Sicce syncra 2.0 or Jebao dc6000??

[Gdk414]

I am trying to decide which one of these pumps I'm going to use on my 90 I'm setting up.

Any opinions? Thanks

I have the dc6000 in my 50 gallon and have it at the second last stage.
I would go with the 9000 if I were you for a 90. You could always dial down the power if it's too much.

If it's for the return pump, I wouldn't bother with a DC pump at all. Unreliable by comparison to an AC pump. At least to me, there really is no other feature a return pump can have than longevity. ;)

I'd pick up a right-sized Eco+ before that Jebao.

I really do like Eco+ for a cheap pump, but in seriousness: Mag drive or Sicce.

Folks instantly poo-poo Mag pumps for noise and power/heat.

Consider that any "extra" heat added merely gives your heaters a bit of a break – under most circumstances it's not that much.

Also consider that I've never had a problem getting one to be as quiet as I needed it to be. (Which is to say more quiet than my skimmer.) I believe they are a stronger, tougher pump (based on my experience with them) that most of the other options, even if they aren't the most quiet.

(I admit that I'm about to try out one of the new Chinese-built Quiet One 4000's. My motor block on my old Italian/Sicce-built 4000 appears to have taken a permanent break – seems like the heat protection circuitry trips as soon as the impeller starts to spin – and I still have a spare impeller for it! :mad:)

Jebao would be more flow. The Sicce wouldn't be large enough. Maybe the 3.0 would be better if you're pumping from a sump. Jebao has the new DCS model so look for that. I noticed right when I switched for a AC to DC the temp drop a few degrees.

Ok thanks. I have both of these pumps because I got a great deal on some used equipment and this is my first sump setup.

The measurement is from your sump water level to the top of the return. You have to include significant plumbing features such as 90° bends, etc.

Can you post a summary of your plumbing, maybe a picture of it too?

 

[mcarroll]

The 2.0 might be just fine

I would point out that you can make up for lower flow through your sump with additional flow from powerheads. You just need to be mindful that it also means less water turn over for your skimmer so you might not have as much nutrient removal as you would with higher sump flow.

 

[Gdk414]

It is going to be hard plumbed. Regular durso overflow. Prob 2 90 degree bends

 

[Gdk414]

I didn't really check the specs. Thanks this is all good info to consider

Instead of doing 90's you can do 2 45's to improve flow. This is what I did.

I like that. Thank you I never thought about that. I'm practically brand new to fish tanks and this one will be my first tank with a sump

If you have a good plumbing supplier (or shop online) there's also such a thing as "Long Radius" or "Sweep" Elbow, which more or less is what you're simulating with two 45º's.

For example:

3 in. PVC DWV 90-Degree Hub x Hub Long-Turn Elbow

I would not be overly concerned with your flow rate. As long as you are turning over your display volume 4x (3x minimum I would say) an hour that's plenty. After head loss, shoot for 360gph give or take. You can always go more but it is at the cost of more watts that runs continuously.

Of the 2 brands you are looking at, IMO the Sicce would be a better pump.

Assuming there's no other fittings and that you'll have four feet of vertical and five total feet of plumbing and are stuck using the 3/4" return plumbing on the tank:
(http://www.freecalc.com/fric.htm)

Here's with regular 90º elbows:
Pressure Loss (psi): 0.39 Head Loss (ft): 0.9

Here's just switching to long-radius elbows:
Pressure Loss (psi): 0.36 Head Loss (ft): 0.8​

Actually not too bad at this flow rate.

But here's if you could switch up to 1" return plumbing, but with regular "tight" 90º's:
Pressure Loss (psi): 0.14 Head Loss (ft): 0.3

And with long-radius elbows:
Pressure Loss (psi): 0.13 Head Loss (ft): 0.3​

(using two 45º's actually calculates the same)

So the plumbing generates an additional 1 foot of additional head pressure in the "worst case scenario" of 90º's and 3/4" plumbing.

4 + 1 = 5 feet = 1.52 meters

The Syncra 2.0 should be perfect. Right in range with this plumbing setup. About 317 gallons per hour.

Find a way to upgrade the plumbing to one inch to get a boost, but it should should not be necessary.

Nice work! Personally, I would want a little more than 3.5x tank volume for turnover but I do agree it is fine to start with and can always be upgraded later.

I think that the Sicce is the better pump, from personal experience. It is quiet and won't go out on you, and it gives you enough flow for your first tank. I assume that you aren't going to try SPS right off the bat, so this level of flow will be fine for a first tank.

Get a sicce! I just got one and it is amazing you can't hear it at all! Plus sicce as a 5 year guarantee!

Didn't know that! Always like a stout warranty. :)

(Though mine that I mentioned earlier was dead at just over five years. I should also add that while it looked fine and mostly clean when it died, I never took it offline for servicing once. So five years of continuous service. I won't say it's great, but it's not horrible.)
