Thank you! The hex was about 4 years along in those pics. I was just getting into SPS.Wow, you had a great looking hex build!
I hope the bubbles aren't anything to worry about. I'm about 85% ready to buy the same cube and I'm a bit nervous now!
I'm not too worried about the bubbles they seem to be staying isolated to the top 6 inches of the seems. I'm going to leave the water in for a bit and see if it gets worse. These tanks come with a lifetime warranty ( if you use one of their stands) so I think it will be OK. I built my stand and it's much stronger than theirs. If they are willing to guarantee the tanks the seems should hold.
