Re: Barnacle removal without scraping
One thing I should have mentioned earlier, make sure you use a good paint stirrer on the end of a drill, and give it heaps !!

Re: Barnacle removal without scraping
A bunch of amateurs dumping bird antibiotics into the marine ecosystem. What could go wrong?

I have to agree. A really bad idea. There is already a huge problem with antibiotic resistant bacteria that cause deadly diseases in people (like TB, and staph infections) and also antibiotic buildup in the environment. To contribute further to that problem in my opinion is highly irresponsible.

Re: Barnacle removal without scraping
Adding pharmaceuticals to anti fouling paint is as environmentally irresponsible and morally reprehensible as using tBt, IMHO.

Thanks, for the TBT mention.
I was fighting a moron, trying to buy TBT based Submarine Paint on CL recently.
Total ass and irresponsible guy, building his own vessel, didn't care at all.
Till the USDA, got involved.
It a regulated Pesticide in Washington State.
Too bad for him.

Re: Barnacle removal without scraping
I thought this was an interesting topic, as it effects us all at one time or another. What I wasn't prepared for was all the bullying and name calling. Is there really any need to call people "Idiots" or "Morons"?
Oddly enough, it's the prolific posters that are the worst culprits, picking on those with far fewer posts like they are God's gift to all things boating. As it happens, despite being strident and rude, some of the attacks are pure nonsense. All means of removing growth from anti-fouling will result in poisons being released back into the water and some jurisdictions, e.g. Vancouver insist all run off from hull cleaning must be contained and dealt with appropriately, no matter how the hull was cleaned.
So, does asking a question in this forum necessitate running the gauntlet of bombastic know-it-alls or is this meant to be a community were we share knowledge like a group of adults? I'm confident the accusations of "idiot" and "moron" would be greatly diminished if these were face-to-face conversations, so why don't we just act as though they are.

Re: Barnacle removal without scraping
There is a the paper on the net where a scientist used 10ml/l of ivermectin in antifoul paint with outstanding results. He warns that this research has not been approved and so does not encourage the use for environmental reasons. I recall farmers spending a fortune on chemicals to spray apples against black spot. Some smart aleck scientist discovered that milk did the same job. He was very quickly quietened.
It's hard to decide what is safe for the environment and what is good for business.

Re: Barnacle removal without scraping
Ive had the same experience with prickly replies on the forum but dont take it thar serious.
After all we dont have to read those replies do we. I just skim them over, take it ftom where it comes and move on to the next topic.
Must say I too am getting reluctant to post replies lately and you are right that it should be more of a pleasure.

Re: Barnacle removal without scraping
I installed a Ultrasonitec Quad system a couple of months ago.
The boat sat at the dock not used until yesterday.
We sailed to the San Juan's where we are now anchored.
The three year old Micron Extra bottom paint is absolutely clean.
