Red Sea ReefDose Tubes 4x3m 10' Blue+Green
Genuine replacement tubing for a ReefDose that's dripping, kinked or discoloured. This is the genuine Red Sea ReefDose tubing pack (part R35358) for the ReefDose 2 and ReefDose 4 dosing pumps — four 3 m lengths of colour-coded TPE tube in blue and green, cut to the 5 mm OD / 3 mm ID bore the ReefDose pump head is calibrated for.
Key features
- Genuine Red Sea part R35358 — correct bore for accurate ReefDose delivery; generic aquarium tubing will throw off a calibrated dose.
- Four 3 m (10') lengths, blue and green — enough tube to route two colour-coded dosing channels from pump to sump, even on a long cabinet run.
- Flexible TPE — kinks less than rigid tube over a tight bend behind a cabinet.
- Colour coding keeps supplement lines identifiable — no more guessing which line feeds which additive.
Will it fit my ReefDose?
Yes, on both current models. The ReefDose 2 and ReefDose 4 use the same tube spec, so this pack fits either pump.

Care and maintenance
Cut tubing runs as short as practical — less line volume means faster priming and more accurate small doses. Replace a length as soon as it kinks, clouds or develops a slow leak at a fitting; a compressed tube changes flow rate even if the pump's calibration hasn't.
Suitable for, and not suitable for
- Suitable as a genuine replacement for cracked, kinked or badly stained ReefDose tubing.
- Suitable for adding two extra colour-coded lines to an existing setup.
Not a substitute for the tips or the gear motor — this pack is tubing only.
Goes well with
- Red Sea ReefDose Tube Tip Set — fit new tips at the same time
- Red Sea ReefDose Tube Organizer Clips
- Red Sea ReefDose Tubes Red+Yellow — for a fully colour-coded four-part system

Common questions
Can I use generic airline tubing instead?
Not recommended. ReefDose doses by fixed pump revolutions against a known tube bore — a different internal diameter changes the volume per dose even at the same pump setting.
Does this fit a ReefDose 2?
Yes — the tube spec is identical across the range. On a ReefDose 2 you'll only need two of the four lengths, with two spare.
What if I need four different colours, not two?
Pair this pack with the Red+Yellow pack for four distinct dosing colours across the system.
