A 600-word essay on cleaning a fish tank, Part 1. I have a large fish tank at home. Various tropical fish swim freely in it, adding a beautiful scenery to the living room.

Many neighbors, relatives and friends who come to my house will stop here to watch and admire it.

But recently, my parents have been busy at work and have no time to take care of it. The surface of the fish tank has been covered with moss, and the pure white sand is mixed with fish feces. The fish seem to be dissatisfied with the changes in the environment.

Yes, I swam very weakly.

So the idea of ??cleaning the fish tank came into my mind.

Just do it.

I first used a fishing net to transfer all the fish to the pool, then carefully took out the aeration rods and heating rods in the fish tank, and then brought a large basin and a thick pipe from the kitchen.

I put one end of the pipe in the fish tank and the other end in the big basin. At this time, the water flowed from the pipe into the basin... After the water in the fish tank was drained, I used a big iron spoon to pour a big spoonful of sand.

Ladle large spoonfuls into a large basin.

After half an hour of hard fighting, a fish tank full of sand was finally moved.

Then I wiped the fish tank with a cleaning ball, and I kept busy with my hands while humming "Hee Swish" by the Huaer Band.

Look at me wiping left, wiping right, wiping up, wiping down... I'm very busy!

Green moss fell from the wall of the fish tank due to my efforts.

Then I rinsed it with clean water a few more times, and the fish tank immediately looked brand new.

Finally it’s time to wash the sand.

With the help of my cousin, I moved a basin full of sand to the well platform of my grandma’s house.

I first put some washing powder in the basin, and then put in clean water. When the water was almost full, the sister and brother worked together to rub the sand, grab a handful, and rub it. The fine sand became soft between the fingers.

Be gentle and soften.

An hour later, all the sand was cleaned up by my sister and me, and it was snow-white.

When we poured the sand into the fish tank and then injected clean tap water, the fish tank immediately changed its appearance.

Look, the tropical fish have started their happy journey of freedom again in a clean environment.

When my parents came back from get off work and saw the changes in the fish tank, they smiled happily and praised their children for growing up and becoming more sensible!

Listening to their appreciation, my heart felt sweet.

600-word essay on cleaning the fish tank Part 2 Today, the weather is not hot, and the water in the fish tank has not been changed for a week. The water in the fish tank has become very turbid. If the water is not changed, fungi and viruses will be produced in the fish tank, which will eventually lead to the outbreak of brown algae and snails.

If the tank explodes, they are the nemesis of fish and master fish killers.

To change the water, you must first unplug the water pump, then clean the fish tank with a sponge, and finally replace the fish tank with fresh water. It will take about an hour.

This is not an easy task. In order for my father not to have to work too hard, I offered to help him.

Dad unplugged the water pump and connected the drainage pipe. We were about to start draining the water. I saw a lot of fish feces and snail eggs coming out of the pipe. It was dirty and smelly.

I saw that the water in the fish tank was getting less and less, and finally the water was only one-third of the fish tank.

At this time, we need to flush the filter tube of the fish tank, that is, flush all the fish feces and snails below into the fish tank. This can avoid the lack of oxygen in the fish tank caused by the blocked filter.

The only bad thing is that the fish tank will become dirty at this time and it will not be ornamental enough.

But these dirty things will eventually be eaten by the scavengers and dace fry. After half a day, the fish tank becomes clear again.

Next, I started to add water. I turned on the faucet, and a small fountain emerged on the surface of the fish tank. It was as spectacular as Baotu Spring.

After two minutes, the small fountain disappeared, and small bubbles began to appear in the water, filling the water bit by bit.

At this time, the ecological filter box under the fish tank began to flow, indicating that we had added enough water. I quickly turned off the water and reconnected the water pump.

After changing the water, we also need to change the filter sponge.

Dad took out the dirty and black old sponge and threw it away. I helped throw it into the trash can and put the new white sponge into the filter box.

Finally, we need to add special coarse salt for the fish tank to prevent the fish from getting sick. I saw my father starting to put salt into the biochemical filter tank, and a lot of salt fell into it, as if it was snowing.

After an hour of hard work, the fish tank became very clean, and my beloved fish started to move happily again.

Although I am tired, I feel happy.

We walked around the market at a brisk pace for a while and came to a fish shop with an exquisite layout.
