Really nice setup. What type of structural issues are you having with the tank? I see that you said you got the tank before they stopped making that size, but how old is it? Also, does your Foxface nip at your corals?
There have been a couple structural issues that made me order a replacement. First, DSA used an epoxy to glue the cross braces to the frame of the aquarium. I noticed about 1/3 of one of the cross braces has no epoxy and I can see daylight between the brace and frame in that spot. I added an additional cross brace back in June and there have been no issues. I would have preferred the frame and cross braces be one solid piece though. I also recently noticed a little salt creep around the bottom seal as well, and I know that will not end well. The tank was set up on 10/31/15 and DSA is no longer in business to make a warranty claim.
Actually, I am starting to suspect the foxface of nipping but I have not caught him. I have noticed a couple corallites completely missing from a few acros recently. I’m hoping I bumped the corals while working on the tank, but I am keeping an eye on the foxface too. He is a great algae grazer, so hopefully I am just being paranoid. I think they are more likely to nip at zoas and lps, and I am having no issues with them.
