Product Description

Box Contains

  • Each order comes with 1 x Tetra Nitrateminus Liquid, 250 ml
  • Product Description

    High nitrate levels can encourage excessive algal growth which can make the aquarium look unsightly. Unlike other nitrate reducing products which need regular recharging and replacing NitrateMinus is simply added weekly to the aquarium. Also unlike many ordinary nitrate reducing products NitrateMinus does not need to be added to a filter system to work but is simply added straight to the water.

    How it WorksNitrateMinus utilises a natural biological process called denitrification to remove nitrate. Under conditions of low oxygen such as are found under the gravel in most aquariums special bacteria use nitrate instead of oxygen to break down the NitrateMinus granules. By doing so they steadily reduce existing nitrate levels and maintain a permanently low level. In addition to removing nitrates NitrateMinus also releases a low level of carbonates into the water which helps to stabilise the pH of the water.

    How to UseSimply add the required dose of NitrateMinus to the aquarium once a week to keep nitrate levels low. NitrateMinus must be in an oxygen poor environment to work. The effectiveness of NitrateMinus may therefore be reduced in aquariums with undergravel filters.

    5.0 out of 5 stars Easy to use, inexpensive & works! 30 July 2011
    Size Name:100ml
    We bought this when our fish tank had an algae problem, we have so far only used it once but there is already a very noticeable difference in the algae levels in our tank. The cap makes the solution easy to measure out & it is a very simple product to use, as all of the Tetra range is. If, like the reviewer below, your instructions are in German, shake well before use & the doseage is 2.5ml per 10l of aquarium water to be administered once weekly, it says it may take a few treatments for a noticeable difference but ours took only 1, you are also to keep dosing every week if you want to keep the nitrate levels down. Would definitely recommend this for anyone with algae-related problems!

    Just put the correct dosage into my 30l tank this afternoon and already I can see a difference.

    Tetra products have not let me down yet and do exactly as they say they will.

    5.0 out of 5 stars It Works 22 Mar 2013
    By oscar wilde TOP 1000 REVIEWER
    Size Name:250ml|Verified Purchase
    I have recently started using this product in a new tank, I have been using it for about a month now and the tank is very clear and the fish are all very happy. I guess with a new tank I won't see any visable changes as the set up is quite new, so I guess its doing its job. I would recommend this to anyone.

    5.0 out of 5 stars Very good product 22 April 2014
    By Big Daz
    Size Name:250ml|Verified Purchase
    This product came 1 day after ordering and was very well packaged as per usual for many/most items bought from Amazon.

    The product it's self is in those handy sized bottles that 'Tetra' put the majority of there products in. The dosing cap is a great idea. . .Though to small for larger aquariums.
    I thought i would give this product a try, as i have a constant battle with high quantities of algae from the water in my area being so hard & alkaline.. Around 8-6-9 on the Ph scale. and have never had any problems with 'Tetra' products in the past..

    I placed the required amount in my main 340l display tank this morning. But with displacement from rock is holding around about 240l.
    The product looks a little like something else in water... hahahahaha, but in a short space of time, 2-5 minutes, disperses through the tank in flakes/clumps and the particulates sinks to the bottom of the tank. With having live coral sand (white) the 'Nitrate-Minus' can not be seen. . I am sure you would see it if you have a darker aggregate.

    Doing this dose, once a week as directed on the bottle i know will help control the 'Nitrate' levels, which with in the hour of being placed in my tank, has reduced the Nitrate count from 4.2 to 0.6. So in conjunction with regular water changes...(which is a must) regardless of any treatments you may use, i KNOW will reduce the algae problems on the glass.

    The fish had no interest in the product as it dispersed through the tank, and certainly do not appear to be effected by this.. but all in all, so far i am very happy with the 'Nitrate Minus', and would tell anyone who has high levels of nitrate...(far more than i have) to give it a try... I would imagine that if i test the water tonight, my nitrate levels would be zero..
