Water Conditioners that remove heavy metals
I have a bottle of Aquarium Solutions Ultimate water conditioner and it says it detoxifies Heavy Metals (including Copper). I also picked up a bottle of Flourish which states it has Copeer at 0.0001% in it among other type of metals.
Is it safe to use this type of water conditioner for a planeted tank setup, or and I removing some essential nutrients for my plants? Just thought I'd ask to make sure I'm using the right type of water conditioner in case it mattered.
