Hi all, wish to share my experiences regarding water features. I shall not say anything on good points regarding water features...most of them are nice looking, fengshui purpose or etc only. Now I shall contribute some extra consideration factors if you are in the process of it. Water feature with miniature fiber tank or big pot. - Water very difficult to replace, especially if you got deco inside(marbles, rocks..etc) Must keep fish, or at least water must be active flowing to prevent mosquitoes. - Not suitable to have big fishes. Bigger the fish..more waste from them. Considering the little amount of water..unless you have a big and good filter system. - If pump is cover under pebbles or stones, make sure water level is alway enough, else pump will spoil. - Always need to replenish water(cannot lazy)...water evaporate off(You will be surprise how fast it it). Especially those with water feature rocks, dripping, spilling, spitting, or any other effects you can think of. - You ever keep fish tank before and gave up after some times? Consider it for the water feature as well. - Most of the times, especially those feature with water flowing/spitting down effects. Water will 99% spills out of the tank itself. Don't believe? Look carefully. Or when you visit all these shops..you can check out too. - Algae...you can never prevent them from growing inside unless got very healthy filtration system or you put in chlorine water/block to kill them off completely..living things die too. Why the floors abit moist or wet surrounding the tank. Even at shopping centers. ...blar blar blar...the list goes on. For me, I totally gives up on having water features. Well, my experiences are based on myself. May be different for the rest
