Live rock safe?

[Beau_123]

So I have had some live rock in a make shift qt and last week or so I shut off my little filter and there is no more water movement so the water has been still for a while and I was wondering if it is still safe to use the filter and put the live rock back in my display tank please help.

Get your water flowing and run an ammonia test
