ecotech versa and neptune dos

[Cumboxgj]

i recently brought these for my aqauriums and i was wondering what fittings and tubing are reccomended for these dosing pumps
one of my versa I'm going to use as an auto top off and the rest with be for kalkwasser and all for reef. You're help would be greatly appreciated

Normally you are supposed to use a special tubing for the DOS (they provide some with the unit). However personally I use silicon 5mm everywhere and it works for me (I have both a Versa and DOS)

i think 1/4" tubing should work for both. but im sure their proprietary tubing is slightly larger.
