Probably less than might seem obvious.FishNCash;4074018; said:I'm curious if the direct sunlight UV coming in from the windows can damage the seal on an acrylic tank? Is this the same effect as tank sitting out side in the backyard?
squint;4079415; said:Decent quality acrylic usually carries a 10-yr warranty against UV-induced hazing or yellowing. That's for outdoor use. Indoors, there should be much, much less UV exposure that it should never happen.
Almost all acrylic aquariums are solvent welded, not "sealed," so the joint is basically indistinguishable from the panels in terms of chemical or physical properties, e.g., it's not more vulnerable to UV than the rest of the acrylic.
Still, I wouldn't store anything valuable outside in the sun if I had a choice. Exposure is generally not good.
