Dixon1990 Posted June 3, 2007 Report Share Posted June 3, 2007 i use selleys GLASS silicone sealant CLEAR. You just need to read the back of different tubes and look for one that says safe for aquariums or something like that. Quote Link to comment Share on other sites More sharing options...
sub.z Posted June 3, 2007 Author Report Share Posted June 3, 2007 i checked a few and they all said not for aquarium use but cheers ill go get some of that tomorrow That would be ok for glueing rock together wont it? Were do you get that sealer from? Quote Link to comment Share on other sites More sharing options...
Pegasus Posted June 3, 2007 Report Share Posted June 3, 2007 I went into Mitre 10 and they said that none were for tanks Hard to believe that they don't stock a suitable sealant. The type you want is as above... or one by Rosfoc.. called RTV Silicone Sealant .... Professional for Glass and Ceramic use. That would be ok for glueing rock together wont it? I wouldn't trust ANYTHING... unless it said it was safe for aquarium use. ANY decent hardware shop stocks it. Quote Link to comment Share on other sites More sharing options...
sub.z Posted June 3, 2007 Author Report Share Posted June 3, 2007 I know i dont even think she knew i just think she was too lazy I gave her a piece of my mind Ill go have a look for the one above Quote Link to comment Share on other sites More sharing options...
Barrie Posted June 3, 2007 Report Share Posted June 3, 2007 I am a glass merchant Through the glass merchant supplies, there is not ONE silicone that is made food safe and that is what you are talking about. The tests needed to garentee food safe product cost thousands of dollars and the market is far too small to bother spending that amount of money on. In saying that, silicone is not an adhesive (glue) but we use it for that as well without any problems I use Dow Coring 580 clear and Dow Coring 480 black for my tanks and have had no problems. The person behind the counter of the department stores has no "indepth" knowledge but has an overview on most things but still relies on packageing and suppliers back up for more indepth information If glueing rocks together I would tend to read the lable and see what is OK from tiles and the like, glue them together then soak them for a few days changeing the waters a couple of times of if possible put in a fish to make sure that no leaching has occured Quote Link to comment Share on other sites More sharing options...
sub.z Posted June 3, 2007 Author Report Share Posted June 3, 2007 So it wont be toxic for the fish if i try that method? Where do you get that stuff from? Quote Link to comment Share on other sites More sharing options...
Barrie Posted June 3, 2007 Report Share Posted June 3, 2007 there can be no garentees but an educated guess would be that you will be OK Most err on the side of caution. the 480 black use to be used on mussel tanks (for live mussel eating stores) but as there is no testing done, I cant garentee it and there fore the sea food shops tanks cant be repaired. I use that glue on 12 tanks If just sep up and feel very confident that all will be fine. Simple thing is that untill tested, no-one can say yes for sure Quote Link to comment Share on other sites More sharing options...
sub.z Posted June 3, 2007 Author Report Share Posted June 3, 2007 ok, is '480 black' the name? Ill go hunt it down this morning i think if i rinse it thoroughly and and not put it in my tank for a few weeks i should be ok Quote Link to comment Share on other sites More sharing options...
Barrie Posted June 3, 2007 Report Share Posted June 3, 2007 your local glass merchant should stock it but if they done, have a look at "Glass Corps "site www.glasscorp.co.nz they import it Its a matter of reading the back label and makeing sure that it will do what you want it to do then allowing enough time to cure 100%, normally 1 day per 1mm thickness of joint. ie; 6mm joint will take around 6 days to cure fully under temps of +20cel hope this helps a bit Quote Link to comment Share on other sites More sharing options...

Bluetom Posted June 3, 2007 Report Share Posted June 3, 2007 I have always been of the understanding the most important thing for aquariums is that it does not contain mould killer, as some coloured silicones and grouts do to prevent discolouration. Acid cure I believe is the thing to look for. Rinsing silicone is unlikely to do much as if anything is to be leach it will continue until the silcone is degraded. I've always used fosroc RTV, it claims on the back to be ok for aquarium use and is only $14 for a caulking gun tube, have used it alot on my tanks never had a problem.

Barrie Posted June 3, 2007 Report Share Posted June 3, 2007 no the name is Dow Corning 480 (black is the colour) and Dow Coring 580 (Clear is the colour) There will be others that use other brands but thats just what I use. I like the black in colour as I think it looks neat in apparence whereas the clear can look a bit messy Quote Link to comment Share on other sites More sharing options...
stompa Posted June 3, 2007 Report Share Posted June 3, 2007 sub.z just go to mitre10 and get sellys all clear and use that its fine. i did the same thing 3 odd years ago and its been under water the whole time and its still fine...... or contact inside oceans on here and he sells silicone for about $15 on trademe which will do the job fine........

Faran Posted June 4, 2007 Report Share Posted June 4, 2007 I have worked with a professional tank maker and made quite a few tanks myself. The silicone we use is Silaflex RTV and it even says on the label that it's safe for aquarium use. Same as mentioned above by Pegasus.

Barrie Posted June 4, 2007 Report Share Posted June 4, 2007 never realised that RTV was still arround was the leader when we first started useing silicones, Ive probably made a couple of thousand tanks useing it and glazed the glass into Vindex launches useing RTV Quote Link to comment Share on other sites More sharing options...
jolliolli Posted June 6, 2007 Report Share Posted June 6, 2007 Animates also sells stuff that is suitable for aquariums.. most likley a bit more expensive than going to mitre 10.. i was unsure about glass silicon so splashed out the extra $5 on the tube at animates and its worked a treat Quote Link to comment Share on other sites More sharing options...
sub.z Posted June 6, 2007 Author Report Share Posted June 6, 2007 Cool I see inside oceans is selling some on trademe for $12.95 Prob go with that :bounce: Quote Link to comment Share on other sites More sharing options...
Pegasus Posted June 6, 2007 Report Share Posted June 6, 2007 Amazing that you ask... Im making a rock feature for my tank and want to know what i use to glue them together and is ok for tanks I went into Mitre 10 and they said that none were for tanks Im confused, do i no use silicone? Then you say: I see inside oceans is selling some on trademe for $12.95 Prob go with that . . and you get all these answers from members that have made tanks .. some of them for decades... and told you the right stuff.. and where to get it.. but then you go to TM and pay that price... plus postage... for something you could get for under thirteen bucks.... Amazing Bill. Quote Link to comment Share on other sites More sharing options...
sub.z Posted June 6, 2007 Author Report Share Posted June 6, 2007 Sorry bill didnt mean to annoy Im going to see him next friday about a tank anyway Quote Link to comment Share on other sites More sharing options...
Pegasus Posted June 6, 2007 Report Share Posted June 6, 2007 No prob.... none whatsoever Forums are here to ask questions.. and to get answers.. and it doesn't mean you "have" to use the suggestions given.... it just seemed strange that was all. Good luck with your project Bill. Think this might be better in the DIY area...so have moved it there. Quote Link to comment Share on other sites More sharing options...

Lady-Lene Posted June 10, 2007 Report Share Posted June 10, 2007 I got some on TM called Rhodorsil V2. Says it is a Transparent, Waterproof Silicone specifically formulated for Aquariums. Cost $14 plus postage. (Not that I've used it - just got it in case of emergency) Pegasus ... I wonder if SubZ made the same assumption as me - that no prices were mentioned and therefore it must be EXPENSIVE! :lol: Quote Link to comment Share on other sites More sharing options...
Alan Posted June 10, 2007 Report Share Posted June 10, 2007 Bluetom said I've always used fosroc RTV, it claims on the back to be ok for aquarium use and is only $14 for a caulking gun tube, have used it alot on my tanks never had a problem. The price was mentioned, so add on the postage to the trademe cost.?????? Quote Link to comment Share on other sites More sharing options...
