I have been slowly replacing my base rock (mostly tufa) with other rock. I have had the tufa in my tank for a year and a half and soon .. well I'm going to have too much live rock. If anyone is looking for some tufa for base rock, for darn near free... please PM me...
Oh... 30 ish pounds ... locals only
(some is in my refugium and might have some aiptasia
)
