Well hey, i mean, if you have the time to cure the LR
yourself, which really isnt that hard, then go for it. It would be a good experience for you as well so just incase you need to do it in the future, or you just want to know how. All you need is like a small rubbermaid container, since your not getting THAT much rock, and if you have an extra powerhead, just to keep the flow going, and a heater to keep it warm obviously. Leave the rock in the container with everything on i think for like a week or something.. not 100% sure on the time for curing, but i think its either a week or two weeks. Hope someone could chime in and correct me on this one if its wrong.
Or.. get the fully cured rock. xD
