| Post subject: | Heavy feeder for nitrate |
I am using a small aquaponic system to reduce or eliminate nitrate. The aquaponic system is on top of the fish tank and I use a continuous drip system. I am currently using peace lilies, interesting, three very large peace lilies can't keep pace with 6 medium sized cichlids. After a water change, nitrate will drop down to close to 10ppm, but within a week or so, it will increase to 80-100ppm. Plants are health but obvious can't use up all the nitrate produced. Any suggestion on some other plants that use more nitrate? Considering that it is indoor with indirect sunlight. Thanks for helping. |

This was brought up a little while ago, I think the consensus was Mint. |

Mint is an easy one to grow under most conditions. So long as you don't mind it taking over the system. If there is more space to fit more plants in, lettuce might do ok with the lack of direct sun but it is a light feeder. Many green leafy house plants might do ok in your situation. |

My current houseplants (peace lilies) are doing well except they aren't using up enough nitrate produced by the fishes. I just went and gotten two common mint. Hopefully they will use more nitrate than the houseplants. |

I expect that any plant grown in low light conditions is likely to end up, in relative terms, using a fraction of the nitrate of a plant in proper light conditions. I put a small AP bed over my aquarium (in outdoor entertainment area) which received little direct sunlight. Plants like lettuce and toms did okay for a short while, but then went to pieces because of the lack of light. |
