Title: Motor burns out/Parts difficult to find.
Review: Purchased the system 6 and hex 5 for the grandchildren about 2 years ago,Both units are good for a few small fish and the bio system does a good job. The pump motor is starting to actup. Needs a replacement.(hex 5)Can't complain at least it ran 2 years. The system 6 I have replaced the pump unit twice in two years. Both time it just stopped and refused to work.(kept the water at the right level). They are a sealed unit so repairs are out. Marineland is of no help. Imported from China? The filters are just as hard to locate.If not for the internet and help from online suppliers You would end up tossing them out.As one other reviewer stated for the price, you would be better off with a 10-15 gallon conventional setup. Make sure you purchase products that have a good customer service and parts available. I don't recommend marineland.
