I also have a manifold with 5 taps on it so some of the flow is diverted to reactors also. I currently have one on it for carbon. I did have a biopellet reactor and and calcium reactor but those are not on the system now.That does make me more confident about using the 3/4" on my system! Thank you.
About 3.5 feet.3/4" returns is fine, unless you have a long distance to travel.
Do you mean there's more wear and tear on the pump?
I see, thanks!No, major drop in output.
One of the advantages of DC pumps is that they are variable. You don't need to "choke" them, just dial down the power...1",
DC pumps dont like to be choked.
It's a Sicce Syncra Silent... You're all goodI just realized I mixed up DC and AC pumps for a bit there. Mine's an AC pump, the Sicce Silent 3.0 not Sicce Syncra.

I have 5 barb fittings on mine between the pump and the return back into the tank. One is on the pump itself. The Sicce 3.0 suggest 3/4 return tubing for that pump. Below is a photo of my sump with the Sicce 3.0 inside and the fittings and tubing for it to connect to the manifold. The mainfold has a ball valve and a barb fitting to a hose which goes up to the overflow which also has a barb fitting for the hose. The overflow even has a venturi on on it for starting the overfloe. It is probably more of a restriction than the barb fittings. There is also some flow diverted to the carbon reactor also. I don't have any good photos of the manifold except when the stand was under construction. The last two photos show the manifold between the other two PVC pipes which have the wiring running from the back cabinet to the front of the stand where there is an enclosed area for electronics behind the front door of the stand. The manifold has 5 ball valves and outlets for return line and other reactors as needed. This is on a 42 gallon hex tank and it has enough flow for the return back to the tank. The tank has 2 MP10's for flow in the tank.Yes I'm worried about that barb fitting between the vinyl tubing from the pump to the PVC pipe as well. I ordered one for 3/4" tubing online but didn't realize how small the barbed side would be till I got it. I think I need to get something else. Is there a fitting that the vinyl tubing would fit into (but stay in reliably) instead of having to go over?

I just measured it and it is 1" outside diameter. I found some in my unused tubing that was 1" outside and it measured 3/4" inside. I believe that was left over from what I used to attach the pump to the manifold with. If I remember correctly the fitting that comes with that pump is 3/4" barb.@n2585722
What size hose do you use? 3/4" as well?
I’m building my umpteenth build and am asking return and drain plumbing questions!! No shame. I’m freaking out here too and second guessing my choices.I feel like I've been making too many boards about this project but it's my first time plumbing a system and anxiety is a huge issue. Don't want to have to redo this later so looking for some final advice before I start cutting my pipe!
My system:
I planned to use 3/4" pipe for the return but then came across some posts to the effect that 1" is better for over 300gph because of friction. Thoughts? Is it worth going up to 1" to be safe?
- 40g tank + 16g sump + possible addition of a second 20-25 display tank later = 81 gallons max
- max 5x turnover, about 400gph
- total head loss ~ 6.5 feet
- Sicce Syncra 3.0 should be capable of about 460gph at that height according to head loss chart (might upgrade to better pump later)
Thanks in advance!
I really appreciate that, thank you!I’m building my umpteenth build and am asking return and drain plumbing questions!! No shame. I’m freaking out here too and second guessing my choices.
