Rena/Mars Fishcare is the worst company I have ever dealt with. The customer service is a joke. If you can get someone to answer the phone or return your messages all they will do is make you jump through hoops until you are so frustrated you just give up. The whole time your fish suffer. I purchased an XP filter and it quit working after 2 weeks. You're better off spending your money on ANY OTHER FILTER
