Hello
I'am going to set new marine aquarium 170x60x60 and use there tunze pumps. I want control pumps using Profilux P4.
What type of flow and circulation pumps do you recommend?
Kinda depends. You gonna do lps. Sps. Soft. Mix.
I use tunze I have a 47g aio with one power head putting out 1000gph the other 500gph they alternate with hydor controller. I am guessing with such a big tank you can do 4 power heads 2 on the sides 2 mid back. Not sure power rating you would need on those but having multipul would decrease dead spots
