Water change schedule

[Partha007]

Between Water change schedule- 10% every 10 days versus 30% monthly, which one better for a fish-only tank?

As you can see 10% every 7 days will give a little bit better water in average than 30% every 30 days. I have also put in a daily WC of 1.4 % and 3 % as comparision.

How will the graph look like for 10% every ten days?
What schedule of water change(amount and interval) may be a balance for reduction of pollutants, efforts on the part of aquarists and no sudden big changes in water chemistry?

 

[Lasse]

In a only fish tank - the chemistry is not very critical but I think that a daily WC between 1 and 3 % would be the perfect balance of all three things you mentioned. It can be set up automatically. Answer to your question

How will the graph look like for 10% every ten days?
