With a few parts here and there I've kept some upwards of 10 years. Why buy a new one when for 10 bucks you can make it keep going?
I have a c-360 running and in fact just ordered another one... great filter... no leaking issues... however it's only 5 months old.I've seen the Marineland C-360 on sale for 120ish. That's what brought about this post. Thanks for the responses!
