Hey all! We recently sent out ICP tests for two of our systems that weren't doing great and this is what the results looked like. Most of the "issues" are quick little trace element fixes but the main concern I'm having is the aluminum through the roof! I'm fairly sure its coming from the media blocks in use in those systems. How can I remove aluminum? Additionally, the chrome on one of the systems is very high. Where can chrome come into play here? I'm not sure how it got in the tank.
