thanx justdave, good to hear from a pro
NSW user. there is mention that you should let it stand to allow you to raise the temp and allow setlement. and that this should be done while airting to keep alive all that good free food.
also while sihponing into the tank allways leave an amount at the bottom so as not to disturb the settlement.
is this true and do you have a set time? or is it best to reach the paramiters as quick as posible so as to preserve as much free floating live stuff?
