit concerning. Any other recommendations for an easy to apply ablative? Quote Link to post Share on other sites

Are you sure? I doubt that Altex could change the formulation without re-registered it. Has there been a new product registration, or any change in the product information? There may have been, but I wouldn't rule out environmental changes as the cause. Quote Link to post Share on other sites

Yup I am sure, the local Altex Rep has been involved with the poor performance I have experienced and clearly blamed a recent formulation change. Was more a matter of a particular ingredient being removed or substituted with a lesser active product. Quote Link to post Share on other sites

This could get interesting, the product you thought you bought and yet the manufacturer changed a critical ingredient without really letting anyone know. hmmmmn. What could possibly go wrong? That has Law Suit City Arizona writ all over it. Pity Crew don't have a legal arm, taking on the shysters and bullshitters is really the last bastion. providing some level of of pushback otherwise the fuckers have won. I only say that witnessing the almost total capitulation of a democracy due to ignorance and apathy in the USA, please lets not allow that sh*t to happen here. 1 Quote Link to post Share on other sites

He did say it was in response to a now banned ingredient ... which itself was advertised by the marina as no longer permitted. Now here is a left field idea... I have worked on a barge that could be at sea for months then would enter a brackish water environment for a time. All the fouling would die and much would fall off. Would there be a case for a landlocked marina to have a pair of lochs that would allow the water in the marina to be maintained at a salinity level that would not sustain marine life?...

This comment caught my eye because the performance of Altex No 5 this year has been terrible, so bad I am currently out for a mid season reapplication. I antifouled in mid Oct and after 3+ months there are barnacles galore including a few Goose barnacles whats odd is that there is none of the usual slime. I hope this is a one off, I'm moored at Shelly park BTW. Quote Link to post Share on other sites

Very few things thrive in both sea water and fresh water. The only thing I can come to think of right now is the eel and they don't foul boat bottoms. /Martin Quote Link to post Share on other sites
Zozza 351 Posted February 10 Share Posted February 10 With the idiots running the asylum that keep banning antifoul ingredients that actually work, I am up for buying a 'moonshine' type anti-foul with all sorts of now banned ingredients, if anyone has the brains on how to make the stuff - I don't - I think I scored 20% in high school chemistry - but, I will gladly buy it and go tell anyone poking their nose in on what is painted on my boats bottom to go f**k themselves.

waikiore 477 Posted February 10 Share Posted February 10 Unfortunately the formulation has changed since my last application (3 years) its thinner not nearly as porridge as it used to be and goes on almost glossy -never before seen that, I too was v happy with the green that slowly went bluish in the past. Yes low salinity and various street run off polution does help (5 years in Milford creek between applications) Many years ago I witnessed people mixing up there own brews- the issue that struck me at the time was, and still is, many of their 'ingredients' were rather more toxic to humans than barnacles and they were splashing it about with gay abandon .The garlic was interesting but not convinced helped....

Psyche 794 Posted February 10 Share Posted February 10 I have heard that in certain regions where barnacles are a problem that cow drench containing ivermectin has been added to anti foul with great success 1 1 Quote Link to post Share on other sites

slanty 11 Posted February 10 Share Posted February 10 A bit of googling shows that the EPA have banned the use of Thiram in Altex ablative, effective from the end of 2023. https://www.epa.govt.nz/hazardous-substances/rules-notices-and-how-to-comply/specific-substance-guidance/antifouling-paints/ 2 1 Quote Link to post Share on other sites
