• advice on the circulation pump

  • Derek7322

I rearranged the stones and it turned out that one side has almost no water movement. I want to install a Hydor Koralia 2, 2300 l/h. Do you think it will be enough to create a surface flow if I secure it in the left corner? The width of the aquarium is 150 cm, the depth is 60 cm, and the water level is 80 cm. Is there such a thing in Kyiv?

The Hydor Koralia has a soft, wide flow. For a length of 150 cm, it will be insufficient; expect a normal flow at 50-80 cm.

You can install a regular Chinese pump 1t-2t with a timer, for example, it works for 20 minutes and then is off for 20 minutes... but then it's better to install two (so they blow in different directions), one turns off while the other turns on...

I have an Atman 2.2 in the lower right corner and an Atman 1.5 in the upper right corner, but due to a small grotto I placed, the left side is almost empty. Since the aquarium is open for viewing from the left and front, I don't want to use a large Chinese pump like Atman because it doesn't look very nice. So I'm looking for something smaller, maybe I should get a Hydor Koralia 3, 3200 l/h or a Hydor Koralia 4, 4600 l/h. (I looked at the Resun Waver-15000 WaveMaker for arapaima, but it says it's out of stock), and I'm actually thinking of finding a Tunze; I was told in secret that there will be a very large shipment from this company by the end of January.
