Doubling my skimmer or not

[gregzz4]

I'd call your's a 260g system, for purchase sake

The reason for halving a skimmer's rating, as far as I understand, is because many of the lower-end, less pricey skimmers have poor air intake values
Basically any skimmer under $500 needs it's rating cut in half

My Skimz SK181 Kone is rated up to 320g, but has only 540l/h of air intake, so I feel it's good up to 160g and works great on my 110g system
Most of the high-end skimmers are closer to or even over 1000l/h of air, so their ratings are pretty much bang on

About recycling skimmers ... I know nothing
