2 smaller skimmers vs one larger

[Mark...]

Question. I have a total 225 gallon system DT (180) and basement sump. I'm currently running a Tunze 9410 for the 1st 18 months of operation. It is within its rating, but as the bio load increases I might need a larger skimmer. Since I have room in my large 6 ft long sump I was thinking of just adding another Tunze 9410 instead of going bigger and selling the original. Nice part is the Tunze only uses 15 watts. Looking for feed back on this idea.

Thanks!
