I was rinsing the gravel for my 29 gal in a kitchen sink. The sink kept filling up and little bits of gravel kept slipping through the siv (probably misspelled). Anyway I was getting frustrated when my girl's 10 year old brother suggested we use a big cooler and a water hose. The cooler had a hole with a plug in the side near the bottom so it didn't fill up like the sink did. So I held the siv with one hand and the hose with the other. I found this to be a much simpler process so I thought I would pass this bit of advise on to you. Any corrections would be appreciated.
