my tank is up & running & established .
when i first started i bought some l.r. & base r. after months i took out some base r. & added more l.r.
the old base r. is in my basement ,dry .
ques. is - what should i do to introduce the old dry base r. back into my tank???
cure it ?? or just add it to tank ??
thanks for your advice -- oldfishead !!!
oldfishead says "keep it wet"
