jamesbarr Posted March 17, 2012 Report Share Posted March 17, 2012 hey all, looking for some ideas for the 36 tal that I just relined today. I was thinking about siliconing a cave together with various rocks and putting a kind of pot on top for some kind of plant that would otherwise take over the tank if not controlled. I thought that it would make piece to surround by vals or some other tall plant so you would see the contained plant mixed in the tall and the cave in the midst in the back corner of the tank. so the reason that I thought Id write about it is to get some feed back about the type of adhesive to use. The only aquarium safe stuff I know of is silicone. but it seems that it may be a pain to get it to hold fast enough to get it all together. Has anyone got any experience with this sort of thing? Thanks for that help Quote Link to comment Share on other sites More sharing options...
jamesbarr Posted March 17, 2012 Author Report Share Posted March 17, 2012 p.s. thhe pot thing i was referring to was going to be made from the same rocks as the cave. in case someone thought id be attaching a clay pot or something....

ckmullin Posted March 17, 2012 Report Share Posted March 17, 2012 (edited) silicone. funny you mentioned this. I've started a thread to solve your problem. http://albertaaquati...showtopic=36149 Search google for super glue in an aquarium environment. I've read stories about people using it for such things. quick note: if you use silicon and the set time is longer...use a form for your creative display until it holds. Even crumple up some newspaper and use tape to create the perfect form your looking for. Edited March 17, 2012 by ckmullin Quote Link to comment Share on other sites More sharing options...
Vallisneria Posted March 17, 2012 Report Share Posted March 17, 2012 I've used silicone to attach my rocks together and make caves. Works ok but even the clear silicone turns white after a while of being in the tank and can look a bit bad. So I wouldn't suggest slathering on a ton of silicone. I made my caves so they mostly stood on their own anyways. The silicone was just to tack the piece together so I didn't have much that was visible, but the silicone there is turned an opaque whitish color. Not the prettiest. A solution for this might be to put sand onto the silicone before it dries so it looks nicer and more natural. I think there is also an aquarium epoxy that salt people use to glue live rock and stuff. Its probably more expensive then silicon. Crazy glue is aquarium safe but I dont' think it would really work to glue a rock cave together. Quote Link to comment Share on other sites More sharing options...
PistolPete Posted March 17, 2012 Report Share Posted March 17, 2012 i use black silicone to make caves all the time. I find that after a year or two its not as sturdy. My elaborate creations last less than a few months Quote Link to comment Share on other sites More sharing options...

jvision Posted March 17, 2012 Report Share Posted March 17, 2012 I made a Journal Entry on a tank I did just what you're talking about. I used waterfall foam, sold at Nature's Corner Store Quote Link to comment Share on other sites More sharing options...
