How high does it sit out of the FIJI 20 sump how much clearance do I need
Question by: Karl Mayfield on Apr 25, 2023, 3:45 PM
I would say you need at least 6.5 inches of clearance. The is giving a small amount of wiggle room so you can change the fleece rolls a little easier.

Will this work with the Fiji 20 gal sump kit if I cut the right sized opening where the filter socks were?
Question by: Tyler Wandschneider on Apr 19, 2023, 10:41 AM
Yes, you just remove the screws holding in the media basket and slide in the ARF-20
