Again, do not necessarily need a skimmer on a 20G, but weekly water changes a must-- just more water to change!
Some difference,
- Twice the amount of LR
- Twice the amount of sand
- Different Light
- Couldn't find what you were going to do about powerheads with the 10G, but going with more than one powerhead generally decreases the chance of dead spots in the tank. As seffie said earlier, 10-15x flow would be great.
