To change, or not to change?

[Johnny Reefer]

One thought is to run a canister filter full of nothing but poly-fibre to mechanically filter out all that crap. I've never cured LR before, but I've always done this when setting up a new tank with new aragonite substrate that has clouded the water.

HTH,

The NH3 levels can become quite high during the curing process, which will definately reduce the life on the rock. Stretching out the process by a week to preserve this would be better in my mind. I've always done changes before and always seen pods, etc shortly after. This time, without changes, I see nothing.
