• Help to select a pump for returning from the atmans.

  • Robin

I seek advice on choosing the pump power for returning water from the sump... the volume of the tank is 90 liters, the volume of the sump is 39 liters, and the height of the lift will be approximately 1 meter. What pump should I choose, as I have never dealt with this before???? I would appreciate any answers and advice!!!

Natalie

Well, we need to reduce the power by about half.

Mark

He recommended you correctly. The pump, Hydor Seltz L20, 700 l/h, is quiet and reliable. The price is excellent. Of course, there are better options, and naturally, they are more expensive; it all depends on your budget.

Unfortunately, we are considering a budget option for the sea, so I am looking at Atman pumps. Based on your advice, if a 700 l/h pump is sufficient, then an Atman 1100 l/h should be enough, right?

Erin

1100 l/h is a lot. It is considered that you need to pump about 5 times the volume of the aquarium per hour. In your case, it is 450-500 l/h. Moreover, Atman pumps are significantly noisier than Hydor Seltz.

Charles

Well, it's noisy, but we'll have to manage with this. The Atmans are 600 and 720, but in the first one, the lift height is 0.85 m, while in the second one, it's 1 m, meaning that in the second one, the lift height is just barely enough, it might not be sufficient.

I recommend installing a valve on the outlet pipe so that you can adjust the power; otherwise, you'll end up with a "storm in a glass."

And also, is there a difference between the series Ad and pH 1100, which one should I choose????

Jill9137

Take one that is 1.5 meters high, 300-400 liters will be enough, no more. There won't be a storm, it's been checked. The pH may make noise!

When I was choosing the pump, I was discouraged from this model (even though it was more powerful). The argument was the iron shaft and the knocking after a couple of months.

Curtis

I have the same volumes (100L + 35L) as you. I installed the ViaAqua-475A with a flow rate of 2000L/h. It raises water by 1.2m, and I placed a large rain bar in the aquarium. There are no storms, but there is also no need for additional circulation pumps (there is intense flow in every corner). You can reduce the flow; the pump has a regulator, but I am satisfied for now. Go for 1200 - 1800L/h.

Jason

The funny thing is that I want to direct the outlet from the return to the stones, and it will be yet another circulation pump.

I have 1800 for 240 liters. I need it to be 2.5 times less.

Stuart

Well, 2.5 times is 700 liters, the chudor will handle the height, unfortunately, there is no atman, and the hibasho starts from 1100, and just a bit more power will provide a wave in addition to the circulation pump.

thank you to everyone who responded to this issue!!!!

The PH-2000 for the 180+80 system is indeed quite noisy, but in my case, it's not critical. The lift is 1m. The equipment of the PH differs from the AD - the PH has a richer set (valve, elbow, adapters, nozzles). If I'm not mistaken, all PH models come with ceramic shafts.

Mary

The aquarium ordered is 50/45/45, the sump will be 40 liters for now, I will see and consult, maybe I will have to glue a bigger one. Since your system is twice as large, I think 1100 will definitely be enough. If it's not enough, then I will use it for the skimmer, and I will provide a more powerful one for the return.

Elizabeth6302

In terms of volume, your system is similar to mine. I have an Eheim 2000+. I maintain the circulation at a level of 600-700 liters per hour (I measure the filling of a 1-liter aquarium with a stopwatch). The height of the lift is about 1.2 meters. I have a power reserve since the pump is adjustable. The performance characteristics of the pump decrease over time (due to pipe fouling, changes in the magnetic characteristics of the rotor, etc.). It's important to have a reserve. I think the RN-1100 is insufficient. Additionally, one must consider the water consumption of the skimmer. In other words, the skimmer's water consumption should be comparable to the water turnover in the system.

Additional aeration for aquariums will not be needed!
