Hi all,
Up to you really, 10% a day should be enough, but you can;'t really change too much. I like routine small water changes. If you are adding fertilisers (using EI or similar) it is still worth doing a big change or if you have a very heavy fish load.

I'm changing 20% a day at the moment (with cooler water each morning) as the tank temperature is climbing into the 80's (Fahrenheit) each day.

cheers Darrel

I would think the 10% per day plus a larger 20-30% once a week (presumable includes filter wash or gravel clean etc) sounds just fine to me.
