Thinking out loud!

The current is always purely individual! Everything needs to be taken into account: how the stones and corals are positioned, the size of the aquarium, after all...

Pay attention to Aquael pumps, very much...

Two pumps of 900 l/h for a 128-liter aquarium is quite normal. The pumps are most likely Hydor Koralia Nano, the ones from the Kharkiv store.

Yes, it's this pump! But I have doubts because some people have two 3000 liters per hour in their aquariums like mine.
