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

I bought these to provide a snug fit for an EV charging cable running through my garage wall. They worked perfectly to keep out drafts and crawly things. Highly recommended.

Worth the money!

This kit is great. I bought this because I know that the seller paired the cutting tool to be the perfect size and it was! Not just that, but the hole cutter was well done and cut thru the 3 layers - laminate, plywood and particle board with ease. The only thing that I would do different, is go to 3" next time. 2" was very tight when running the 2 @ 120 volt cord ends through the cap.
