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.

    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.

    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!

    I had Nitrate issues in the first two weeks of having a tank, this helped me in drastically reducing the levels to a safe point. Fish are strong and healthy.

    This has most definitely reduced the nitrate in my Juwel Rio 300. Like many others, I have nitrates in the tap water at circa 40ppm and it is a complete pain to keep levels low.

    I am not necessarily concerned about nitrate levels from the perspective of fish health, fish can comfortably thrive in relatively high levels of nitrate as long as ammonia and nitrite are zero, the issue is algae growth covering my live plants.

    Does what it says on the bottle, our water supply suffers with High nitrate levels, this is bringing it down and controlling it

    **UPDATE**
    Down from 40ppm to 20ppm pre water change - I'm just about to start my second bottle - it's working

    I've been using this for 6 weeks now and the readings seem to be considerably down. Having read more about this approach, it appears that Nitrateminus contains bacteria - which usually live in stagnant water.... so if my theory is correct then most of these die of when introduced to my "clean" fishtank but some are getting to live on and build up in the sub strata.... If this is the case then - when the little critters are established - I should only need to add a maintenance dose every now and again.... Will update with results.

    It does seem to reduce the nitrates - but not very much..... On price performance it's just dreadful... I was expecting to just have to use it on peaks but like so many of these chemical fixes... they require constant use. Next stop nitrazorb

    Item Sold by Pet World without English instructions for use!!
    After typing in the polish instructions into google translate I got the following instructions: Shake well before use. Pour 2.5ml for every 10 liters of aquarium water once a week. The activation process can take several weeks Organic pollutants in the aquarium lead to a permanent increase in the level of nitrates. Regular use allows to achieve and maintain low levels of nitrate (<50 mg / l) Recommendations: aerate the aquarium all night.

    I hope this is right as I don't have time to return it as I need to sort the nitrate levels out asap (we've had some new fish who seem to be having a baby boom) & the product take a few weeks to work anyway. I aim to return with an update on the actual product once I've used it for a few weeks.
