Return Pump Tubing Size?

[Res_Ipsa]

Howdy everyone. I'm curing my rock and a few weeks away from getting water in my tank. One of the upgrades I did for my Innovative Marine SR-60 was to buy two Sicce 2.0 pumps to replace the stock Innovative Marine returns.

BUT, the stock pump barbs and tubes appear to be 1/2" ID whereas the Sicce outlet barb looks like 3/4" ID. All of the soft tubing plus the bulkhead appears to be sized for 1/2" tubing.

My question is whether I should buy a fitting to bring the Sicce outlet down to 1/2" to match the factory tubing OR whether I should drill the bulkhead and buy new tubing to match the Sicce's output. I've never drilled acryllic and don't have the tools for that, so I would need to either find someone to help or do some more research on how to do that.

I’d just go with 3/4” to 1/2” barbed reducers for simplicity’s sake. Go to Home Depot, grab a couple of these, and call it a day...

Thanks @Water Dog. I did some digging around and decided to run 3/4" hose to these 3/4" to 1/2" reducing Y connectors to split the pumps into the 4 return nozzles.
