Last time succesfull breed C/D grade crs (from begining 10 piece to more than 100 piece..

) so got enaught confidence to start for better grade CRS, but not so succesfull,

buy 11 piece grade B/A CRS from East aqua, but now only leave less than half..Haaa...so disapointed..plan to set up a better equipment 3 feet tank in the future, coz the B/A grade CRS is lot more sensitive than the C/D grade CRS..by the way, anywhere in Malaysia can get fine grade CRS, and any second hand TDS pen for sale?
