mister crabs Posted January 15, 2007 Share Posted January 15, 2007 there is a guy on RC that used some sort of concrete mix and crushed oyster shell to make a rock wall on the back of his tank and it hides his overflows, returns, and it has little ledges to place frags. Just wondering if anyone had any input as to whether this looked like a good idea? (scratch) I think once it got covered with frags and corraline it would look WAAAYYY better than a painted back tank. heres the link : http://www.reefcentral.com/forums/showthread.php?s=&threadid=993625 Quote Link to comment Share on other sites More sharing options...
mister crabs Posted January 15, 2007 Author Share Posted January 15, 2007 the first part of thread is about Reef Ceramics which is prefab and is spendy. after that the guy talks about something called shotcrete. looks like the benefit of the mix he used is it doesnt take 6-8 weeks to cure like other DIY rock formulas. very interesting idea.

drock59 Posted January 15, 2007 Share Posted January 15, 2007 Ive been looking at the reef ceramics stuff for a while. So expensive but it looks so good. Quote Link to comment Share on other sites More sharing options...
impur Posted January 15, 2007 Share Posted January 15, 2007 They have the kuring time for DIY rocks down to about 3 weeks in this thread. http://reefcentral.com/forums/showthread.php?s=&threadid=952524 Quote Link to comment Share on other sites More sharing options...
Piero Posted January 15, 2007 Share Posted January 15, 2007 Ive been looking at the reef ceramics stuff for a while. So expensive but it looks so good. I've seen some really good DIY rock that looks just as good a that spendy stuff on those DIY threads. http://reefcentral.com/gallery/showphoto.php?photo=129851&papass=&sort=1&thecat=500 Quote Link to comment Share on other sites More sharing options...
mister crabs Posted January 16, 2007 Author Share Posted January 16, 2007 I like the reef ceramics but its spendy......i found another thread where people used that "great stuff" expanding foam and embedded rock and sand into it. supposedly inert once cured. but im curious whether its resistant to UV rays?

Ronjunior Posted January 16, 2007 Share Posted January 16, 2007 but im curious whether its resistant to UV rays? I had my 125 all planned out to make a huge cave/reef/frog/cichlid tank out of that stuff, but ended up doing saltwater at the last minute. You can use a morter mix with certain types of pigments too to coat the foam, but one mfg. rep told me some pigments are fish safe and some are not and can leach into the water. The one thing I see as a challenge with this stuff is making sure there are enough pores for bacteria and life. I've seen a 850g tank and all he had was a wall of that ceramic type of stuff, just hope he had a bit of live rock in the sump at least. Quoted from their Faq. http://greatstuff.dow.com/greatstuff/cons/faq.htm Can GREAT STUFF be used outdoors? Yes, GREAT STUFF can be used outdoors. However, cured foam will discolor if exposed to ultraviolet light. Paint or coat foam for best results in outdoor applications. Quote Link to comment Share on other sites More sharing options...
mister crabs Posted January 16, 2007 Author Share Posted January 16, 2007 yep...and i heard to paint it with the krylon fusion paint....but it wouldnt make it look any more natural.....maybe if you embededed LR and painted the exposed spots gray?

H20cooled Posted January 16, 2007 Share Posted January 16, 2007 That Shotcrete setup is awesome, I think it looks a lot better then the Reef Ceramics I don't like the big gaps in between the pieces. Quote Link to comment Share on other sites More sharing options...
