Hi,

My Juwel tank comes with a sponge filter impregnated with a resin which removes nitrate.

If I put this in the filter will the resulting zero level of nitrate effect the plants? I keep reading that nitrate is needed by plants.

I use Seachem Flourish and Excel, will these be removed by the nitrate removal sponge in the filter?

plants need nitrogen and that's in nitrate.

And are you sure about this magic sponge that removes nitrate?
i've never heard of such a thing. I guess it works like activated carbon... It'll absorb everything including nitrate. If you have a planted tank, you tend to stay away from such things because it'll take nutrients away from the plants.

most nitrate stuff don't remove all traces of nitrate just a bit of it.

The tank is a Juwel, they use coarse grade sponges which have been impregnated with a nitrate remval chemical.

I have taken it out and you can see the difference in just a few days..;0
