Yeah sorry, I've got one of those large pumps lying around but it was never worth it for me to use it. I just wound up sticking with tiny pumps, one or two for each bucket.
The problem with large pumps is not only the sound it makes but also the extra heat it pumps into your water.
Unless you're running aeroponics or those perforated tubes that require high PSI, they're almost never worth it imo.
Also, for the manifold style, in reality you can use anything you can tape together and not have it leak. It's just air after all.
