Thanks Gresh, your frags are all diong very well! You'd be a proud Pappa! Good to know about the limited durability pf the Kordon bags and will take special care when shipping frags. May limit it to softies as acros and hard corals may puncture. Is it possible to double bag for more durability? IM me if you wat to mail me a few of the bags and I'll give you my address! Thanks again!
