Hello everyone,
For 90gal I think I need 3 water pumps, two of Koralia 3 and one of the Koralia 2.
Is this correct? I should get stronger pumps or add more pumps?
Is Koralia a good brand to buy or others?
I'm very new to this so any help is greatly appreciated.
Thank you

Depending on what you want to keep, I would consider a couple 4s and a 3. I have two 3s and two 2s in my 46.

Is #4 to powerful? Wow I didn't know that magnum cost 3 times.
Where did you place your #4 and #2?

I'm planning to keep soft and hard corals. 4 pump for 46gal? Then maybe I should get 4 pumps for mine as well.
Do you think two #4 and two #3 too much for 90gal? If no, where I can put the pumps to archive the best water movement?

I'm running 2 #4's and 1 #3 in our 75g reef so it's not too much for 90.
Location:
We have Oceanic RR tank so there is one corner overflow in the upper left hand corner. I have 1 #4 and 1 #3 in the same end. #3 pointing slightly up in the front and the #4 is pointing straight across towards the other #4. That causes a nice turbulence on top of the rock ridge.

I trying to picture in my head and i think I got it. But don't you need to create a flow in a circle?

You should have a flow that is not consistent. It's best for your corals and that way you do get the flow to more places. If your flow is just in one direction, that is how your corals will bend.

You should have a flow that is not consistent, but more like a turbulence. It's best for your corals and that way you do get the flow to more places. If your flow is just in one direction, that is how your corals will bend.

I asked this exact same question about 2 weeks ago and got 10 different answers. I also have a new 90 gal and want some Koralia pumps. Some say 3's are perfect. Some said 3's would be too weak. Some said 4's are too powerful. Some said 4's would be perfect.
All that being said I think im going to go with 2 - 3's and a 2. I'd rather have lower and build up.. I can always buy another pump.. rather than having 4's and everything in my tank being blasted.

Personally I don't think two #4 and two #3 is too much in a 90. If you have corals sensitive to flow you will need to be careful where you place them.
I actually have 6 powerheads in my 46. Two #3 about 6" below the surface blowing at each other from opposite sides of the tank and near the front of the tank. Two #2 are blowing on the back wall at a 30 degree angle and the flow bounces off and collide with each other. Then I have a Seio 810 in the back of the tank blowing toward the front. This causes lots of turbulence with the #3s. Last is a MJ 1200 flowing across the back of the live rock at the bottom. Mine is extreme and not everyone (including me) needs that much flow. It is funny to watch the fish and shrimp try to catch the food if I don't turn the pumps off to feed.

So does the hydor move in different direction automatically?

So you didn’t try it yet? I’m in the same position as you, new and don’t know what to do.

LOL
. I could imaging them trying to catch the food.
That’s a lot of flow you got there. How long did you have that setup for? How are the fish and corals?

I only have a few fish and they don't mind. They find quiet spots in the rocks when they want to rest. The SPS corals love the flow as long as it is not right on them. My hammer and frogspawn are kinda peeved but they deal with it. I have a piece of pulsing pom pom my wife bought and it hates the flow. I will need to move it out or it may not survive.
Another plus is I never get algae film on the glass or do I have any algae in the tank.

Cool! I will buy two of #4 and one #3 for now and I can add another later if the wave is not sufficient.
