Hey Lando,
Is the water supposed to stay clear when the rock is done curing? I have about 25 lbs curing in a garbage can right now and the water is super brown :/ I know the rock is done curing once ammonia and nitrites are 0, which they're nowhere near, but I dont want to funk up my tank by turning the water brown.
Also, would a filter help with curing? I have an extra filter I can run, I just don't know if it will help or not. Right now I'm just running a powerhead. Thanks.....
On topic, nice rock Steve, it's got some sponge and corraline-->excellent. I'd check your ammonia levels in a day or two to see if the rock is cured. It's too early to know. And believe me, you'll know right away.
