Tetra NitrateMinus reduces the algae nutrient nitrate (NO3-) reliably and in a natural way. 

  • Reduce nitrate levels
  • Prevent algae
  • Stabilise water values

The contained particles promote the activeness of microorganisms, which feed on nitrate and break it down biologically


For better water quality


 

250 ml for 1,000 litres of aquarium water


For all freshwater and marine aquariums

High nitrate levels can encourage excessive algae growth, which can make the aquarium look unsightly. Unlike other nitrate reducing products, which need regular recharging and replacing, Tetra 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 Works:

NitrateMinus utilises a natural biological process called de-nitrification 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 Use:

Simply add 2.5ml/10 litres 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 under-gravel filters

Nice Case & Keyboard
Color: Blue
Love this case with a keyboard. I like using the keyboard vs using one on the screen of iPad. And the keyboard has rechargeable batteries instead of having to buy batteries. And it protects my iPad.

Beautiful, and everything I want it except that the keyboard keys didn’t work😭
Color: Light Pink
I searched and search for the right keyboard case for me. The most important thing for me was to be able to remove the iPad case itself from the whole case and keyboard, and this one was it. Unfortunately, when I started checking the keyboard a lot of The keys were not output in the correct symbol or letters. So defeats the whole purpose of having a keyboard. I returned it and asked for a replacement, thinking that the item was defected, but when I got the New replacement, it was the same thing so I tried to contact the seller, but there was no option to do that. Therefore, I had to return the second replacement keyboard and look for another keyboard cover.

Quality and Functional
Color: Navy Blue, Color: Navy Blue
I was looking for a case that could rotate and includes a keyboard. I have the gen 5 Ipad Air and it fits just fine. The part that rotates is magnetic (pretty strong) so if i just want the part with the ipad, I can just take it off. Keyboard is magnetic and the touchpad is such a bonus. It was easy to connect and every key works (can also change light color). Im also really impressed with the quality of the case, its pretty thick and even the plastic is nice. The navy blue color is also super cute, wish they had a dark red color too.

ABSOLUTELY PERFECT - I LOVE THIS!!!
Color: Pink
I absolutely LOVE this case and the keyboard - it’s absolutely perfect in just about every way. If I had to get nit-picky and find something to give feedback on, I would say it is a bit heavy and it is a bit annoying that you have to move the keyboard forward when you want to use it and backward when you want to close up the case but I don’t care, I love it!
