During the final stages of my move one of my larger aquariums sprung a leak.
This can be a very stressful and alarming time for any fish keeper, so I hope this video helps you be prepared for if it happens to you.

The new fish room is so beautifu!!l The tanks look fantastic and I love your artwork across the back of the wall!!! What a great tutorial for resealing aquariums!! You always explain everything so well and in detail!! Thanks for sharing with us 🙏❤️ Awesome video and I had to rehit my Notification Bell🔔 Hope you and your family are having a wonderful holiday season!! Much love my friend 🙏🌿🐟🌿💚

[@BlakesAquatics]

Great to hear from you and thanks, glad you like the new fishroom. Will always be a work in progress but definitely an improvement 👍

[@pelhamsaquatics]

Welcome back my friend! This video timed very well, I have 2 - 40 gallon breeder tanks where the silicon is receding , not leaking but I’m thinking of resealing them before the crisis happens. Thanks mate🙂👍🏻

[@Pinky_OG]

Thanks for the tips and tricks ! I am going to re seal my tank tomorrow. I got the silicone today. I’m nervous. Never attempted anything like this before.

[@BlakesAquatics]

Good luck!!

[@aquamate]

The room and backdrop looks so good, well done man, also great info looks good too

[@AmazonasBiotop]

Thanks for a great video. One note is if you use a miracle cloth with alcohol then the alcohol will dissolve some of the "miracle things" in the cloth. I used IPA and got gunk left behind and a destroyed cloth.. :)

[@BlakesAquatics]

Good tip 👍

Ace tutorial mate. Very helpful. 👍

Love the new fish room 💃🏼💃🏼💃🏼

[@caleb8677]

Good to see you back at it mate, hope the move went alright and that was the only tank that sprung a leak 😜

[@BlakesAquatics]

All up i had 1 leaker, 1 cracked and one corner chip that i repaired with epoxy. Not bad for 50+ tanks i reckon 👍

[@caleb8677]

@@BlakesAquatics yeah that is a pretty good outcome for that many, plus you got a video idea out of it

[@crossbreedflowerhornsworld8143]

Nice video Blake!

[@robertfong-mow7235]

I did this already about 2 yrs.ago. Same size tank except 20 inches deep. Pain in behind to move around. Glass is heavy. Now it's leaking again. I think this only works for a pin hole leak. You need 2 people to move a tank that size around.

[@BlakesAquatics]

Yeah for sure

[@onemillionfish]

i just cover everything in flex seal. thanks Billy Mays

[@VinnysAquatics]

Well done brother 👍👍👍

[@Fishcentral]

Although this is not a problem for me right now, it’s always good to know what to do in a situation like this. Great video Blake, 👍🏽👍🏽😁😁

[@pecosR0B]

If the inside is properly cleaned and silicone re-applied, do I need to worry about removing the silicone from underneath the metal frame? I don't know why there is silicone on that side but I had a big leak around the base/black frame of my 40 gallon over last weekend and need to reapply silicone. I'm assuming if I do a good enough job on the inside of the tank I don't need to worry about the outside.

[@BlakesAquatics]

Correct it shouldnt matter

[@Shananana99]

I resealed my tank and there after putting water in it, I noticed little bubbles under the silicone. I let the water sit a few days it hasn’t leaked. Would this mean there is a leak in the seam or just a crumby sealing job by me ? Any advice? Thanks

[@BlakesAquatics]

A little bit of a poor seal job. I have tanks like that too just keep an eye on it and if it doesnt get worse its generally ok

[@thebluphynix7179]

On a framed aquarium like you would buy from a store, do you have to take off the silicone on the top as well? I assume so.

[@BlakesAquatics]

Yes 👍

[@thebluphynix7179]

@Blake's Aquatics I thought so, thanks for the quick response !

[@kilrkitty0818]

If I have an old tank about 10ish years old that's not leaking should I go ahead and reseal it? If so, should I just did the area you did and not the structure (I hope so) lol

[@BlakesAquatics]

I am lazy so if its not leaking I dont bother 😄

[@Galaxy11.11]

How has the tank held up? My mom gave me my childhood fish tank it's about 20 years old. Its 60 gallons and there are no leaks but the silicone looks like it was chewed by a rat. I've been reading allot about this and there is so much mixed information. I've read that the old silicone won't stick to the new silicone. I'd rather not take the whole tank apart. I also don't want to mess with it because it's not leaking but it's so old that I'm concerned about putting water in fish in the condition it's in. I read that the old silicone will repel and push out the new silicone. I'm not sure how true that statement is though. So I'm very curious to know how this tank has held up.

[@BlakesAquatics]

The tank is still leak free. Ive done plenty of each way; just resealing inside the tank and also removing it all. Resealing internal works fine for most tanks

[@Galaxy11.11]

@@BlakesAquatics Okay thats good to hear. I'm going to give this a try. Thank you for letting me know. I really appreciate it. Have a great day! 😊

[@derekgladden5200]

Did everything hold long term

[@BlakesAquatics]

Yes absolutely

[@blujeans9462]

With recently refinished floors, I've been deathly afraid to set up my 'new' fish tank - maybe someone can give me some confidence to start (yes, I have a tray and water absorbent material under the tank - should the leak be minor)? I am not confident only because, although the tank has never seen water, it has been 'in storage' for about 8 years; first in a dry basement, and the last 2 years in the house - with the last few months in the room it will reside in. What are my odds of it not leaking? I plan to fill it up (all the way?) and leave it there for several weeks - then drain it and start the aquascaping, assuming no issues arise. Thanks for your thoughts!

[@BlakesAquatics]

You want to reseal tanks about every 10 years so id definitely give it a refresh if its been dry that long

[@blujeans9462]

@@BlakesAquatics Thanks! I'll follow the instructions in your video. :-)

Is there a good time to drop my tank off for repairs mate.. 😂 Nice to see a vid.. 👍

It's about 10cm hairline crack on the side panel middle of the panel. It seems to just be on the inside and not leaking.... would you recommend doing anything to it or just leave it?

[@BlakesAquatics]

Yeah id brace the top of the panel immediately. Id also the consider some epoxy over the crack to stop it getting worse

[@madhatterjones4781]

@@BlakesAquatics what do you mean by brace the top?

[@madhatterjones4781]

@@BlakesAquatics it is a rimless 60cm tank. Is not set up yet. I was cleaning it to get it ready for set up. I am thinking I will get the side panel replaced?

[@BlakesAquatics]

@@madhatterjones4781 yep thats what id do in that case, i meant just silicone a strip of glass across the top of it but if its rimless you cant do that obviously
