Cool, just keep an eye on it as things change over time, like I mentioned algae on the overflow guard, check valves not sealing properly and additional equipment like skimmers and reactors all add up. If you increase your return flow that will also increase the blow back.

I'd say running the skimmers side by side is perfectly fine, if Mindy is correct you'll notice the first skimmer is obviously doing a better job than the second but I'd bet you wouldn't notice any consistent difference between the two to suggest that is the case.
