You need to empty half of the tank and replace it with fresh water. You need to leave half of the of water because if you put all new water in it becomes a shock for the fish and it could die.
- Empty half of the tank (with a cup for a small tank or a hose pipe for a large tank) you can pour the old water onto your grass but not down the sink.
- Refill the tank with the fresh water. If it's cold use a watering can, it can be time consuming depending on the size of your tank. Do the same with tropical fish but with hot or preferred water.
- Put the needed fluids in which take away chlorine that can damage the fins and then walla
- If you use a hose, put one end in the tank and the other in a bucket or watering can.
- Put the can/ bucket above the tank for flowige but if that isn't possible suck on the bucket end of the hose so the water goes down the hose whilst the can/ bucket is below the tank. (BE CAREFUL NOT TO INHALE OR SWALLOW THE TANK WATER)
- This way is way quicker than using a cup, trust me, I am not fooling you in to sucking up fish water :)
