The problem with the dc pumps is they have a very poor pump curve. If u buy a dc pump rated 4000gph u will probably only get 2000gph to your tank. Check out efficient pond pumps at the koi pond supply type website s.

I disagree.
Realistically you would be looking at no more than six feet of head pressure or probably a little less.
Granted manufacturers tend to exaggerate flow rates
But, I doubt seriously that you lose 50% of rated flow with a normal under tank sump.

How many drains and what size are they? What about the size of the return lines and where are they at?

The lifegard 5000 pumps will be wimpy for a tank that size. I would recommend using at least two pumps 2-3x more powerful than those.

Nothing wrong with the sump you pictured, but i prefer a large open sump layout. If it was me i would use a couple old 75s or maybe a 125 and diy a sump. If you are stocking heavily, the extra water volume a large sump contains is a great benefit.

Hey there Kyle,
So the plumbing for the interior of the overflows will be supplied with the aquarium as well as the bulkheads that will go through the bottom of the tank, from there all of the plumbing necessary to get your tank running will be supplied with the sump as vinyl tubing and barb adapters and whatnot.
As far as what size and how many, your aquarium will have two overflows.
Each overflow will have x2 drains and x1 return.
The drains will be 1" and the returns will be 3/4".
The bulkheads will be 1" slip.
Let me know if you need any other info regarding the plumbing.
We can certainly subtract the cost of the original pumps and put you into something better like maybe a DC Controllable pump, we have plenty to choose from, I like Current USA, Sicce, and maybe the EcoTech Vectra.
Let me know what you are thinking, we'd just have to chose the right GPH.
This is the email from Fish Tank Direct. My aquarium hasn't been made yet. I can change things if needed. Any and all suggestions are welcomed. Thanks in advance.

Can I run Ultima II 2,000 on my 350 gallon as stand alone filtration? No sump.

I ran a dct 15000 rated at 4000gph 3 ft elevation head maybe 8 ft of 1inch pipe and a few bends and it produced 1500gph measured at max power. The key here is 1” pipe. The op is using 3/4” for the return the small pipe increases velocity causing a lot of head loss. For this system I would recommend 1” at a minimum.

Call me crazy, I'd run the wet dry above the tank as well.

On a 350, I'd honestly save money and run a Ultima II 1000 with a reeflo Swordtail. That is what I am running on my plywood tank now with the media inside. When I upgrade size, I'm going to run that with a large mattenfilter on the back wall and will probably add an overhead trickle filter as well.

I must have missed the part about using 3/4 inch pipe.
If that’s the case then any pump used will be limited.

I see. The setup is adequate, but underwhelming imo. But it seems like it is pretty much taylor made for a wet dry setup. If you were going to run a large sump, you'd want larger drains, larger returns, larger pumps, etc. But i think the idea with your tank is to keep an ideal flow through the wet/dry and if you want more flow use powerheads. Conversely, if you wanted to run an ultima, you'd be better off with a closed loop configuration with larger drains and returns. Im not sure they would work best with an overflow box but could be wrong.

Like the others mentioned, those pumps will only push about half of what theyre rated for around 6' head. I would think they would struggle to keep up with even the 1" drains.

I've run a system very much like you have here. The pumps and system as they have it will run perfectly. If you start changing things then you may encounter issues. Since it's not built yet you could have it designed for the ultima without much issue. Like said above that would work better on a closed loop. I don't see a specific reason why you'd need to go with one over the other, other then preference.

How would I design it for ultima 2-1,000? Overflow should be at 1 end of aquarium and return on the opposite end. 1-1/2" sizing for overflow and 1-1/2" return. I would like to see a drawing with dimension and everything. Im trying to get confirmation that the ultima 2-1000 would be enough filtration by itself for 350 gallon aquarium. Bulkhead placements and all. Can I use substrate and what kind. Or do I need bare bottom aquarium? I want to do this right the 1st time. All my other aquariums are nice. But no where near 350 gallons. I'm running canister and hob filters.

I would tell them you want to run the ultima and let them worry about hole placement. I like a scaped tank and dislike bare bottom.
