Hey reefers,
I currrently acquired a few 55g plastic barrels that I am wanting to use as water starge units. The barrels were used for holding soap at a car wash. My question is how long should I flush them out before they are safe to start storing water for my aquariums in? I have rinsed both out for about 16 hours each, with the hose on 75-80%. Is this good enough? Is there anything else I should do? Looking for advice please help.
