Maintenance Free Tank (Photo)

My question is: How to minimise water change ??? What is the minimal water change one can get away with without killing fishes?

At the moment, I have a 60L tank with 8 endler guppies, 6 corydoras habrosus, 5 rasbora brigittae, 5 yamato shrimps, 7 cherry shrimps, heavily planted. Add plant fertiliser three times a week. I do a 30% water change weekly for the past 5 months since setup.

I am wondering if I could get away with less water change? Perhaps once a month?

Would keeping less fish/inverts and plants mean less water change?

I know this is true for fish, ie one fish in a 60L tank would require less water change than 10 fish in the same tank. What about plants? is this equation applies to plants too? Less plants = less water change?

Any comments welcome!!

Non CO2 methods easily go 6-12 months without any water changes and those are only done to remove detritus and mulm build up after pruning.

Rather than water changes for export, you trim the weeds for the nutrient export.

You can add less light, say 1.5 to 2w/gal (at most), this will reduce the need for water changes and CO2 also.

Some of the plants will not do so well, but most of them will in your set up.
You will need to add water for evaporation.
You can check my site on the free side for the non CO2 methods, it will give you more info.

You should add that it isnt free or at least not all of it. I registered at your site to try to get some information but alas, most of the threads you must subscribe first, which is for a fee.

Hi Tom,

Thanks for the advice. I will take a look at your website.

Another question, if it was a low light CO2 injected plant-only tank, can one do without water change at all? Just top up water and add fertiliser once in a while?

It's an indian almond leaf i beleive. It's meant to drop the KH a bit I think.
Adds tannins for shrimp tanks. Others argue using them for other domestic leaves, oak, NA almond...

Yes, it is an indian almond leaf which I put in for both decoration and to induce shrimp breeding!

More photos of the leaves here if interested:

If it's plants only sure but you have some great snails that would like some fresh once in a while. I've had nitrate swings hurt shrimp and probably not helping the snails. It's just best for all to keep up on the changes and at minimum 2 WC per month for a mid light CO2 tank. The issue with no change is keeping up on other things like Ca and MG. Over time what little is used will be depleated. I'm sure Tom has some nifty way to keep these in check over a long period of time with no CO2 but it's good to understand what is happening regardless of the rate of uptake.

I think you first have to look at the reasons for doing water changes.

To keep the water clean:

to prevent toxic levels of nitrite or ammonia

to prevent high levels of DOC (dissolved organic compounds)

To keep oxygen levels high

to prevent high levels of excess nutrients from fertilizers, DOC, fish waste

to raise levels of certain minerals that may be in your tap water.


By testing ammonia and nitrite levels you can see if a water change is warranted for that reason

A smaller fish population, and removing dead or decaying plant leaves quickly, and cutting down on fish feeding will help keep DOC low.

Adding an air stone will help keep oxygen up, as well as good water circulation

Providing nutrition to plants via the substrate without adding anything to the water will prevent excess nutrients in the water, as well as worrying about what might be lacking in the water. This is the key to a total low tech approach as outlined by Diana Walstad in her book The Ecology of the Planted Aquarium
