kalk
 

finally got rid of the liquid calcium additive and am dripping kalkwasser.i went with the seachem reef kalkwasser.on the label it sayscalcium (ca) 54.09 o/o.is this number telling me that this stuff is only 54 o/o pure calcium hydroxice?and how many ppl are using this particular brand and where would you compare it to other brands?

also the bootle doesnt say much about mixing it what is the best way to mix it?im using it in a drip/topoff setup.how long should i mix it for?
