It does make the water more clear, but it does so by removing elements out of the water. Unfortunately, it also removes ferts in the water that the plants use to grow. That's why it is not good. A better water clearing filter media would be purigen, which does the same job (probably better) and doesn't remove the ferts we add to our planted tanks.

purigen is an awesome product.
you can bleach it when its "used up" and use it again.
(after soaking it in dechlorinator of course)

my thoughts about this i went and read the link and notices that it took nitrates, nitrite, and amonia to. Aren't these also very important for plant growth to, it might not be taking out trace minerals but it is taking out the nitrates, nitirtes, and ammonia. what do you guys think about this?

so what should you use if carbon is not good for a planted tank and this other stuff takes out all of the nitrogen

so...wait are you saying purigen is bad for a planted tank...? I HIGHLY doubt that it can take out all of the "nitrates nitrites and ammonia" from the water...It prevents these from getting to a dangerous level for fish, yes...removes them outright...No. I may be new...but i really dont think plants need a deadly amount of the "bad" chemicals in the water...

If you really dont want to use purigen or carbon, just do your water changes.

but if you're dosing with ferts, you're wasting it to that stuff.

using purigen in a planted tank is fine...you should have enough nitrates in the water column that the purigen won't affect anything negatively. There was recently a poll done on whether purigen was appropriate for planted tank use; i think the results were something like 95 percent in agreement that purigen posed no detrimental risks to fish/plant health.

even if it were counteracting your dosing, it would also be ensuring that it didnt get out of hand...kind of a safety net...lol
