Reducing the intake of a pump? yes or no?

[Leslie88]

I got a 100 gallon water container to premix my saltwater. It has a 3/4" bulkhead. I just want to attach a pump for circulation and pumping it to my system.

I have several Blueline HD pumps laying around, but they are all 1". I would never reduce the intake for my actual reef. Think it matters just for this?

Thanks!

No not all. Just reducing flow but it won't damage the pump if that's your worry.

Wont matter at all for that application. Just reduces total flow a little.

If you do find it causes cavitation which is very possible, install a ball valve on the discharge side of the pump and restrict the outlet to match the inlet. Once the in and out are matched it will go away.
