Varios 4 question

medskie · Jun 27, 2020

I need some confirmation on what this pump can handle. I am currently ordering plumbing for my new tank which is a SCA 75 (36x24x20” 12mm rimless) gallon using an herbie overflow. I am adding a manifold for a BRS dual reactor(carbon/gfo) and a second connection for any future equipment(maybe a calcium reactor) I want to use. Will the Varios 4 be able to handle this or should I consider going for the Varios 6? I'm fairly confident it would be enough flow for the dual reactor but I just want to get some insight from other reefers using this pump in their sumps.

Any tips for plumbing the return manifold if you have them! I will be using unions for most of the connections so I can adjust my plans if needed.

Thanks!

FWIW:

Don't run your cal reactor off the main return pump and or your manifold, the effluent rate won't stay stable doing that.

Been running the Sicce .5 (Tunze Silence) as my cal reactor's feed for way over 1.5 years, with the GEO needle valve and it has worked flawless. Put the needle valve on after the second stage.

Streaming the effluent at about 280ml per min.

Good luck on choosing your Varios

Thanks for the info! This will be my first time using a calcium reactor and after a bit more research your tip makes perfect sense. Appreciate it!

My various 4 runs my 60 cube return and manifold with a media reactor. It does this easily at around half speed. I don’t run a lot of flow through my sump but it’s got two more gears if I feel like adding equipment or upping the flow. For what’s its worth

My setup isn't much larger than yours so I figure the flow should be more than adequate. Thanks for the reply. Cheers!
