Regular 25% Water Changes

People like to keep aquariums, but no one wants to dip their hands in the water. At the most, they might install a filter and leave everything to it. If you have the bacteria culture along with the test kits then its fine, as long as you check it on a regular basis. Ammonia spikes can happen real fast and cause damage to your fish's internal organs. This is the one thing that happens almost everywhere, as most people do not understand the importance of maintenance.

Just like us, fish will urinate and excrete wastes. In the wild, this thing is fine as all of that is washed away by the current and the volume of water is too large to lead to a chemical buildup. But in your aquarium, think of it as your fish swimming in his own piss and shit soup. You wouldn't like that, would you?

As a fish keeper, I have come to an observation, that by doing small amounts of water changes on a regular basis, is much better than doing massive changes less frequently. This practise leads to a more gradual chemical change and temperature than the latter and your fish are not stressed by it.

Now before you do a water change to your aquarium, you need to observe the amount of fish and the amount of food that goes in daily. So lets say you have a medium size tank that's the size of your desk or maybe smaller, you have 5 - 10 goldfish in there, you feed them a tablespoon full of pellets once a day, then all you need to do is 25% water change on a regular basics. A power filter would definitely help too.

I speak from experience. At first I used to do infrequent water changes and noticed that my fish were sloppy, lethargic and didn't eat proper. But when I started regular water changes, they were healthy, active and hungry, at all times. So, to keep things simple, don't over stock your tank, don't overfeed, do your regular 25% water changes and run a filter continuously.
