The tub I cured some rock in got stained or just real dirty what is a safe but strong cleaning solution?????????

yes, you can clean with vinegar. You can run a water and vinegar solution in there with a powerhead for a day or two, then go in there and scrub. USE A NEW BRUSH/SPONGE/WHATEVER so that it has no soap.
