My 120 gallon reef has been bare bottom for about 3 years now and I'm thinking about adding sand this weekend. Can I add a 2 inch sandbed all at once or should I space it out a few days? Id rather get the sandstorm over with all at once. Also any tips on adding sand other than using PVC tubing? I've rinsed sand before but it takes forever and makes it a huge pain pouring it down the PVC
