need help sizing up a new sump pump

I'm debating between the Sicce Syncra 3.0 or 3.5 and the fluval sp2 or sp4. Also considering the Vectra S1.

I'm looking to replace a Jebao DCT 4000 running wide open that is having some reliability issues. I like DC and if it takes spending for a Vectra I'd do it if they are any more reliable. I want quiet but need a pump to work when I'm out of town.

I have a 90 gallon tank and I'm guessing I need about 600 gph at 4 feet head.

Thanks
 
I guess what I need to know is if people are running either the sicce or fluval pumps on a 90 gallon, and assuming the normal head height with a pump underneath the tank, which model did you go with and is it a good flow rate.

For Fluval it seems I really need something between the sp2 and sp4 but they don't make a sp3. Sicce is odd in that the syncra 3.0 seems to have more flow at 4 feet than the 3.5

Of course the Vectra is adjustable and I assume the S1 would be plenty for me. Its just triple the price and a DC pump which I'm still not clear on how reliable it really is vs the AC pumps above.
 
IME all of these pumps are made with the same source internal parts. If it were me I'd upgrade to the latest Jebao DC model. I've run my 9000 on a 90g for 2+ years with 100% reliability. Cleaned only once a year.

I know it's not what you are looking for brand wise, but just keep in mind my opening line.
 
Stay away from the Vectras, too many problems including heat transfer & failures.
Fluval's are one of the most reliable pumps & a valve on the return side will give you control over the flow.
 
If you need an affordable pump that you can be comfortable with while out of town look at a proven AC motor; the Fluval was a good start.
 
I had a Tunze return on a 90 gallon for about 2 years with zero problems. I think it was a 1072 but its hard to recall as it was several years ago.
 
Tunze rarely puts out a product that is not reliable, I buy Tunze with confidence when I do; I guess these get less attention (as DC return pumps) since they are relatively small and probably developed originally for their skimmer lines.

Also, since you had mentioned a goal of 600 GPH, just be aware that it will probably be 500 GPH with head at max power.

Thanks for that. I went with the 1073.06 for a little more power in case I need it. I just couldn't decide between the fluval sp2 or sp4, neither seemed right and I'm not spending on power just to valve it down.
 
Yeah I just installed an overpowered DC pump, nice to have the ability to turn it up (if your drain can match it), threw on a sock and got my tank to 20x turnover and blasted the rocks. I’ll be taking advantage of that periodically. But normally I’ll be at like 30%, being efficient and hopefully less wear/tear on the pump.

Why 6? Have not heard much was going to suggest a sicce 4. I have the.04 impellar lasted about 5 yrs great pump, if i found a deal on a 6 would go that route for 100 gal system
 
Well I got the 1073.06 and honesty I didn't realize that its completely different than the .05 which is a DC pump. The .06 is an AC pump. Oh well, its probably that much more reliable and while a bit noisier than a DC, its well within acceptable and supposedly it will get quieter after 2 weeks of operation.

I was leaning a bit toward AC anyway just because reliability trumps the little bit less noise though I did like the idea of being able to turn down the wattage. At least the .06 has a built in adjustment on the intake to allow for flow control without having to valve it on the pressure side.
