@Viva, so the rocks on the right shouldn't have that large gap?
@MF, actual lace rock is volcanic and inert. There are some rocks called lace rock which contain significant amounts of CaCaO3. I don't believe these to be those but I won't know for sure until I flood and monitor. I've already treated with acid and everything seems okay.
@aznrice, yep that's right. This will also be a test for the bigger tank.
