no, you cant cure it in your display tank, since it leaches out stuff from the concrete and also makes your pH fluctuate. its pretty easy to cure it, just put it in a rubbermaid outside and put your rocks in and fill it up with water. everyday, dump the water out and fill it back up with hose water. do this for a couple of months 'till you become more confident then you can shorten the time up when you know its cured.
and i dont have any good shots of my display tank ATM. i'll post some pictures of it tomorrow when the lights come back on. its nothing special, but i think its getting there with some special attention. trying to let it grow out, but its kinda hard when you need your 1.5 year old MH bulb replaced, and you dont have cash. lol
