Win an API Freshwater Master Test Kit!


As part of our Practical Fishkeeping Aquarist Diploma, this week, we’re giving away an API Freshwater Master Test Kit, to one lucky winner!

The API® FRESHWATER MASTER TEST KIT measures the four most important levels in freshwater aquariums quickly and accurately, including pH, high range pH, ammonia, nitrite, and nitrate.

With scientific accuracy for professional results, the reusable FRESHWATER MASTER TEST KIT comes with four glass test tubes with snap-tight caps and a convenient holding tub for easy storage. Also includes a step-by-step instruction booklet with a colour chart that provides information on how to correct unsafe water conditions.

Testing your aquarium water has never been so easy or accurate!

Plus, a bundle of API branded swag items will be thrown in too.

Take part in the PFK Aquarist Diploma

Each week, over a five-day period, we’ll be taking you through one basic but essential area of the hobby, covering water quality and chemistry, filtering and the nitrogen cycle, fish physiology and habitat, disease management, and aquarium husbandry and management in turn. We’ll post up a new part of each module daily from Monday to Friday, until all five modules are covered.

At the end of the five weeks, you’ll have the opportunity to take a test to see if you qualify for the Practical Fishkeeping Aquarist Diploma. By that point, you’ll have read through and had time to ingest all of the information from the models — there’ll even be a short ‘practice questionnaire’ to get to grips with before the proper test.


 This competition closes on Sunday July 5, 2020, and is for UK residents only. Good luck!
