So I have a Sicce Whale 500, the tubes are an odd size. They are a 15/16 mm but I can't seem to find an inline diffuser that has that size. Are there any options out there for me to use on my Sicce? Or do I have to stick to a ceramic in the tank diffuser.
if they are 15/16 mm ID just change the tubing to 16/22 should be a direct replacement and 20 foot of it is like 7 bucks at home depot, or you can buy it off Ebay cheap as well if the hose barb is 15 mm just use a hose clamp should seal fine.
