small filter pad


the filter pads are size b, which are smaller the the old 350, which took a size c. to me. the 350 pad will hold more dirt. when you have african cichlids, its a big deal very disappointed. otherwish, quieter. dum move on marinelands part

Best filter


Best filter I've ever had! Very quiet, hinged lid is a huge improvement but the in tank pump is the biggest and best improvement! Very happy with this filter.

I'll stick with The Emperor 400


Been using Emperor 400's for years Not happy with this new product, Intake falls off if you tap on the tank, Also not easy to take advantage of using extra Carbon like the Emp 400. Filter cartridges do not fit tight.
However they are very quiet
