So a new Aquaclear 110 in the house. Got it set up last night and it really looks identical in so many ways that I would say its really not worth 'upgrading' from an older unit. My understanding is that the he new lid was supposed to help with the rattle problems. I will see how that one goes but it interchanged onto the older body just fine, in fact pretty much all the parts were interchangeable.
I did like the redesigned intake tubes. The bottom is so much better in design and the extension tube is a real extension not just two intakes stacked together. The strainer portion feels strong, not like its going to break like the older design. I did not use the prefilter sponge .
The redesigned U-tube seemed quieter when in was starting up for the first time. I guess its supposed to help with the priming. It will be easier to clean, that's for sure, since the sharp corners inside are gone.
I definitely would like to see the new replacement strainers come out soon because that I would replace on all my old Aquaclears. But otherwise its the same old filter with just a few minor tweak's
