I was given 2 Pulsar 170 powerheads, so I'm unsure of the specs . Company is Tetra/Second Nature. Could you give me the flowrate?

There's also a removable rubber grooved pad inside on top portion of PH. What is that?

thanks.

hmm i guess deductive reasoning tells me it's it's some kind of filter or that it creates air bubbles. It's associated with the knob that adjusts the amount of air bubbles coming out of the PH.

thanks anyway.

It's for a 20G high sw reef tank I'm planning.
