I have been researching powerheads from different companies, and I have found the Tunze Turbelle. I am going to get 2 power heads from Tunze. Would you recommend getting 2 Turbelle stream 6125 (3170 gph)? It says it is great for 105g - 528g, but would it still be good to get 2 of those in a 48" long x 24" wide x 20" high 100g tank? I want the 6125 one more than the 6065(1717 gph, recommended 66g - 264g) because I saw the pump and the diameter for the pumps is bigger. Is greater flow better? or is getting 2, 3170 gph too MUCH flow?
