Product description

Size Name:250ml

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.

    I am really pleased with Tetra Nitrateminus Liquid. When used regularly, it works and keeps nitrate levels low. Thus prohibiting algae growth and keeping the aquarium water healthy.

    Not sure about this product. No effect on my 120 litre marine tank nitrate levels after 2 months which are still around the 40ppm most of the time and go to 20ppm after a water change. Lost some pulsing xenia coral which I'm putting down to this but it may be a coincidence. I would not buy this product again and would instead go with macro algaes, turf scrubber or a fluidized reactor type product. The skimmer also needs to be turned off when dosing this product as it goes crazy.

    Excellent product. My tap water sits at 40ppm so I was struggling to get nitrate down as they was going of the scale when testing, after 3 weeks use my tank never goes above 10ppm.

    I had been struggling to get my nitrate down to 0 ppm for months and finally gave in and bought this after reading the reviews. To my surprise when I tested my water 2 days after using NitrateMinus my nitrate reading was 0 ppm! After water changes every 2 days, cleaning the tank, adding live plants and live bacteria this product was a life saver for my fish!

    Not sure if this works really. Purchased a Pozzani nitrate filter instead.

    Has taken the nitrates down slightly and seems to have helped my fish, it's a pretty small bottle though
