Do you still have the original tabs in the 1st chamber or do you have to remove them?I am going to be 100% honest. The instructions that come with the reef-n-roll REALLY are lack luster. The video on their website is less than helpful. BUT with all that being said I emailed the email address that was on the website and I mean within a minute or so I got an email from the owner and he literally walked me through step-by-step on assembly for my specific model and then I was having issues with the motor that reels the used filter up. He informed me that sometimes due to the tight tolerances they bind up so I just needed to use a little grip strength and get it to turn just a hair and well that did the job.
As far as the water level sensor yes there is one that is actually adjustable. I have attached some pictures that I just took.
Img_0181 - is the controller board. That thing is quite intuitive and if the unit detects an error it will sound an alarm.
Img_0180 - is a picture of the motor that spins and spools the nastiness that is filtered out.
Img_0179 - Is a picture of the level sensor. When the water comes into contact with that sensor it will roll according to the way you personalize it. I personally have it set to roll a small amount just enough so the water level goes down.
As far as setting it up. Heck if you’re having a tough time I am happy to help you set it up.
This is extremely helpful!
