You could use some Poly filter to filter out the metals. I was running Triton AL99 and its an AI based phosphate remover, needless to say my AI was off the charts high. I used the Polyfilter and cleaned it up pretty good. Thats what i didnt like as well. I do use the Trition ICP just to sure up what i think im doing right make sure things are seriously out of wack lol... But these should be taken with a grain of salt, and not be the bible of water chemistry for our tanks. once i pounded that into my thick head things got a little easier trying not to chase numbers, if the tank looks good, then great!
