Water Changes On Small Tanks

[ghent_3rd]

I have tanks that are 18x10x10 and appreciate that I need to be careful with any water changes. I am thinking that when I have them stocked how it would be to change 1 litre of water every morning??

I can only assume that this would be ideal as it would give me a 25% water change every 6-7 days. Anybody already do this and is it a good way to change the water?

I see no problem in doing that, you could do 2 litres a day and still be fine providing your water is of a similar temperature and dechlorinated. I am currently doing 50% daily water changes on my fry tank and they're growing fast.

Why not just change 25% every 7 days instead?

To keep water change shock to an absolute minimum. You wouldn't change 100% of water every 4 weeks, you do 25% every week. It is actually easier for me to change smaller amounts due to how the tanks are situated and I could do it in about 5 minutes every morning I think. There are 4 tanks that I have to do so this just suits me better.

Yeah but you're not changing 100% every 4 weeks by doing 25% weekly, there are people including myself that have done 50% WC's weekly, as long as your tap water and tank water are of similar water chemistry you shouldn't run into any problems.
