I have a new 36 gallon bowfront Aqueon tank that I bought for my puffer about a month ago. The water gravity is at about 1.01. My question is if saltwater is safe in any aquarium? I did read something in the start up guide that something shouldn't be used with salt water (I'm guessing it was the light). I felt some of the silicone sealant and it feels like it is a bit curved in. Is it safe for salt water to be in ANY aquarium? Thanks!
