Brightwell Aquatics Xport Dimpled Bricks Leaching...aluminum, tin, lithium?

Hi,

Looking for any info out there if these bricks or blocks leach anything into the tank? Aluminum, Tin, Lithium?

Did a recent ICP test and those were off the charts. See this thread below:

ICP Test Results, Help! High Tin, aluminum, lithium and silicon?!?!

Here's how I do it. I turn it on, flush with the TDS meter on, and I keep flushing until TDS reads 0. While flushing, my TDS will count down from like 80 to 0. There's a good chance you're putting TDS into your fresh water. I'm no metal expert, but it seems they could be coming from your...

I recently added 4 of the bricks to my tank about 3 weeks before I got this test. Not sure what else could be leaching? Someone mentioned glass leaching tin which I’ve never heard before? Some said maybe the dry “life rock” I used to start my tank?

Some pointed to the bio bricks/blocks so interested to hear what people say.

Thanks

Ive had one dimpled block running in my tank for 14 months now and done 3 Triton tests. Nothing elevated. Aluminum was on my first test but that was due to running phosguard which is aluminum based.
ive since added another plate.

When I used Marine Pure blocks I did have elevated aluminum but not tin or anything else. When I switched to Brightwell nothing was elevated. Not even aluminum.
