Hey guys and girls I was rearranging my rock to put a SCWD in my tank and did one of the stupidest things thinkable. I sat one of the MH retros on the glass at the top of my tank and while getting everything in my tank BOOM I left the light turned on and the heat must have broke the glass support. Do you think if I just have a new piece of glass cut to replace the old one I can cut the old one out and replace it without needing to drain the tank? I have attached some photos so you can see what I am talking about.

I have some extra 3/8" glass, pretty large pieces that I could trade and you could have them cut to spec, it would be cheaper. I just priced some 3/8 glass for a 20x 12 piece, 20 bucks, i don't even want to know what you're is going to cost. I think this is is replaceable, it's on the top right? PM me if you are interested in some glass, I have some nice pieces from a 55 long I busted a small panel on. Keither ------------- My bubbles.... He likes Bubbles. |

I would also think that you could just drain some of the water and be able to reinstall a new support. ------------- Contact me for professional aquarium maintenance and localy grown coral frags. [URL=http://www.aquatitranquility.com][/URL] |

Yea that�s about how big this piece is it is 24x14 so probably about $30.00
Yes it is on the top right side. Do you think I should drain about � the water before I try this? I am so worried about having 120 gal of water on my living room floor.
Also if anyone is willing to help me I would be willing to pay you a bit for your time.

ufortunatly I see that the old sylicone wouldn't mate to the new sylicone on the new top. So you would have to keep your water level lower in the future. GOOD LUCK. Thats a TALL tank to be pulling the top off. Maybee build a jig so it won't spread before you pull the glass. Central glass usually will cut glass to whatever you want....

I think if you cleaned off that top silicone really well and just replaced that small side. Or, just silicone a piece of glass right to it on top to reinforce it, it's not cute, but it would help. PM me if you interested in some glass of mine. I owuldn't mind helping you just to check out your tank! I have a couple belt clamps we could throw around the top of the tank while the top corner was being replaced. I agree with S too, you may need to lawer the water a bit. -Keither ------------- My bubbles.... He likes Bubbles. |

Keither you have a pm. Anyone see a problem with just siliconing a piece on top?? (That was my original idea but didn't know if it would hold.) I am going attempt to fix it tomorrow / Monday. I got a few cable�s and adjustment thingies <- �technical term�. Hopefully this will go ok! If not you will see hear on the board in tears looking for a new �cheap� 100 and something gal tank. Well everyone wish me luck. -=J=- |

I didn't think of adding a second toper. Thas a GOOD idea. Sylicone the snot out of it do it is as close to having no bubbles as possible. sealed up terariums this way. ------------- I will just give my warning that your system will flood, bulbs will burn out, and things will take continuous maintenance... get over it.

Those are better pics than the first ones you sent to me.
Since it is holding currently, I have to ask whether the piece is even necessary in the first place. Most glass aquariums do not have those kind of top supports. Only acrylic needs that kind of support to keep it from bowing out into a round plastic bubble. 
If you have ever removed the plastic frames from a commercially manufactured glass aquarium you will see what I mean. And the plastic frame is not to hold it together, but rather to protect the edges from bumps which could compromise the glass. My opinion is to remove the broken glass and enjoy the more open top access. Also, please update your phone number with me for my records. I called and started talking about sand, rock, and cracked glass with someone that thought I was crazy! j/k  , but I do need your correct phone number.------------- Reefkeeping Tips, & quick, easy setup tricks: www.utahreefs.com/forum/forum_posts.asp?TID=9244 Pay it forward - become a paid WMAS member

I agree that the "added support" of that piece is probably unnecessary. A piece laid on the top and secured with silicone offers zero structural value. But, if you want it just to have it there go for it. ------------- In Syracuse "I believe that forgiving them is God's function. Our job is simply to arrange the meeting." - Gen. H.

Ok guys I got a piece of glass cut yesterday and was planning to start doing this all today. I have also wondered how much that glass around the top is really for support and how much is just to hold lights up. Any one else think I would be safe just removing the broken and not silicone the new piece on? |

I couldn't hurt to have the extra "just-in-case" support. But I don't think that it is needed for the integrity of the tank. (If it was, I think you would already know by now  )------------- You shouldn't be afraid of noises in the dark. Anything that wants to cause you harm will stalk you silently. |

I disagree. I think you will want to replace the top support. They don't put them there for fun. ------------- Jake Pehrson Murray http://coralplanet.com" rel="nofollow - coralplanet.com http://utahbeeranch.com" rel="nofollow - :) |

I am just going to replace it to be safe. However I have never seen glass tanks before with these top "supports". Who knows. But better safe than sorry.

Of course, that's the safe way to go, especially since it is a homemade tank.
But looking at the pic of the top and how it's just siliconed to the top edge makes it less structurally supportive than if it was siliconed inside. The way it is currently the silicone can curl and allow the vertical pieces to move. Curling could more easily allow the bond to break. If installed inside it would have to pull more directly and from my experience, that's a movement not so easily allowed by silicone. Sorry to add questions and technical mumbo jumbo to the mix. Just my two cents worth, that I couldn't resist throwing in. ------------- Reefkeeping Tips, & quick, easy setup tricks: www.utahreefs.com/forum/forum_posts.asp?TID=9244 Pay it forward - become a paid WMAS member

| Glass aquariums have either a plastic or a glass perimeter to keep from breaking. Obviously height has a lot to do with whether the brace is needed. I have taken the bracing off of All-Glass and Island tanks only to replace it with acrylic bracing. I built Arjen's sump that is under his 225 gallon in which I did this. Maybe it is needed, maybe its not, but its not worth the gamble to me. I would either fix it or replace it with something else. I would not leave it open without a brace. |

Of course, Marcus and everyone is right, better to be too strong than not strong enough.
I was looking again at the amazing cracks. Did it crack all at once and make a terrible sound? You said "boom"? And did the pieces fall into the tank? That must have been scary, and if it were me, I would have stood there wondering if the side would pop and water would come gushing out, like in those movies. ------------- Reefkeeping Tips, & quick, easy setup tricks: www.utahreefs.com/forum/forum_posts.asp?TID=9244 Pay it forward - become a paid WMAS member

Oh yea it made a terrible sound almost like someone shot a 22 in my front yard. The broken glass did fall into the tank and I still don�t think I got it all out (I keep thinking my Mandarin Goby is going to be looking for food and slice him self on a piece hidden in there somewhere). Needless to say I stood there scared to move for a second. Scenes from Duce Bigolo popped into my head and I was trying to think of what tupper ware/buckets were going to be fastest to grab. Boy was I relieved when nothing else cracked!! I noticed today when I was going to put on the new piece that I got 3/8 and the old glass is not as thick. That reminds me I think jfinch said what caulk will be safe in our tanks anyone know what kind it was? I will be cutting the old sealant out and adding the new glass in the morning. |

I've had good luck using GE Door and Window 100% Silicone I. I noticed Home Depot now carries Aquarium Sealant in a small squeeze tube (kind of expensive). For this small job it might be a better option. ------------- Jon https://www.youtube.com/channel/UC6y_EzjI_ljbIwf2n5uNzTw" rel="nofollow - What I've been doing... |

I had Silicone II peel right off of an overflow I made twice. I think it was because I was bonding acrylic to glass, not glass to glass, but who knows for sure... From now on, I only use the Aquarium Silicone that Jon mentioned. |

If you use silicone or sealant or anything else, make sure that you keep the area really well ventilated until it cures. I've heard stories about the fumes killing the livestock on stocked tanks like that. Good luck! Brian ------------- Provo, Utah |

For the amount of silicon that he needs in that area, it would be good to ventilate with a fan as Meeshi_ma said, but the livestock will be okay and water can even come in contact with it after 24 hours and cause no problems.

Jburse, I didn't mean that to come across wrong. Sorry... It just made me laugh to think that a 22 Cal rifle is loud. Maybe "terrible sound" was not referring to the volume of the shot. Oh well, sorry to get off track. |
