mini water fountain in hdb..feasible idea?

hi all

i am thinking of installing a mini water fountain in the balcony of my hdb apt.

do any of you know the costs of such fountain ? is it difficult to maintain? how often must we change the water? and does it use a lot of electricity?

i think having constant flowing water is a good symbolism of good fortune and wealth flowing in.


hmm... in that case, where would be a good spot to place this fixture? near the door , facing in, towards the direction of living room, meaning fortune flowing from outside into the home???
