At first glance I'm pretty happy with the design compared to previous models. Getting it hooked up now because I'm extremely curious.

Cool. Didn't know they made a newer version. Do you know if it is just merely cosmetic changes? Or did they make some tweaks that improved any sort of functioning (stronger water pump, better "zero" water-bypass, easier priming, thicker plastic material, or anything like that?)?

So far the flow seems similar to the older 3 series and it's nice they put the pump back inside the filter where it belongs. The filter housing seems to be more bulky and durable. The baskets inside are the same as the old one but the overall housing is much bigger. I filled the entire canister up with water before sealing it and priming was maybe ten pumps at best and good to go. Honestly it seems like they took all their best ideas from previous models and incorporated them into an overall nicer unit.

Not to mention at $57.99 shipped it's a steal. I'm partial to eheim quality and they've always been my favorite but for the price these Sun Sun filters have done their job well. Only thing I've noticed is their tank size ratings are terrible. For example a 403b I have is a the perfect size for a 38 gallon planted tank not the 100 gallon they claim.
