How to Clean Dosing Pump

[Super Fly]

I noticed my Bubble Magus doser was dispensing alk at higher rate than calc even though they were set to dispense equal amounts. After research, I learned that this was result of worn out dosing tube and that the BM dosing pump head should be taken apart and cleaned with dosing tubes replaced every 6 months (which I think is excessive and plan to do this annually).

Online some say to grease each part of the head assembly including tubes vs only grease the pins & ID of rollers that spin the pump head. Anyone know which is the correct method, i.e. avoid putting grease on the tubes? Thx

anyone? ...@ReefSquad?

Don't grease the tubes. Replace the tubes (or simply realign them in dosing head) quarterly. Its what I do, if you are already having issues, how long has it been since the tubes were replaced?

Great, thanks! that's what I was leaning towards. Had unit for few yrs and never replaced tubes, wasn't aware. Just bought 25' of tubing online and will replace them this weekend.
Again, thanks for reply
