No leaks. Maybe you should take a few days to gradually fill up your tank and watch for leaks. Let it sit full for several days, if it holds, go for it. If it leaks, most LFS
carry aquarium silicone. Note: I didn't notice any of the air bubbles in the actual joint creases. That might be a good sign. I'm certain that other AA members with resealing experience can give you a few pointers if you have to reseal. Good luck.
Thank you for your input.
The tank was in use by its previous owner up until a day before I bought it. He upgraded to a bigger tank and said he had noticed trapped bubbles in that aquarium at the time of purchase.
Since this tank was built less than 4 years, I contacted Marineland (aka Perfecto) and yesterday they informed me that they do not recommend filling the tank with water. They suggest I strip off the existing silicone and apply a new one. I went back and said this is a defect from production and they should be fixing it. I added me tampering with the silicone will give them another excuse to void warranty. Then they gave me excuses like since you're not the original owner of the tank the warranty doesn't apply. I thought that's pretty stupid and a ridiculous excuse for Marineland to offer instead of a resolution. It's irrelevant for them who the owner is. The original owner of the tank could have bought it as a gift for someone.
Anyway after further discussion they agreed to open the case file. Not sure what proposition they will come back with yet.
I better be safe than sorry. After all, nobody wants a large puddle of water in their home.
I was disappointed with Marineland for the way they handled this request. Had I not called in to follow up they would have ignored this case. Hoping for a satisfactory resolution. 🤞
