I do a water change every fortnight, and just remove 30 litres is that enough for a 300 litre or should I remove more :snowman:

I tend to remove about 25-30% of the water from my tanks when I carry out a water change. Personally I would remove slightly more water when you carry out a water change, 60-70L should be plenty.

there's always one

If you only change about 10% each time, you might find that wastes accumulate more quickly then you are diluting them out.

I would recommend around 25% or so as Daran suggested to keep the water quality good. If/when the tank is fully stocked, weekly changes might be better.

Remember there's lots of info at The Tropical Tank main site!
