I feel partly to blame. My equipment is red sea. I give them money knowing what I know. I have found their customer service on that end great. In they sort of knew they had a faulty product, sure they didn't own it, but they gave me zero push back on replacing an out of warranty part.
I am going to assume that to change the stylings of the tank is going to cost them millions. I bet they have specialty equipment made just for assembly and to change this assembly line would be very costly. I think they have made some smaller changes, but it seems G2's fail a fair bit too. If we knew how many tanks they sold a year then we could see if this failure rate is within spec given customer error and install issues. I'm guessing they sell 200,000 a year maybe. If they have 500 failures then that's .25%. Not bad for having more than 10% of the market. Just playing devil's advocate.
