Same with Red Sea, I’ve seen so many reports of tank fails I lost count. Company blocking and erasing post, emailing people not to go public, just weird overall. Cade is also manufactured in China so I would go with SCA or Glass Cages if your in the US
Yes you have seen Red Sea Tank fails and many other brands. RS Facebook were you have seen this isn't for warranty and rants and those posts are directed to Tech Support. Their FB is for reef discussion. Truth be told most failures are from user mishandling of the tank, the cabinet not assemble properly or level and mostly glass cleaners damaging the seal. How do I know? Because my Red Sea Reefer 250 seal is going out now! Its probably from me scraping coralline and damaging the seal. Serial number 30,000 plus. They have dozens of models and have made over 30,000 of just the 250 liter. I think they know what they are doing.
Anyways I would never buy anything but Red Sea. They have best best customer service in the industry bar none. A 3 year warranty. I think you can buy an extended warranty now. My replacement tank was delivered last week at no charge and no questions asked how it happened. They just wanted some pics. Red Sea!!!
