Does Continuum phos w leach aluminium

[starrynight99]

I used phosguard to remove silica and phosphate in my system due to a hair algae issue. Recent ICP showed elevated aluminium.

I have now bought continuum phos w which is another white bead media. Does anyone know if it had aluminium in it? I couldn’t find the info in the internet. Thanks!

Do you have any bio media in your sump? That's a common aluminum leecher in the long term
