What is your plan for your tank then? After following a lot of these types of threads for the last few weeks it seems like the best bet is just to get a custom made tank. It seems like all of the big brand Chinese made tanks suffer from quality issues.Had this same issue with my 100 EXT. Got a replacement and now 3 months into the replacement tank, same issue.
I’ve contacted IM again, but do not expect they’ll be willing to replace tank again. Nor would I want another one as the design is obviously flawed and needs to be addressed.
