What Rich said! I am amazed at how many people have already contacted me so far so I will try to get back to you all tomorrow if not tonight. FYI we have a ton (literally) of this stuff so we should be able to get some for everyone and we are not in a rush to get rid of it.
Also, some FAQs:
Where did this rubble come from?
The rubble has been in our large reef tank for the last three years. It has been exposed to corals, clams, fish, etc. and will still be damp when you get it.
Can I use it in a calcium reactor?
It is the proper size but theoretically calcium carbonate kept in a reef tank will have a higher coating of phosphate on the outside. I would give it a rinse in vinegar or diluted muriatic acid to wash off the outer layer, or run GFO on the output of the reactor. Either way, we can't make any guarantees about its usefulness in a reactor. Having said that, it should work fine.
Should I rinse it?
Yes, definitely. It will be "dirty" as it was part of a sandbed, and has been exposed to our tank inhabitants and all their potential parasites. I would soak it in freshwater for at least a few days.
Do I need to bring a container?
Yes, bring a container to hold the rubble. We don't have any containers to give out.
When can I pick it up?
I work Tuesday through Saturday, and you can come by tomorrow (1/21) if you arrange with me via email ahead of time and can come in the afternoon. Generally Tues - Thurs are the best days to come pick it up, but Fri/Sat can work too if necessary. PLEASE DO contact me ahead of time, and PLEASE don't show up on these days without notice, as I have a busy schedule and am not always available to meet people at a moment's notice.
Thanks,
Matt
