can this be used for tanks

[Rivermud]

First off just incase you did not know, ammonia is the main source of food for your biological bacteria that are present in a good running tank. So any trace amount of ammonia that the ge2 might gave off would be consumed by that. Which would not happen in the first place. My reference to a study was because I had a few tanks starting up at the same time. 3 with ge2 in them and 2 with out. All were treated the exact same. And all commonly testable parameters were tested daily (ammonia, nitrite, nitrate, ph, kh, dh) on all 5 tanks. And there was no difference in any of the parameters between tanks. And they all cycled with in a few days of each other. All that has been stated before. And I beleive that is a little more than just using it in a tank. Also please provide any proof that this ge2 has less adhession ability than the ge1. And i did state that the ge2 silicone that I used was the one with the toxins that the myth is about. And finally the only reason that I have labeled this a myth is because there is not one shred of valid proof that the ge2 has ever caused a problem in a tank. If there is not any proof to back up a statement then the statement is more than likely false.

To be fair, you stated nothing other than GE II.

I have geII black on 3 tanks. With all the mildew resistance and toxins and explosives and all the other BS that people says will kill your fish. They have been running for 3+ years with no problems. 1 of them has payara in it. They are more sensetive than discus and are doing fine. They other has a fahaka in it. And the last frsh barracuda's. All doing fine. Don't beleive the internet hype or myths that have no proof.

Nowhere do you mention Bioseal, your statement infers that GEII, not Type I is the culprit. Where the only true difference between type 2 and type one is the type of chemical cure compounds they use. It is the 'Ethyl Triacetoxysilane as acetic Acid that gives it its adhesion and strength, the GE type 2 (less odor) uses Methoxypolydimethylsiloxane and silicas. Type 2 GE silicon has excellent adhesion but not what aquariums need for long term exposure underwater. and nobody wants a seam leak a few months or a few years down the line.

"Polysiloxanes with 3-(alkyldimethylammonio)propyl pendant groups were synthesized by quaternization of n-octyldimethylamine or n-dodecyldimethylamine with linear polysiloxanes containing 3-chloropropyl groups and/or 3-bromopropyl groups attached to silicon atoms. The precursor polysiloxanes, poly[(3-chloropropyl)methylsiloxane] homopolymer and various copolymers containing (3-halogenopropyl)methylsiloxane and dimethylsiloxane units, were obtained by equilibrium cationic polymerization of linear and cyclic siloxanes with (3-halogenopropyl)methylsiloxane units. The polysiloxanes bearing quaternary ammonium salts (QAS) showed bactericidal activity against bacteria such as Escherichia coli and Aeromonas hydrophila when incorporated in a polysiloxane network. The activity was retained after 66 days of immersion in water. The QAS-containing polysiloxanes are also active in aqueous solution. © 2000 John Wiley & Sons, Inc.

Now it MAY be that bioseal is safe enough for aquarium use. However since there is no evidence to support it being aquarium safe, and there are no versions of silicon with the bioseal label that have been listed as aquarium safe, or even potable water safe for that matter, it would lead the logical mind to assume there are better options available. And, as I stated before, it is most likely right next to it on the shelf at your local hardware store. I would also state that in general silicones that DO NOT have an Anti Mildew or Anti Fungal Label are cheaper.

Holy crap I opened a can of worms.

RiverMud and a couple others have good points that fungicidal silicones are probably best avoided for the simple reason that they MIGHT be a problem, and there are a million other silicones you could use that WON'T be a problem. Hybridtheory - people are needling you because what you did wasn't a study, it was an experiment and thanks for sharing your experience, but a "study" would be much more involved and would probably be done by people with chemical engineering degrees and appropriate equipment to support their testing.

All I was saying is that nobody has proven that bioseal kills fish so saying that "Bioseal kills fish" is an unsubstantiated statement. Saying "Bioseal is probably bad for fish based on how it works" is perfectly reasonable though, and I wouldn't use it. There are many stronger/better/proven silicones on the market that work just fine.

personally i fall into the category better safe then sorry. I guess thats why i didnt eat crayons and glue in grade school, even tho the kid next to me was cramming them in his face.

i would only use silicon that list it is ok for use in aquariums

yea river mud has learned how to copy and paste. And has still not shown any proof what so ever. to the OP good luck on your quest and may you be bright enough to lead instead of follow common internet myth's.

Thanks for all your input. But sorry im not that bright and im going to with the general public. Better safe than sorry

While a your idea may have "some" merit there simply isn't enough of a benefit to warrant the risk, nor do we know want to generalize all of the "bio whatevers" together since there are different formulations in each brand and model within the brands. Typically you will receive poor responses around here when you come off like an ass, which clearly you have done. Unless you have technical proof to back up your statements, I wouldn't start demanding that someone shows you tech proof to prove it wrong... If you want people to listen to you then you need to prove your point and not ask that they prove you wrong.

 

[hybridtheoryd16]

you can not get any better proof than to show a very sensetive fish living in a tank with your so called deadly silicone. And all I ever asked for was some proof that the stuff hurt fish. If your going to get butt hurt because you can not prove something that you beleive in so strongly. Then i have no idea what to tell you. i am feeding my proof everyday. I guess some people can think for them selves and some can not. this thread is way off topic so I am done. I can provide visual proof any given day to back up my claim. unless someone can provide ANY single peice of proof to say other wise i have nothing to say.

 

[basslover34]

again your failing to see the point that not all products are not created the same.


The more you respond without actually reading the posts which your responding to the more of a fool you look like. Your having arguments with yourself at this point since the people that you're trying to fight with have agreed that there are some products which very well might be safe...however not all are going to be of the same quality.

 

[matt.beyer]

only use 100% silicone!

 

[Columbian Shark Catfish]

test it? :S

how about this stuff
