At last finally i managed to make my aquarium tank water become crystal clear fresh water after several effort of trial & error with a stong hold on patience just keep on trying without giving up.. (^^,) for about this past few weeks.. - i guess!- & yet i've noticed that not every product that we are use for keeping our aquarium looks nice & crystal clear water such as some of not so called branded water filters (eventhough some of it are quiet exensive & apa tah lagi yang murah..langsung useless...),anti chlorine water product, anti cloudness water and etc..that we purchased from our local store are very usefull to use. Therefore for those who are begginers like me its most recomended to take alittle bit of research & some knowledge about aquarium tank fishes care either through internet or in what so ever means... before putting lots of money into it...
