Confused regarding size/compatibility

[MGarvo2]

Looking to upgrade to:

VCA Flex Series Ultimate XL Ultimate Return Line Upgrade Kit Dual 3/4 Flex-Series Random Flow Generator​

I have 2, 3/4” Siphon Stopper returns. I want to maintain fairly high flow, so thinking 2 duals is the answer. This particular size says it connects to 1“ to 1 1/4” pipe, and also to 3/4” loc line. Is that the individual arms, or the attachment base? Question is, will this size properly connect to my 3/4” returns? Also, I’m running a Jebao DCP-18000 return pump with about 14’ rise (head pressure). What flow range would you recommend for 2 dual RFG’s of this size?

From a fitment stand point, that kit, the Ultimate XL Return Line Upgrade Kit – Dual 3/4 Flex-Series RFG , with its includes adapters and 3/4in Loc-line, will fit a variety of scenarios.

If your 3/4” Siphon Stopper returns include 3//4in Loc-Line, then this kit will fit directly to that.

I found this:

3/4" Siphon Stopper® Return Fitting - Custom Aquariums

The 3/4" Siphon Stopper® Return Fitting will keep your aquarium return line from back siphoning in case of a pump failure.

www.customaquariums.com

But it doesn't specially say that the modular hose is 3/4in Loc-Line, and it can be hard to tell he difference between 1/2in and 3//4in loc-Line from just a photo.

You can view this guide that shows different way to determine what size you Loc-Line is

if you can confirm that the module hose that Siphon Stopper comes with is genuine 3/44in loc-Lone, then it will fit

Next - regarding the pump/flow - if I am ready this correctly, and your head height is 14ft - then based on the pumps chart, you will be delivering less than 1,188 GPH - after head loss.

If that is the case, then I would suggest at dual 1/2in RFGs Which you can do this Kit. This dual 1/2in RFG will fit directly to 3/4 in Loc-line

OR - better yet - go with single 3/4in RFGs on each out let. You can reconfigure the dual 3/4in Lit you originally asked about down to a single 3/4in. You can disconnect the arm and then that will connect directly to 3/4onm Loc-line.

That would give you the options of running gin either configuration.

Hopefully that is not too confusing. if you need addition help - please feel free to just give us a call.
