|
Hi guys...
all's fixed and done... just waiting for the silocone to dry.
the new pane was fixed on Saturday night ... and now its approx 40 hours since its been drying there.
i checked this morning before i left to work by pulling the new glass upwards to see if its solid dried, but i could see the silicone move a bit beneath the glass on the sides' edges (as if it were still wet).
I posted [url]=http://indianaquariumhobbyist.com/community/modules.php?name=Forums&file=viewtopic&p=25571#25571]this[/url] new thread on the silicone i used:

Hi all...
i wanted to know which is the best silicone sealant to use for building Aquarium Tanks
This question arises after i just repaired my 4' tank's broken front pane.
[url]=http://indianaquariumhobbyist.com/community/modules.php?name=Forums&file=viewtopic&t=2958](click here to visit that thread)[/url]
the one i used was a brand called "CHEMMER"
it said 'germany' on the tube so i bought it and fixed a new pane to my broken tank ... it's transpatrent white.
i noticed the fine print: "made as Germany" only after i applied and was counting hours until i can start testing it..
it still doesnt seem to have cured as i check by lifting the pane to see if the silicone on the edges where the pane is resting, is still wet? and still seems it is.
also would like to know how elfy silicone (http://elfy.com/) is? i saw that at a hardware store and said its an premier indian brand! would it have been better than the "chemmer" brand i used?
well, waiting for your replies with my silicone covered fingers crossed!
|
replies would be appreciated...again 
btw, here a pic:
dum dee dum.... really hate the waiting game! more anxious than curious!

Wacker is just another brand of silicone... you don't have to add anything.
Don't do anything to your current tank... silicone does not bond to silicone. |

@shaji,
elastosil is a product from the company 'wacker'
and glass sealent is a product from the company 'dow corning'
both are acitic cure sealents - the glass sealent sets fast so is convinent to use for small tanks and the elastosil has a longer setting time and allowes you an extra tooling time for big or jumbo tanks

IMO, the joint is all that matters the stronger the bond the better results.
The second coating is just for finishing or smoothing the joint - I don't recommend any other brand of silicone to be mixed with the sealent you have used - go ahead and use the same tube - But, WATER TEST the tank before installing it in your house.

there u go, finally put the stand up in the garage and filled it up... its almost been 48 hours and still no leaks.... but there is a small issue i wanted to clarify.....
what u see inside are some river stones and an Amethyst Geode which i mined up a cpl of years ago. think i can keep open geodes inside my marine aquarium?
ok... he's my issue:
see the silicone glue through the glass? either its white in some places or transpatent in others:
the sides of the front glass which are stuck on the side glass edges...
is that normal?
im asking just to take the most caution... dont want it breaking and letting go and screw up the carpets inside!
Shaji
PS: i was also wondering if anyone sticks a vinyl transparent sheet on their aquarium glass just incase it cracks, to prevent it from exploding, i.e. |

Difficult to comment without physical inspection! But the colour variation seems to have come from the quality of the "silicone sealants" used.
Life of those joints may be short! So it may be a better idea to replace the side with a better quality stuff  . You may have little option once you populate the tank.
Considering the scaling and deposits that can arise from seawater, in your Amethyst Geode; especially with the multiple crevices and crannies-which will make it near impossible to clean; I would rather prefer it to be a show piece out side the aquarium!
Apart from this the geode is most probably inert and will not pose any other problem, provided it is not sharp -so as to hurt the fish.
I don't forsee problems with River-stones either, but either porous-rocks or live-rocks may be better option. |

The milky white curing of the silicone means that the silicone you used was contaminated with the white acrylic stuff used for sealing bathrooms.
Thre was a lot of this duplicate stuff going around Bangalore last year and many tanks failed.
Redo your complete tank, or else have a failure shortly again. |

daggammit! not again
today's the third day and the curing seems to be staying put... no leaks and no more white marks!
anyway, is the way to know that the curing has been done well is to see no white marks?
thanx for the amethyst geodes advice!
