BM Skimmer Ratings

[Potatohead]

I would go with A5. It's nice to have a big skimmer but you also need a big bioload in that case, that's the whole point of a bigger skimmer. There's also a good chance the pump on the bigger one pushes way more water than your return pump which means the thing will be re-skimming already skimmed water all the time. I actually have that problem a little bit and wish I went with one step down.
