I have some advice you may want to pin to the top for others. I just did a reseal on a 20 gallon long on Monday it is now Thursday and the silicone is still tacky and smells like vinegar. I bought the GE Silicone 1 at my local Orange Big Box store, while at the store I did not think to check the date on the tube, nor did I think to check the date on the tube when I did the job. The date on the tube was from 2017 and it is 2021. Well after Googling if silicone expires apparently it does, this I did not know, and apparently the orange Big Box store had no idea either. So lesson learned , I'll have to take it out and redo it.

[@TrafishAquatics]

Good point, I'll pin it!

[@yadealone]

Wow so sorry this happened to you. I am fixing my tank tomorrow. will skip the big box store.

[@TrafishAquatics]

Just check the expirations, I've never had an issue and got all mine from walmart

[@chrispixx]

I just decided to post an update to this, the Ge1 silicone that was expired did eventually cure, and the tank is full and holding water with fish in it, but it took three weeks to fully cure. So watch those expiration dates.

[@TrafishAquatics]

I imagine the acetic acid was weak due to the age so it just took longer, glad your tank still sealed up

[@raisinmydog]

thank you for not doing video cuts/edits. This is what I needed to see

Bro, the fact that you did the close-up with the pieces of wood was awesome. Front start to finish, this was really awesome for someone who's never done this before.

[@island_Dave_KeyWest]

Thanks for taking the time, being so thorough and going slowly, step by step, explaining what and why for each step. I’ll be working on resealing a 20 gallon. Hopefully I’ll have beginners luck and it’ll all work out with good results. Thanks again!

[@NotoriousEmu]

Awesome video! I was given a 33 gallon and after filling it I discovered it leaked. So now I'm resealing my first aquarium. I watched a bunch of other videos but yours has by far been the best and most thorough. I really appreciate the example on the pieces of wood. Thank you for making this!

[@TrafishAquatics]

Your welcome, I had watched a bunch of videos when I was learning how to first reseal aquariums and nobody actually showed how to make the seal so I felt like it was a pretty important part to add!

Thank you Mr. Fish Tank Man, you have saved my college fish tank

[@eugenb.8448]

I’m about to do this. Thanks for the superb explanation and demonstration!

[@Nexuhss]

Great video. Going to reseal an old 140 gallon that I just bought. One tip for your viewers is to be careful using strong off-gassing compounds like the ones used in this video in the presence of a currently running tank. The oxygen exchange of the tank will pull those chemicals into the water and if you have more sensitive fish or corals, they can die. Thanks again for the video!

[@stephaniemadsen2497]

Watching your video gave me the confidence to tackle resealing a used 100 gallon tank I purchased. The video was very informative. I learn things best by watching others and this video showed me all the steps needed in detail to complete my project. I especially liked the wood block example.

@@TrafishAquatics A few years ago, I bought a 37 gal (made in 2011) for $5 at a garage sale. It held water on my patio a whole weekend, and then I put it into storage. I now have a stand for it, so I want to reseal in preparation for making it a kickass planted tank.

[@keepfocus121]

Thank you for your very detailed and instructional Video. Your video is truly helping me. I am currently resealing my first 75 gallon tank and I am taking my time and being methodical. Your close up shots is helping me through my resealing project . Example at 4:57 of the video where the tip of your blade barely touch or cut through the seam of the two panels, explaining not to go any further. I had to come back to this segment when I removed the first silicone layer. At this point, I noticed in my scrap that the side panel was beveled and silicone was in the beveled crevice. I didn't know what to do but I remember your point at 4:57 and I went back and stopped the presentation and looked at your corner tip of your blade which was close to the seam. I simulated the same affect on my scrap and I determined the silicone on the bevel could be removed as long as I didn't go into the seam. I hope when I am done this will be my first successful reseal. Thanks again for being informative.

[@jodidesjardins6341]

Perfect video. I just stripped the silicone out of my corner 55 for the second time because my husband put soo much on the tank the first time around, it was a mess and started setting before he could even get smooth it out. So, 5 out 5 on this one for showing the exact amount to bead into the corners thanks!

[@TrafishAquatics]

You're welcome!

[@royalspin]

Hate to say this but you'll probably have to redo it again .The reason I say that is because old sealant and new silicone don't bond well with each other . The best way to do it us to totally disassemble it,strip all the old silicone and use something like acetone to remove any old residue and then reassemble it making sure to get it between the glass panes where they meet at . I've rebuilt plenty of aquariums and made custom tanks and I can tell you from experience that this is the only way to be absolutely sure it won't fail . Obviously it's a pain to have to do this but then again having to break down your fish tank in a hurry and cleaning up the mess or having water damage to the house isn't much fun either . I hope it works out for you and that you don't have to go through that . Been there done that before .✌️

Thank you so much for this information! I have a 55 gallon tank that l bought used for 50 dollars. I have had it for about a year and it has started to leak on the front and back corners of the aquarium. I was very concerned so immediately put a bucket underneath the where the leak occurred and l lowered the water and moved my fish to another tank temporarily. I did buy another 55 gallon because l thought that it would be difficult to replace the silicone. Now l see that it is not so hard after all. I will remember what you did and possibly try this in the future Your a good teacher! And thank you for sharing this video!

You're very welcome and I hope that when you reseal the aquarium it works out well for you!

[@francisjoseph9642]

Smart to be careful of the odor and fumes for you, wife and your daughter. If doing it inside your home instead of in a cold garage in February, you could cover the tank with a sheet after you're done to keep fumes inside the tank and not in the room. Thanks

[@TrafishAquatics]

I do actually cover them from the fumes with a towel, for the first day if the tank has to stay inside to midigate the smell. On the 150 gal I just did i covered it with 4 towels. Works out well. I appreciate your concern though :)

[@yarasub]

Very well done and very easy to follow along, thank you. Just a little concerned, since I’m 71 having to take off the stand to dry outside or back into the garage. It’s fall here so its only in the 60’s and as low as 40’s at night ,will it still cure ? Thanks again😊

Have you ever done a full rebuild of a 100 gal or more before? I really would like to see how you do one. Still no leaks on my 180 but you never know when it will come to it. Thanks in advance

[@TomBTerrific]

Kudos! Very informative. You made it look easy. I know those who try this might encounter more difficulty than you did. One thong I was surprised by was that you never had to wipe you finger because of excess silicone. That I’m guessing comes from experience of not applying to much.

[@TrafishAquatics]

Yep pretty much lol, Ive done enough tanks to know how much is too much 😁

[@TomBTerrific]

@@TrafishAquatics glad you’re still monitoring comments. I went out and looked at my older tank I purchased. I can see where there was or is a leak. Unfortunately it looks like it penetrated the bond where the two glasses come together. It’s only about 1/4” long. My question is can I still go through the steps you’ve shown in this video? Don’t see any other questionable areas. Of course I would leak test the tank before bringing it into the house. I don’t think that void would affect the integrity of the tank. Do you? I would also mark the area and check for growth of delaminated area. I know you can’t guarantee just wanted your thoughts based on experience. Thanks

[@TrafishAquatics]

What size and where is the delaminated area?

[@TomBTerrific]

@@TrafishAquatics it’s right in the middle on one of the corner risers about 1/2 was up. I can see the mineral deposits between the joint. It’s only about the size of a green pea. I’m hoping that once I re- silicone the interior edges that it will be alright. Maybe I should make that leg up 3 times the with of the glass thickness. What do you think think? Thx

[@TrafishAquatics]

A simple resale could prevent that little spot from leaking, So it depends on what size tank, More volume means more pressure.

[@tenderizer6635]

Well I am glad I found this, because I just bought a used 120 gallon fish tank and was told it didn't leak when they took it down. However it does leak some so I am going to go ahead and reseal it as I had planned to from the beginning. This video has helped me with some of my fears about doing it. No way could I pass up on a 120gal tank for $100.

That is a good deal, good luck with the reseal!

[@blancamunoz8362]

Hello there ! Here from Louisiana ! If I bought a used tank and didn’t test it out yet, could I seal over existing seal with out removing any seal there? Thanks for your cool videos !

[@TrafishAquatics]

Unfortunately no, new silicone won't adhere to old silicone, you have to remove all the old and put all new silicone for the best results

[@PoseidonsPets]

Hey buddy! Very detailed video, thanks. I have a 90 gallon that spent a year outside in a shed. The seals are peeling back but I’m worried the silicone between the glass is shot. It gets to 120+ here in Arizona so not sure if simply resealing would be enough. What are your thoughts

[@TrafishAquatics]

Silicone is pretty resiliant stuff, the silicone between the glass is more protected between the glass than the seals are, chances are theyre fine, if you start seeing any air bubbles appear in the seams while the tank is full thats a sign that the silicone is letting go, my 300 was in my garage for almost 2 years through -10 winters and 110 summers and i simply resealed with no issues

[@PoseidonsPets]

@@TrafishAquatics thanks for the information. I figured it was fine but wasn’t sure

[@urwholefamilydied]

33:44 you could take it to your garage right away, nothing bad will happen. If anything it would be better to move it right away while the silicone is still wet, so it can cure in one spot without being moved.

[@humanman]

Hi. Very informative video. I just did this but I used too much silicone and the end result was not smooth at all. Now i don't mind it looks like crap but do you think it will still work if it's"bumpy"? I'm incredibly nervous. The floor is wooden so if it leaks it will be hell. I'm honestly thinking maybe i should just buy a new one.

[@TrafishAquatics]

Should still work fine, if your worried you can leak test it outside

Any updates on the tank? Am thinking about doing the same for my 55gallons remove the trims

[@zelphernide5758]

Great vid and explanation. I had no idea there was size marking on the tip of the tube. You said 3/8th but no marking for that size. Did you mean 3/16th? To me that seems like too small of a size for a 55g tank. I did like how you didn't have to tape up the bottom panel of the tank. Idk why I never did that. Makes sense of not needing to do the bottom because substrate covers it.

[@TrafishAquatics]

Thank you, the tube did have the 3/8 mark on it but on other tubes I purchased it didn't always have all the marking on them, just get it close to the 3/8 mark and you'll be ok!

[@erinvisser5046]

Just bought a 90 gallon, stand, filter and more through an auction. Saved a bundle, however due to covid I could only see pictures a head of time. Picked it up tonight and have spent the evening watching videos on resealing. It’s in rough shape, your video by far has been the most informative and I will be watching aging once I get supplies. The bottom black rim has also come unattached, do I use silicone with that or would you have other suggestions? I know that glass tanks depend on it for support. Thanks for your video and time.

[@TrafishAquatics]

Try to remove as much silicone as you can from the frame and then you can simply reattach it with new silicone and it should be good to go after a reseal!

5:00 im a little conflicted, i got a 75 gallon so the tank is a little thicker glass, but when i went do to do the reseals i did get a little bit past the the seam in 1-2 places, maybe a cm long, however, id say its no deeper then 2-3mm for sure did not go through the seem, just went past it slightly on some of the lower portions. it very much would be water tight once i reseal it. im mostly concerned about strength of it lasting.? watcha think

It would most likely be fine
