Is there an issue with the effect of NaOH dosing on the tubing?

[Koty]

The pH of 1 or 2 M NaOH is very high. Does anybody has experience dosing it for a long period of time? I fear for the shortened life of the tubes. My pH is always 8.2.Hopfully moving to NaOH dosing will increase it to 8.4

What sort of tubing are you using? It is straightforward to look up tubing compatibility in tables.

Whatever tubes come with Reef Factory pumps and the Redsea colored ones.
For the Redsea ones, considering what NoPOx is made of, I would guess 1M NaOH would not be a problem.

Just an update: Reef Factory confirmed that dosing NaOH is fine

Glad that is OK.

As a general rule, some tubing is not OK, and some are OK. Tubing compatibility charts are generally available to look up sodium hydroxide solution compatibility.
