Best pump choice?

[Cory]

I want a a return pump that doesnt have the chance of leaking current or inducing electricity in the water. Any suggestions?

 

[MSB123]

For what tank size? How much turnover do you want?
You are looking at an external pump for a 0% chance, but most DC internal pumps are very sturdy and reliable.

 

[Cory]

The tank is 220 gallons. The more flow the better. 3 to 6000 gallons an hour.

As long as you go external you should be good. Wheather external DC or AC.

There really aren’t that many options in the 6,000 GPH range If quite is a priority you can go DC I use a VarioS 8 and have been very happy. If reliability and durability is king it is still very hard to beat a Japanese Iwaki. If you have unlimited money an Abyzz could give you the best of both worlds.

Yes thets so true. I think reliabilty and durability is s good choice. I just dont like the poor flow rates of iwaki for the wattage. Noise isnt an issue since its in the basment. Abyzz not until im rich lol. 2400 gph is my minumum pump needed.

 

[Cory]

I was looking at iwakis insides. It seems its very safe as far as electricity goes no?

You do not say what kind of head height you have but since it is in the basement I would assume 15' plus. Not a lot of options to get 6000 GPH. Reeflo Tiger Shark

 

[Montiman]

I would never by another reeflo. They are quiet but seem to blow seals randomly and put gallons of water on the floor.

Keep in mind with an Iwaki that even though the flow is low the head height is amazing. An Iwaki 100 is rated at 39 feet of head while the VarioS 8 I use is rated at 18 max. Depending on your head height you will likely get more flow from an Iwaki than many DC options because the head will restrict flow fast on most DC pumps.

Pressure rating doesn’t come for free so you have to expect more power draw if you want it.

I had a Reeflo Hammerhead that would fit your spec of an external pump and 6,000 GPH. I used it for a limited period of time because it was too much flow for my application so I can't speak to reliability.

 

[Potatohead]

Good think about an Iwaki is you will set it up and not touch it again for like five years, or more.

 

[KStatefan]

Have you thought about running two pumps? That might you you more options to get 6000 gph at 10-15 feet of head.

 

[Potatohead]

Also I have to say a 220 with say 80g in the sump you only need about 1000 gph (actual flow at your head height). 6000 gph is crazy. The 30RZ is meant for high head and will do about 1200 gph all the way from no head to like 20 feet I'd probably go with that. It doesn't start falling off until nearly 30 feet and it also uses under 100w. There's also a 40RZ not shown on this chart if you want a bit more.

No the tanks down their too. Its about 6 feet of head maximum.

Ive read that about hammerhead pumps too. Wont buy one for that. It would be nice to have high pressure to be able to make a venturi skimmer.

No i wouldnt thats too much cash for two iwakis lol. But i dont need 6k, just 2400 to 6000 gph.

My tanks sump is above it. It is q sump/carlson surge device. I neeed a minumum of 2400 gph to make my surge work.

I wonder what type of power from an Ecotech Vectra S2 1400 gph on a tank with about 5ft of head.
I wonder if I should get the 2000gph to be safe. My pvc will not run any more than 5ft. will the S2 work? tell me what you guys think. I don't mean to jack this thread but I figure i was coming here for this very thing and i would join the discussion.
P.S
the tank is 180 gallon 6x2x2 or marineland 180

Noisy, bubbles, and HUGE salt creep

A Tunze wave box would be my first choice

Second would be a closed loop with oscillating DC pump, with eductors

 

[Montiman]

When I worked at an LFS we did dozens of 200 gallon ish installs with Iwaki model 40s. I can’t remember any complaints. I don’t think there is a reason to go crazy big on your return pump.

 

[Cory]

I think ill go with a pan world. Are they good?
