oh ic.. omg.. no wonder the one i brought from last time is ok until now.. but the newly brought one.. 80% percent gone.. .
but so far.. for now.. its ok.. cos i din add any more fish..
but later will heh..

btwn how to avoid sudden ph rise? ketapang will surely lower the ph.. but it help me to prevent algea attack my tank.. any way to intro new fish to settled tank? normallly i jus mix the water tht got together wit fish while purchasing with settled tank..
