I spoke with Steve and I have to figure out what to do with the extra tank. He is shipping a new one today. I really appreciate this kind of customer service.
I will have to do a deeper inspection to see if it is stress cracks or scratches. I didn't want to touch anything before i got confirmation that a replacement was being sent. Time to pull off the black plastic cover and take a deeper look. I really cannot imagine why there would be so many scratches on the inside of a tank, when it is drilled from the outside. It really seems like it would be cracks.
I actually bought the euro braced version because its drilled for the 16" overflow. I did this because i contacted Synergy, and they implied that it would take 6 weeks to get a 20" overflow built for me. Being that I didn't have 6 weeks to spare.... Now, ironically i am past that 6 week deadline. Yeah, i know that I should know better by now. Nothing happens as expected in this hobby
*Fingers crossed* on the next tank arrival!
