Water testing

Just received my water testing results from aquariumwatertesting.com . I have 2 components that rated high that I have no clue how to reduce. All of my level were as expected except silica and Molybdenum. Both were indicated as high. I know a source for silica is tap water but I am using a RO/DI system and my TDS are zero. So I really don't think that is the source. I am also being told it can come from the natural rock in the tank. I am using a GFO (Phonban) along with phosguard which it my understanding also absorbs Silica. So it unclear how to remove it. For Molybdenum it unclear if it bad based on other threads. In terms of other additive I use seachem iodine, Strontium, calcium and Kent Marine Magnesium. There seems to be lots of opinions what the level should be. Any other source of Molybdenum I might have over looked. The only other additions I use is Zoe and Zoecon and Garlic. I have look at the bottles and nothing indicates Molybdenum

Unless your having diatom issues, I wouldn't give any thought to silicate. As for Mo, it's a necessary element and again I wouldn't be concerned about it being high.
