300 dd marineland tank blows a seam

[Def Leppard Hysteria]

I don't believe back silicone is stronger then clear. the only issue I could see is if they change silicone, throughout the tank, it would show they seal tanks at different times

Our 3rd DD tank has clear silicone on the bottom....the previous 2 had black silicone throughout.

I bought a 40b it was dated july 2014, the black silicone literally peeled away from the glass with a finger nail and it was bubbling like crazy. I think it was a bad batch of silicone, got a replacement and it has been good so far...

This thread just scared the crap out of me for my marineland 180g with black silicone.

Marineland has had an issue with their black sealant.

I bought a 120g marineland tank lately from someone that went through the same disaster. They said once they drained the tank and started removing the old sealant, they noticed it was just disintegrating as they removed it. Its mine now so I will have to reseal it.

They contacted marineland earlier though and were told that it was a known issue and that they had recalled a lot of tanks made with the black sealant because of it. Not sure if it was a bad batch though or all marineland black sealants...

Yes. The third one has clear silicone on the bottom and black silicone everywhere else.

The first two did. We're on our third one right now.

ahh that's still a pain in the butt to deal with... i didnt use their stand so warranty is little bit hard to work on...

after having three of them failed I would let them replace everything, inform them this is the third failed one, and try to work out the entire package deal, tank, stand, canopy, then sell it all off and go with a 300 gallon acrylic or something different.
