So I a contemplating on buying an MP40w for my 90g. I currently have 2 koralia 3's. I don't have many corals at the moment, but am doing some upgrades and plan on adding Lps and SPS down the road. Will one unit suffice along with the 2 koralias? Can't spend the money on 2.

Let me know your thoughs? Do I even keep the koralias in the tank? I was thinking if putting them in the back. But then will they disrupt with the different wave settings that the vortech offers?

I have 1 mp40 in my 75gal. It delivers good flow for about 2/3 of the tank. The final 1/3 receives very gentle flow, so I stuck my 'nems and hammers over there. I want an mp10 for that side though, I'm sure it's creating a nice big dead spot.

One would be fine if you have other pumps to back it up. The other thing you could do is buy two mp10s for the same price.

Interesting point. What would be a better option…2 10s or one 40???

I would say 2 mp10s but if you bought 1 mp40, then down the road save some more money and buy another mp40. With the mp10s you really can't do that.

I have a 75G and originally bought one mp40 and felt the same way regarding flow...I did add an mp10 for the other side as I wanted to more flow for my SPS on the other side...Really depends on what type of corals you are planning to keep...

I have only One mp40 in my 120.. believe me i tried two mp10s and the do NOT move as much water as one mp40..

The one will work.. if you are worried about the far end then get a smaller pump like a koralia... I use my return on that side and everything is happy with the flow.

The more coral and rock you have, the more flow you'll need. I ran two small Rio's at the back and one MP40 at the front on our 90G as our tank was packed with coral. I never worried about disrupting a pre determined flow patern set forth by the MP40.

All depends on your tank and what you have in them. I am running three MP40WES in my 150g. One on each side and one at the back wall facing forward. I have lots of large SPS that block flow. Thinking of putting another in the back wall to help.

It all depends on how much rock work you have and the placement of the rock. Also the kind of livestock you want to keep. Every setup is different than the next. Right now one mp40 and the 2 koralia 3's should put out a good amount of flow and later on you could add a mp10 or another mp40 I have one in my 90. The other end is covered by the return everything in the tank seems to like the flow. I keep LPS/SPS/clams and softies in mine and I don't think there is any real dead spots to speak of in mine.
