LR + Acid/base neutralization = good or bad

I would also use a good highflow pump or 2, as there will be this brown slimy deposit on the rock surface after the bath. i did not have a pump and had to scrub this off with a new dish scrubber with semi stiff bristles

also for the sake of arguments i did this last week. i bathed about 25lbs of rock. rinsed and scrubbed and then rinsed again. now to double check that all phosphate were gone let the rock sit in tote with fresh ro/di water for one week. tested last night and there was still a low # of phosphate @ .5ppm so maybe a second light bath would help as well, something like 1p acid to 20p water other opions on this would be great
