Beginner: Clean a Goldfish Bowl
Clean a goldfish bowl
If you choose to use a goldfish bowl over an aquarium tank or outdoor pond, you will have to change the water almost daily because all goldfish in general produce a lot of waste and ammonia (see more about this topic at Nitrogen Cycle). By adding a layer of small gravel and a few living plants will help keep the water clean longer. If you decide to add an algae eater, you will need to give him space too and you will need to keep the water around 77F/25C. This might require you to buy a heater if your water temperature is to cold (see why this is not recommended at Goldfish and Algae Eaters).
To clean the water take out 50% of the goldfish bowl’s water and replace it with clean water none chlorinated water. If you are careful and don’t take a long time to do the water change, you can probably leave the goldfish in the goldfish bowl you are cleaning (see more about why at Goldfish Diseases and Goldfish Water). During this time you can scrub off any algae with a clean rag with no chemicals or detergents in it. We recommend an algae scrubber that you can get from your local pet store. But remember, a little bit of algae is a good thing (see more about this topic at Goldfish Food).

You may be able to feed your goldfish greens and/or proteins just make sure not to feed them to much and make sure your mom doesn’t go aww they look hungry and she feeds them just tell her that you two have it under control
I’ve never heard of the rap your tank in a sweater but I recommend having your tank or bowl in a bedroom or another room that it won’t get to cold or hot if there is a large temperature fluctuate take some of the water out and replace it with water of the right temperature Ally you had a great concern and I hope my input will help you out a bit
If you keep your goldfish inside, the temperatures inside the house should okay. Water temps that dip down into the 60s should be okay. The real problem with temperature changes is, if they change too fast. A small bowl will change temperatures much quicker than a large tank or pond. for that reason, I’d say don’t put the bowl into direct sunlight since it might raise the temperature too much. It’s better for the goldfish’s water to say fluctuate around 72-65 in a day as opposed to say 78-65 if you place it in the sunlight. It’s more about consistency so keep the bowl away from drafty windows, heater vents or sunlit windows. Daylight is good but not sunlight. I’d get a thermometer to test the water temps to see where you are at and try to make sure the water doesn’t fluctuate too much from night time to day time. oh and wrapping the bowl with the sweater might help a tiny bit but just don’t cover the opening which it doesn’t .
In the winters the temperature dips,especially at night.How do i keep my goldfish at a appropriate temperature.I keep the outer glass surface of my goldfish bowl covered with a sweater at night.Is it proper.In the day time i keep the bowl in a warm sunlit room.does this temperature fluctuation harm the fish.Also if i change around 10% of the bowl water with clean water daily and change the entire water of the bowl the next day will it benefit the fish.
