I would hope it can handle it, theres over 100lbs of LR
in there. LOL
I really dont' wanna drop a shrimp and wait and I can't dose unless I wanna kill the cuc that hitched a ride on the rock. last time i dosed ammonia I killed off all the coralline that I had and I have alot now so don't wanna kill it.
I'll test again, maybe I'll get a spike from the rock, although it wasn't out of water more than a minute
