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 now have all of the essentials, but only through trial and error and sadly, a few dead fish.
If you’re going to keep fish in a tank you need to understand that fish poop, and fish food and poop rot. When they rot, they give off ammonium. Ammonium is poisonous. When enough ‘good’ bacteria develop, they turn this into nitrate and nitrite (also toxic, but slightly less so). This can be managed by further bacterial development, but also through regular water changes and chemical intervention.
This product contains a biological component which helps in the denitrification process. It’s a gritty product, suspended in a milky gel. I shalln’t put here quite what it looks like, but you can imagine!
As for the nitrates/nitrites, this isn’t an overnight fix, but in addition to other products I have bought, it seems to be doing the right thing.
I happily paid full price for this product, and believe it represents excellent value when compared to the cost of much smaller bottles from the shops. It is also dirt cheap compared to re-stocking your tank if your fish all die off.
Like I say, I’m a beginner, but if I can help with any questions, please leave them in the comments, and/or use the voting buttons. Thanks for reading.
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
Used in a 240 litre tank and didn't see much in the way of results, I'm sure it's doing something but I upped the dose and still couldn't really see much difference.
I'm going to start doing a water change in a week or so to see if that lowers the NO, but sadly the Tetra liquid seems to have a limited impact..
Sure it may work for others, but I can't recommend.

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.Published 1 month ago by Pen Name
