Tin in dosing pump hose !

[Moggel]

Hello everyone,

I use the Chihiros dosing pump with the Chihiros tanks and Chihiros hoses in my reef tank. I have noticed that the tin value in the ICP laboratory analysis has risen since using these products. So I took the hoses, put them in osmosis water for 7 days and started another analysis. The tin value rose to 60 micrograms per litre within a week. The problem is that corals get real problems or die from 10 micrograms and more. Unfortunately I have also lost a few corals as I could not immediately determine the cause of this problem. I will probably be stuck with the damage.

Has anyone had similar experiences?


Kind regards

Moggel

Here's a picture of the hose. It corresponds to this product on your website https://www.chihirosaquaticstudio.com/products/dosing-tube-holder-x-for-chihiros-dosing-pump-only

For information, I also cut off a piece of hose from the hoses in the dosing containers and put it in osmosis water. However, I only cut off half a centimetre. But I think that the hoses I sent in the picture are responsible. I bought the hoses at Kölle Zoo, Ulm, Germany.

Thank you for the friendly and fast support. I have sent you my address details in a private message. Have the silicone tubes been tested? To be honest, I don't want to carry out animal testing at my own expense.
