I don't have high confidence in this company, and they fact that they quote their chloride result to a degree of precision that would certainly win a nobel prize if true (21156.196 ppm) demonstrates their lack of scientific rigor.
The only thing that seems concerning to me is the aluminum, which if accurate, is pretty high, but perhaps not high enough to be an issue. My testing showed issues at 500 ppb, but not at 50 ppb.
Are you using any sort of white media that might be aluminum-based?
Below are links to the media I'm using in my Fluval Flex 32 gallon. I'm upgrading to a 7-stage RO/DI system. I don't trust my tap water whatsoever
I'm also in the process of setting up an automatic water change setup using the Trident. With the new RODI and a continual, gradual, water change to better water, I'm very excited to see the eventual results.
In this article I will give some details of aluminum in natural seawater, and will discuss the sparse literature on the toxicity of aluminum ions to marine organisms.
