Yes. I contacted them twice now and they won't return my emails. They have a pretty good deal it seams with a buy 4 get one free.
Have you searched for the sand other the other names its marketed under? Old Castle, Yardright are a few names that southdown is relabled as.
Absolutely! I also attempted to contact Yardright and they too do not answer my inquiries.
Right now, I have ~2" of the medium grade Aragonite sand from Carib Sea. I plan on removing half and then allowing the system to settle a couple of weeks before removing the rest. I really want to do a DSB
the right way this time, but I would rather not spend $1 per pound when there are other options.
There is another post on some possible alternatives, but nobody will say definatively if the sands noted are worthwhile:
The whole silica vs. aragonite thing baffles me as well. In fact, I had a huge diatom bloom with my current aragonite sand toward the end of my cycle, something that is supposedly a silica trait.
