Not good, what did RS say?
The tank is 7 years old, well outside warranty…

I put a mark on where the separation is currently, i will get a ratchet strap tomorrow and visit my LFS sometimes next week. Also waiting for answer from Red Sea
How is this tank doing?

Strapped together? Or (hopefully) drained of water post-livestock transfer?

Good sunday everyone!

I just recently discovered this on my seam, a few days ago.
Tank is a 7 year old red sea reefer, does it look worrying? It just barely reaches the waterline. Can i leave it and keep an eye on it? Or can i put something to reinforce it?

I have contacted the red sea customer support as well, lets see what they will say.
I can guess what they'll say since it's outside the warranty.

It looks to be failing like my reefer 170 after 6 years.



I decided to remedy the problem myself.

This is my reefer 300 still under warranty.

And Redsea response to my warranty request. Not that I would fill another RS tank in my home but i did want to see what they would say.

Hello David,

Our team has thoroughly reviewed all the photos and information you provided. We can confirm that the seam protectors of your aquarium are functioning properly, and we believe your aquarium is not at risk of failure.

Your aquarium has 1/4-inch (7mm) seam protector strips installed along the bottom and vertical seams. These strips serve as a protective layer for the seams of the aquarium, helping to prevent damage to the main seal that holds the glass together. This damage could potentially occur from cleaning the glass, normal wear and tear, or from algae and crustaceans that burrow into the seams. The measurements in your photos confirm that the structural seams are intact and that the integrity of the aquarium remains unaffected.

We encourage you to monitor this area from time to time and keep us informed if the separation spreads or changes to exceed the quarter-inch mark.

Looks like a nice mature tank. Sorry to see this. It's bad enough when it happens early on.
This is my 300 . I'm not looking forward to moving all these coral out 😥

I just got really into reefing about 2 years ago now, before it was just chugging along a bit with the leather and kenya trees.
Sad to see it, but at least we used the chance to upgrade to a bigger 540L tank, which should arrive in 3 to 4 weeks.
