Come to think of it I actually spoke to the LFS I purchased the tank from first and they said I was on a list of purchasers they needed to call. They then asked me to register the tank and they contacted the Red Sea rep to make sure he then contacted me, which he did via email. I’m pretty sure Red Sea contacted stores in Aus to make sure XXL750 owners that they had sold to were notified. Sorry it was a while ago now lol
The tank was up for 15 months, but I am not sure when the bubble appeared. I only noticed the bubble when I was up close, installing the retrofit support kit. Thankfully I caught it before it failed!
No, just the tank and piping. However, it appears that I had Version 1 of the 750 XXL and the replacement tank is Version 2. After closely looking over both tanks, I noticed there has been some structural upgrades in V2. Specifically, all seams now have a reinforcing brace/silicon protector. With the addition of this seam brace, it effectively increased the silicon seam from 3/4" to a full 1". And the piping was included, according to Red Sea, because the bottom glass is thicker, but I haven't confirmed this yet.
I wonder if the reinforcing brace is common to all of Version 2 750 XXLs, or if this is a recent update due to the seam failures? And, are the failed 750 XXLs tanks ones without the silicon brace?
It certainly appears to be, I've just helped swap out a V1 for a V2 and there's a definite difference in thickness.
Does it have the plastic trim/armour like the bigger tanks?Look what is starting on my 250.
It's certainly a major headache. My mate is lucky to have a good support network, our LFS baby sat his fish, some of his corals and loaned him a load water containers. Another friend lent him a couple of big koi trays to put his live rock in. He was able to get a few of us in to help shift the tanks about. I'd hate to have to swap even a small tank about without that.
Rimless and braceless is not an issue if adequately constructed. I think these issues, particularly in the larger models, are a combination of problems. With the way they've done the base-side join IMO 1/2" glass should never have been used for the base, the rest of the tank is 3/4". It's not just a glass strength issue but rather sq in of bonding surface. Going from 1/2" to 3/4"increases the bond area by approx 33%. Combine the long unsupported span above the sump with the more flexible (vs 3/4") 1/2" glass, narrower bond line and you've got the risk of extra stretch of the bond line.
You can totally see coraline and reg green old algae growing between the glass and silicone. No sand In My tank but I assume it would be there too. If it gets worse I’ll have them warranty, they said they would and I have another 2 years of warranty left, tank is only 13 months old. We will see how they handle it if and when that time comes. I swear this was not there 4 months ago. Still love my Red Sea tank. It’s the nicest one I have since I started SW back in 2001. Had a reefer 170 for 2 years previously and loved that too. When I ever get money to upgrade I will most likely get another Reefer. My first tank way back in the day was an oceanic 55 gallon that had hardly any silicone on it from the factory and never leaked but it had a rim. I did forward the email of the Red Sea reps assurance of the issue not being a risk to my homeowners insurance. He has a couple tanks at home and confirmed that my current insurance will cover me 100% and they can go after RS. My only real concern is of my animals if something happened. I have no back up tank to put things in and no close to me fellow reefers.
