Nutrient Tubing for Bluelab PeriPod L3 - 4 m

Fresh Nutrient Dosing Lines for PeriPod L3 Systems, 4 m

Nutrient dosing lines age and can harbor algae, and a cracked or blocked line throws off every dose that follows. This replacement nutrient (LDPE) tubing is made for the Bluelab PeriPod L3, so it fits the pump and fittings as designed. It is supplied in a 4 metre length.

Commercial PeriPod L3 users dosing several nutrient parts benefit from keeping spare lines to swap during routine maintenance.

Frequently Asked Questions

Why is nutrient tubing separate from acid tubing?

Nutrient tubing is food-grade LDPE suited to nutrient stock solutions, while pH adjusters need chemical-resistant PTFE. Using the correct tubing on each pump line keeps dosing reliable.

What chemical concentrations can it handle?

As a guide, Bluelab lists maximum concentrations for this LDPE tubing of nitric acid under 10%, phosphoric acid under 40%, sulfuric acid under 50% and citric acid under 10%; potassium hydroxide, carbonate and silicate can be used concentrated. Bluelab notes that temperature, pressure and UV exposure can cause tubing failure, so test the tubing with your chemical in your application before relying on it.

How often should I replace dosing tubing?

Replace tubing when it shows cracking, hardening, discoloration or leaks, or if doses become inconsistent. Bluelab warrants PeriPod cassettes and tubing for 6 months, reflecting that they are wear parts.

Is the tubing cut to length?

It is supplied in a 4 metre length. Fittings are included, as listed above.
