Reef Octopus Varios 8 Return Pump setup

[Ashir Parekh]

Hi Guys, So i have a Varios 8 Return Pump. I went to big with the pump as my 2 tunze wall overflows can only handle around 1500l/h each so roughly 3000. My issue is the varios pump is 10000 l/h and is controlled via 5 speed options only. I assume 1st speed is at 2000l/h and second speed is at 4000l/h. I need to be in between. Can my profilux 3.1 fine tune that and bring it to 3000l/h? If it can, what is the best method to do so?

Many Thanks for your help guys.

If it is this pump

Protein Skimmers

Shop Protein Skimmers and reactors on bulkreefsupply.com. Read reviews and compare protein skimmers and reactors.

And it has a 1-10 volt port you would need the cable for the 1-10volt port and then you would cut the cable as it not designed for the GHL 1-10volt port .

You would then purchase the breakout box.

Breakout Boxes & Adapters - GHL Advanced Technology

Breakout Boxes & Adapters enhance compatibility with ProfiLux systems, allowing easy connection to third-party devices via S-Ports or L-Ports.

And connect the adapter cable to that. Then program the 1-10 volt ports to a stream pump and then program the stream pump in a stream group.

Hope this helps.

Does the pump speed become infinitely adjustable, then, via the GHL, once all that is done? The control that comes with the Varios only has 5 speed settings....

Not going to say infinitely adjustable, but asking if it has more then 5 settings the answer is yes. Your now adjusting the voltage and not using the 5 preset settings that the unit comes with.

Thanks! That's what I was thinking but couldn't seem to find the answer from somebody that actually KNEW!

I also wondered this. Thank you

New to all of this but couldn't you put a bypass after the pump with ball valve that dumps excess water/pressure back into the sump?

I have a Varios 2 pump linked to my Profilux4 and using a GHL flow sensor, the Various is set to deliver 500 l/h.

The reason I want a controlled flow is that prior to the display refugium a UV is plumbed in so the flow needs to be at a specific rate.
