Plant to absorb nitrates?

java moss or java fern will work great for tying to things.


what size tank, and what size/type of light? the WPG rule is way off most of the time.

Water wisteria should work, or anacharis. You want something that grows FAST.

I have Najas indica in multiple tanks growing under a variety of light levels. It even grows well enough in the 10 with just a standard fluorescent strip light. "Natural daylight" bulbs are usually 10,000k, plant bulbs are 6700k.

I had had all of the above... I vote for najas grass. That stuff will take over your tank.

Wisteria, hornwort, anacharis, guppy grass...I find the last two to be a pain in the butt though.

Java fern, moss, or anubias would work well given the environmental constraints but they're slow growers thus don't absorb NO3 well.

water sprite all the way, it can grow in low lighting and eats nitrates like no other

something effective or something in your tank actually?

for in the tank with no regards to what a pain removal will be once your tank is a green box... najas definitely!

to fill in a corner or back area while consuming nitrates... wisteria.

for best results in your tank... something either floating or breaking the surface to make use of co2 in the air... not only are your normal floaters good options but stem plants often do well as floaters too.

for best results... a hardy house plant that grows well, demands little and doesn't mind a bad case of "wet feet". pothos in an hob or sump filter would work very well imo.
