I'm refurbishing a Reef Savvy 40 gallon cube tank and when looking at the overflow, I noticed the below rings around the bulkhead holes. I did my first fresh water test and it held water for over three days. This tank has a layer of glass and a built in 'base', so I'm hoping it's just the way the base was sealed to the bottom...
Can anyone tell me if this is a result of old salt creep, or perhaps how these thanks are constructed?
Disclaimer: Please set aside comments on all of the clear silicone within the overflow, the previous owner apparently let a tube loose in there and I'm in the middle of cleaning it up. I might end up taking the overflow off and resealing it.
