thanks to lauralee here on this forum for giving me the name of the tech at caribsea re my eco-complete and large rocks and off colored rocks.
i was able to talk to the tech in person and he explained quality control was a little lax.
he has offered to make good on the 2 bags i purchased as long as i send him the sales receipt which i did.
im looking forward to getting the 2 bags which hopefully wont suffer from q/c issues.allwet...
