    Lower the nitrate

    Does anyone have a great idea to lower the nitrates?
    Big waterchanges don't have any effect when the tap water have a nitrate level at 25 mg/l.
    The pond holds 50 mg/l.

    Any ideas??

    Not an expert but...

    I've read that a Trickle Tower in your set-up helps to degas and lower Nitrates Nitrate, NO3-N,

    I have one on my side 500 gallon tank and my levels are close to, if not at, nil

    Hejsan,

    I think most folks would indeed say try to keep nitrates below 40ppm. Very tough when the source water is 25ppm.

    Personally I use bakki house showers that help remove nitrogen compounds (ammonia, nitrite, nitrate) from the water and also drive up the dissolved oxygen levels.

    I'm guessing your tap water is from a well. If so you can get filters that remove the nitrates before going in. If your tap is from a treatment plant then your test kit may be giving a false read from the chemicals added.

    Where can I get those filters?
    Haven't seen them around here.

    I have used a homemade Bakkishower and I didn't think that it worked.
    I used it togheter with a Squaretop with Jap.Mat. Before the SQ Top.
    So I removed it.

    Nej,

    I have worked for LM Ericsson in Kista/Stockholm for 23+ years. I end up in Stockholm a couple of times per year.

    Stefan,

    I saw this over on another forum. I thought it was of interest for this thread.

    The chemistry and bacteria reaction of the trickle filter is difficult to explain it on this forum as they evolve around the H+(Hydrogen), O2(oxygen) and N(Nitrogren).

    In short, the large increase in the good bacteria together with its bacterial reaction and O2 *takes* away the nitrites during the conversion process(ie from NH3 to N02). The end resutlt is no or little nitrites is left for Nitrobacter reaction after going thro' the trickle resulting in no or little nitrates(which is the end product) leaving the filter system and back into the pond.

    I get them from a company that specializes in home and industrial filter systems. Send me a PM for the link. Not sure if they ship Internationally but you should be able to find someone in Sweden who handles them. Just google "nitrate filters".
