Why do water changes?

I admit, water changes have never been my thing. Partly because I'm a bit lazy, and partly because I just don't like it.

But unfortunately it is necessary to keep your aquarium water healthy

Both for your fish and your plants. Many professional aquascapers and aquarists swear by it too. Fortunately, I have now developed a method that allows you to do your refreshments quickly. That saves you a lot of hassle!

That's why water changes are important ...

As mentioned, many professional aquascapers (including Takashi Amano) swear by it: water changes are a must for a healthy tank! Here are a few reasons:

  1. Bad substances that often lead to algae (e.g. ammonium) are removed in time;
  2. Diseases and all kinds of ailments in fish are prevented;
  3. The tap water you refresh contains a lot of minerals;
  4. You also introduce a lot of oxygen into your aquarium, which is healthy for your fish.

So it comes down to removing all sorts of bad stuff from your tank and replacing it with all sorts of goodies for your fish and plants.

How often and how much do you need to refresh?

I recommend changing about 25 to 50% per week. After each water change, re-dose the large dose (30ml on 100 liters of aquarium water) or the small dose (10ml on 100 liters) of your bottle of All-in-One. You don’t feel like doing that many weekly changes?

I understand that 🙂

In that case you adjust your dosage according to the amount of water you change. Suppose you use the large dosage and you only want to change 10% per week instead of 25%, then you also dose only half of your bottle All-in-One, so 15ml on 100 liters of aquarium water. There will be more nutrients left over in the water because you’re doing less water changes, so you don’t need to add as much. I still advocate wat changes though, so that’s why I recommend at least a 25 to 50% weekly refreshment.

Change your water within 30 minutes

A while back, I wrote an entire article on AquascapingBlog that discusses how to change large amounts of water very quickly. If you want to know how I do it, read my article on AquascapingBlog. I now use this technique for all my tanks and it works well. Plus, the fish love it. Check out this (old) video:
