I currently have 1 Vortech QD MP60, 1 Tunze 6105 and 1 Tunze 6095 to provide flow in my 125 g SPS tank. The MP 60 is placed in one of the sides and the two Tunzes are located across the tank, flanking the overflow.
This original disposition was fine some time ago, but corals have grown and while the MP60 keeps delivering a huge flow at the rigth side of the aquarium the flow at the other side is quite reduced due to coral growth, the rock disposition and the narrow flow delivered by the Tunze pumps. I'm thinking about replacing one or the two Tunzes for a wider and higher flow alternative. Alternatives:
1. Add two MP40 at each side of the overflow. The Vortech pumps are great in terms of flow and easy maintenance but pose two problems. First, as the flow can not be directed I should buy two MP40 to place one at each side of the overflow, which represents a very expensive alternative. Two, and more important, they are not silent as the Tunze.
2. Change the Tunze 6095 for another Tunze 6105. That would improve the flow in the area where the 6095 is placed now, but would not solve the flow problems in the 6105 area (although I could place the 6105 in the upper position and the 6095 in a lower position; not very aesthetically pleasant, however)
3. Replace one of the Tunze for a wider flow pump that can be oriented to some areas of the tank. Here is where the Octo Pulse 4 pump could be a good alternative. However, it should be as quiet as the Tunze 6105.
Any thought on these? I would like to hear opinions from people that have run both the Octo Pulse and the Tunze pumps and may compare them in terms of noise.
