Hi Alicia,
That was exactly our thoughts too, thus we thought we'd start our own.
Our frags are coming along quite well. We've had one learning experience where we had a spike in our alkalinity which has caused some of our frags and old brood stock to STN and bleach. We've now almost rectified the problem and wil be putting in a calcium reactor shortly.
we've also ordered some silicon mould material, so that we can start casting our frag plugs with better consistancy. our old batch of plugs were cast in sand which was not too bad but the tops of them are very hard to get smooth. With the new silicon mould we will be able to get a much better surface all over
