Not sure if some dosing pumps cannot take an RODI line but mine can.

I'll check just never made the mental comparisons in size.

You can stretch a small section of soft dosing tube over a 1/4” RO tube. I’ve done it before for different reasons. Yes you still have a small section of soft tubing, but better than the whole length if you believe it’s a source of contamination.

Here is a pic of my setup.

For what it's worth, I've never had tin show up on my ICP and I'm using Red Sea brand dosing line.

I'd put a cable tie on there just in case. If you don't have a good seal or could affect how accurate your dosing is (an issue I had until I got it super tight).

I just re-watched a presentation from Dr. Christoph Denk / Oceamo (in German), and he confirmed that they found rather high amounts of tin in some tubing products in their tests.

They apparantly offer tests for tubing samples at relatively small amounts 12 USD, but I could not find this on their website. Still, it confirms that this is apparantly quite a common issue.

I just grabbed the cheapest Amazon made in China one I saw figuring it was just a tube. If I suspected this was a possible issue I would have spent a few more bucks.

Good idea!

Used to come from cheap glass in aquarium manufacturing too
