Recently got my water tested at Triton Labs
would recommend it, well worth the €30 and results very beneficial, if only to confirm they match my test results.

However, one negative found in my water was presence of lead pb.
1.67 μg/l
I cannot find the source of the lead, its not from the water changes as only using LFS water and that tests ok.

Only other variable I had the week I took the sample was the use of cement (Aquascape Construction Epoxy) to fix some corals.
No lead in that I think and Google not much help either.

Anyone care to guess the source of the lead?

No metal fixtures anywhere in the system? Ive seen them cause such issues on ro systems in the past! (That was from LFS source aswell)

I had led in my first tank and I found out the hard way when shrimp start diyin, it was caused by a dodgy magnet glass cleaner
And the propeller bar in all pumps ect. Need to keep an eye on them

Thanks Jeff, I now suspect the magnet glass cleaner too. I left mine constantly in the tank. I have taken out now for last 3 weeks so will send off for another test shortly and see if the lead is gone.

Pollyfilter will remove it in a few hours
And you can then put some led free water from tank in a bowl with glass cleaner and a small piece of clean pollyfilter and just stir it around now and again for a few hrs and see if it go's the same colour as the one from the tank then you'll know if its that
