I changed from Clarisea Gen 2 to Gen 3 in end nov last year. Below is my review for Gen 3. If any reefer ask me if worth the change or not, my answer is yes! Below are the reason why. 1) I am a neat guy and I am sure to cable tie all cables. Even for my skimmer, I diy mod to a quick release at the skimmer end so I can easily remove to wash if needed. However, for the Clarisea motor, is it a DC cable and hence not so easy to mod and of course due to warranty issue. The Gen 3 come with a quick release near the Motor end and you can easily remove the motor. Very helpful when changing the filter roll. In The past, I need to do it at the slump area as my cable is tied and tend to make a small mess. 2) The ability to remove the filter roll with jus a push! I used the same tool to try and remove Gen 2 filter roll but unable to do so and hence I am doubtful for Gen 3. I jus changed the roll today and it was a breeze. So easy to remove now. Previously I will use a pen knife to cut and cut till I remove the roll. Conclusion! Gen 3 for the win! Sent from my iPhone using Tapatalk
