If anyone is paying the extra money for the All Glass Aquarium brand of silicone I might be able to sell them a bridge also!
|
GE and All Glass Aquarium have a "deal" going
|
Ya, 15 bucks is a lot to pay for a $5 tube of silicone. Especially if it's not black :razz:
|
I think that I'll try to get this one. Pretty pricey for such small amount.

I recently did some silicone work in a tank and got it from Home Hardware, 6.29 a tube. It is called Weather Shield, 35 year durability, and says right on the tube Safe for Aquariums.
|
As both Brad and Unclesalty mentioned, GE SCS1200 is a safe and very good choice. I've had many tanks built using this silicone and even recently used it on a bulkhead in my sump with only 24 hour cure time with no issues to any fish or coral including sps. I would recommend using it as long as you can find it.

Here's a quick question..
When you made the transfer, did you re-use the water or sand? or both? Maybe instead of blaming the silicone, it might have been the process of the transfer that caused the problem? Aussie Gold Torch, Neon Green and Blue Wall Hammer, Orange Frogspawn, Galaxia are definately susceptible to bacteria issues. I know I have lost frogspawns by just sand landing on them. The silicone with mildew inhibiter is definately a factor. I apologise if someone already asked. Ken - BWA |

Is it black? |

I used half of the water and no, I didn't use the old sand. I know it's the silicone for sure. This transfer was super very well planned and did everything way better than other previous transfers. Just for the record.....I have even lost some Ricordeas and mushrooms and these guys are almost indestructible. It's the silicone....I got in touh with GE and they confirmed that the silicone is NOT safe for aquariums. |

There used to be a Brock White in Burnaby -- Lougheed and Willingdon area. If it's not there you could try somewhere like Fastenal or Acklands.

Acklands Grainger should have Ge1200
or look up any store the Trade/Builers go to. Ken |

I did some digging and found out that All-Glass silicone is not made by GE, it is a product of DOW Corning. So I called the GE toll free line (866)-ASK-GESA and asked them about Silicone I (you get through right away). The answer I got was that none of the GE silicones are aquarium safe due to chemicals used and none are made to be continually submerged in water as the silicone will weaken. This being said I couldn't find anything about anyone ever having any problems with Silicone I but plenty of problems with Silicone II.

So the official word from GE is that all GEII silicones now contain petroleum distillates as a mildew inhibitor. Unofficially, this hasn't always been the case. My friend used to be a chemist for GE and he has told me several times now that only the Kitchen and bath version had this. He's surprised that we're even having this problem and didn't know abou the switch. So it seems they've changed it in the last year and a half or so, and this is why so many people have used it in the past without issue.
On all of the GEII bottles I have it says 100% silicone and makes no mention of the 1 to 5% mildew inhibitors. I guess it's too hard to write "95% of this product is 100% silicone". Previously only the GEI and GEII kitchen and bath had the inhibitors; seems like the "premium" line of GEII only now carries his option. When I chose GEII for my tank I did so for strength and quality rather than price, and on the recommendations from several reefers and a guy who used to work with the stuff. The chemistry behind GEII allows for a better bond to glass and has less tendency for the inside seems to peel away from the glass with age, so you don't get the tattered look some old tanks get. It also has more give to it while being stronger and has better resistance to the elements (ie. Salt water). This formula though evolves ammonia rather than acetate; however, it is "supposed" to cure much faster. It is spposed to be minimum 3 hours to water ready, 8 hours to moderate strength and 24 hours to fully cure. Bare in mind this is not accounting for the evolved ammonia to dissipate. I've seen several threads where people make emergency repairs with GEII and fill the back up with water in 8 hours without I'll effect. Most tanks "should" be able to handle the relatively small cycle caused bathe ammonia is there was some still there. When I built my tank I let it cure for almost a week and a half, filled it with water for 48 hours twice and gave it angood clean... And I still had a problem when I transferred, so I doubt it was the ammonia and likely an effect of the inhibitors. Big tanks probably notice this less due to dilution. Had it been more readily available to me I would have gone with a RTV silicone that was aquariums safe, but since it wasn't GEII was the strongest, supposedly "safe" product available to me. When I swapped my tank there were 7 other more probable causes for my problems (temperature swing due to a faulty heater, reusing old sand, broken skimmer shaft so only a small back-up skimmer, etc), so I never suspected the silicone. Seeing what is happening in this tank and having got this other bit of info this morning from GE, I am more suspicious of GEII being the cause but bottom line is: it's officially not reef-safe. The inhibitors may have caused die off of microfauna which may explain the ammonia spike, rather than ammonia from the silicone itself. If anyone is reading this and having problems with GEII, run lots carbon to remove the inhibitors that may be leeching into the water column. The direct effects of whatever was happening seemed to dissipate within a couple weeks in my tank and was just a long road to recovery. They tank is healthy and happy now and the corals are growing like weeds like nothing ever happened, so it doesnt look like there are major long term effects from the silicone (if that was the cause), just an initial hit. |

Anyway, I finally got home after running around the city all the day picking up stuff that I'll need to shut down the tank and remove the silicone. Wish me luck. |
are all your corals ding well now, how longs it been, GE emailed me back and said the Mildew inhibitor in Silicone II lasts for 5 years. Im wondering if this effects the reef. My tanks has also recovered except a couple corals (one acan/one duncan) its been over a month.

I've only ever used GE1 and let it cure for 2 days,zero problems or loses.

Mid November I was correcting the tank for low mag by slowly dosing over the course of a week and a bit (going from 1000 to 1300 ppm over 9 days). Near the end of this I had a bunch of brittle stars "die". Some died, most recovered. I suspect this may have been from dosing with magnesium sulphate heptahydrate (which can anesthetize inverts) rather than mag chloride/mag sulphate. Brittle stars seem back to normal. I would say it's been almost three months and everything is back to normal except for my duncan and a monti (which is on the mend). The duncan never really opened again and a few weeks back it just died in a matter of days. The monti cap has been looking rough but has been growing; it seems on its way back to health. Overall, I'd say within a month to month and a half things were more or less back to normal but my nutrients were still high (nitrates ~10 ppm). After 5 weeks of vodka dosing my params are near zero and that alone has seemed to have had the greatest impact. I have full PE on all my SPS and everything seems to be growing nicely. Over the early few weeks of the whole ordeal I had the symptoms of a cycle (diatoms, etc) but never detected an ammonia or nitrite spike despite testing daily starting on day 3, so I was at a loss at to what was happening unless I missed a spike on the very first day. So the mildew inhibitor affect the reef? Well, as you can see from this thread and yours and my experience, yes. Long term? I can't really say. My new tank now seems healthier than any system I've had before despite a few healing war wounds and the growing pains of a new reef. Over the past 4 to 5 weeks I haven't seen anything that would suggest that it is still having an effect on my system. |

Very sorry to know your loss, Daniel. I am wishing you have a best luck this time. |

Thanks for your encouraging words. I have learned a costly lesson here. Do your own research and never trust anybody entirely. Thank is being shut down as we speak. I am not going to wait a few weeks hoping that everything will be ok or better than ever. |
Wow that sucks , sorry about your corals. I just set up a cube that i re-sealed with black ge silicon 2 and even after compleatly drying out my live rock so i could epoxy it , there was minimal amonnia . I have tried to introduce a couple of sps frags only to have them bleach and rtn though.If ge is really putting extra stuff in there 100 % silicone im p***** how is it 100% if theres other crap in it.

Lessons that I had learned was always costly and followed with painful memories. Anything bad that has happened to you recently, just think it will be left behind this year. The new year comes to you in a few days, I am sure you will be able to set up a beautiful tank again. |

Stay tuned and check the livestock and equipment forum in the next few days or week(s) as I might post all my livestock and equipment for sale. I still have some really cool corals (lots of colorful Ricordeas, zoas...etc) that could be up for grabs soon. I feel that perhaps it's time to move on.....am tired. |
PMs sent my friend.
Don't give up. Maybe take a breather but even though sometimes this addiction can beat us down with stuff like this, I believe that you can overcome this setback and create a new tank that will blow us away. Anthony |
Just an FYI, I found the tube I used and it was the Window and Door stuff...about 14 months old...crappy that they can change the formula, since I would also tell anyone it's fine, having used it myself..

Hang in there. No need to rush. Keep the corals/fish in your holding tank a couple months if you can keep them "healthy."
I talk from experience. I just went through 18 months battling dino's. Anyone who can bring a vision to life as you did has a true talent. Keep your livestock in a minamialist set-up. If you have the knowledge, equipment and livestock you will get the bug again soon and make a full comback. |
Did the GE1 recipe also change?
It was GE1 Window/Door I believe that was always referred to as reef safe (far more often than GE2 Window/Door). I used GE1 clear when I resealed my sump. Tank is doing great but I do have strange NEON YELLOW growth on the silicone only lol...? |
Shiotty deal.
Goes to show that sometimes it's better to spend your money on the proper stuff then find out you should have later. Best of luck. But are you positive nothing else could have caused it? I would feel if it was leeching into the water, then it's probably already absorbed by the rocks and whatnot. Might be too late for everything if that's the case. I never read the whole thread, but I assume you tested all your parameters. Crappy. Again, good luck. |
