Understanding the nitrogen cycle and where it's at is essential for knowing when you can start adding live stock to your aquarium. Adding fish or shrimp too soon is fatal and has to be avoided at all cost.
We've put this set together so you can invest in 3 quality test kits and at the same time, make a saving. The 3 test kits are
Ammonia - extermely toxic and fatal to fish within 12/24 hours
Nitrite - toxic to fish and fatal if left untreated for 24/48 hours.
Nitrate - completely safe and used by plants as a food source.
Having these test kits in your cabinet is essential. You're looking after any livestock you have and as a result there's no need to make any mistakes. It's also improving your knowledge of water chemistry and from now on you'll know exactly when or when not to add fish or shrimp.
Each test kit has a QR code on the side which when scanned opens up a vdeo so you can watch exactly how to use it. Pretty cool!
