All,
But who has the time to put aside for changing water daily?
Changing daily, and assuming an equal or greater overall volume to be changed; the water will stay as close to the source, but there will be less swings in water parameters, including temperature, or hardness, or pH if so inclined.
And assuming you are not changing water with aged water, there are dissolved gasses that will gas off from the aquarium water, that adding in a large volume will cause, say CO2, to rise in the water..
swings like this will have bigger effects on things like algae, and more sensitive animals including fry or shrimp
Doug, I understand those aspects and benefits of it, but it's the 25%/day that I'm hung up on. It's not going to fit all applications. I know we don't change water ONLY for nitrate reduction, but if you had a daily nitrate creep of 2ppm, you're only dropping it by 0.5ppm/day by changing 25% of the water. Nitrate creep is eventually going to ramp up above where most want to keep it.
Nitrate creep is going to happen however you change your water. which is why I always suggest that nitrate readings should determine the size and frequency of water changes.
ideally stocking should have a good bioload so the nitrates (and such) created should be reflected in the size and frequency of the water changes taking place.
I'm too busy working to deal with any scary math... and too brain-dead to understand any of it anyways, but nitrates may creep up higher and more quickly, but there is more at stake than just the level of nitrates.
