so... buyer beware!!!
Red Sea has a disclaimer right on their site, that I never knew, cause all other items I ever purchased, the warranty goes with the item as long as you can provide proof of purchase. Well, Red Sea is not the case. Their warranty applies only to the original purchaser. So, I'm out several hundred dollars on a replacement tank but the new tank will come with full warranty. 2 on the glass and 3 on the seals.
As much as it frustrates me and makes me sick, they are just adhering to their policy. However, they were very responsive to the matter and going to try to get out one of the door tomorrow to get to me asap.
so beware of buying any Red Sea tank second hand and understand that it doesn't matter the age of the tank, nor if you have the proof of purchase.
