I used the Caribsea Aragonite in my build thats on-going at the moment, and it took me close to 1.5 hours per bag to clean it up!40lbs of caribsea aragonite special grade dry sand arrived. First 20lbs or so being rinsed in a bucket. Just pouring the sand from bag into bucket there were clouds of dust. Put hose at bottom of 5g bucket and poured a few cups of sand in, then put smaller bucket lid over hose and sand, then added much more sand on top until about half the sand bag was in bucket. Turned on water slowly, raised flow, saw lots of silty water coming out.
Ran for ~15m, water clear, but I see most water from sand is coming up from one spot. Going to drain the water, transfer sand and hose to 2nd bucket and start a 2nd rinse.
