Regular partial water changes promote clean tanks and clear aquarium water. Major changes to the aquatic environment are highly stressful to fish, and even potentially fatal to more sensitive species. For this reason, you can't just get rid of all the old water -- no matter how cloudy it may be -- and replace it with clean water at once. Change 10 percent of the water at a time every two weeks. Have new water standing by at the same temperature as your aquarium water, and mixed to the appropriate gravity if you have a saltwater tank. For safety, turn off any parts and power to the tank. Siphon out about 1/10 of the water and replace it with the new, clean and clear water.

The fish tank will then be manufactured accordingly keeping the upside down fish tank aesthetics in mind. I hope to be able to make more parts of the fish tank move than just the lid. This is where I need to brain storm more ideas. I guess the fish tank will have “moving parts” if I have a pump and aerator as well, but I would like for it to more some more. Another idea that I had was to be able to grow plants on top of the fish tanks as well. Please let me know if anyone has any input. Thank you!
