I still remember one problem I used to encounter before when I change Ishy‘s aquarium water. It’s how I remove the dirty water and fill the aquarium with newer and cleaner one considering that I intentionally and perfectly situated the aquarium in the topmost part of our shelf in the living room. Just imagine how risers like firm wooden stools were of best help to me then. My brother also suggested me to use plastic hose in removing water. During that time, I have had no idea what hose to use but only the electric thermoplastic hydraulic hose to help me remove those water.

Anyways, that was before and I already learned how to remove water from the aquarium using hose and just let the water flow through it when my brother personally showed it to me when I went home and observed him how he cleaned his aquariums.
