Cyclic Tasks: Water Testing

This article is part of the “Cyclic tasks” series, intended for beginner aquarists who are looking for the basics of running a saltwater aquarium, or for those who are considering setting up a tank and want to understand the amount of work involved.

In order for the aquarium to function properly, we must regularly undertake certain works. If you’re a beginner aquarist, you’ve come to the right place!

Let’s now talk about a very important topic, which is monitoring water parameters. To gain the needed knowledge, I recommend reading the materials available on Reefpedia.

For starters, you will need knowledge about the basic parameters and their importance in a marine aquarium. You will find the key information in this article: The basic water parameters. Once you’ve got the basics down, it’s worth figuring out when to test each parameter. Each aquarium has different needs, so a plan tailored to your tank’s needs is a must.

I also recommend reading the article on how often we should test individual parameters: How often to test water parameters? The information contained in it will help you to set your own schedule.

In a tank with easy animals, manual testing will suffice, but with more advanced stock, such as acroporas, it will be necessary to do the measurements several times a day. Therefore, in this case, automatic measuring devices, such as KH keeper Plus, are very useful.


In marine aquaristics, it’s much better to prevent problems than to fight them, so it’s worth getting into the habit of testing water parameters regularly.

Thank you for your attention! I encourage you to read more articles. Gaining knowledge is the key to success in our hobby.

Reefkeeping has been my passion for over 10 years now. I love learning. The hobby has taught me many valuable lessons, patience being the best example. Combining work and passion is my path. I run Crazy Coral, a marine aquarium shop, for a number of years. Building this business from the scratch I learnt from my own mistakes at a heavy cost.
Later I managed a project aimed at development of methods for quick growth of Corals in non-natural conditions. The project was carried out by Get Sales, Poland. Presently, I am responsible for distribution strategy at Reef Factory, of which I am a co-founder. The company produces smart devices for marine aquaristics. The last projects I have been involved in are Social Reef and ReefPedia.
