I think you will be happy with the tunzes
This morning will be spent testing out these two power heads to see how they compare to gyres which I’ll be using to keep detritus from settling in the bottom and ecotech powerheads. I use ecotechs on my home system, but find the wet sides to not be very reliable. They’re hard to place perfect without vibration. If the move the dry side dropping could be very expensive and the wet sides need replacing every year or two from the magnets going bad.
While expensive I’m hoping the stream 3 is a good option for random flow. The 5 year warranty is the longest in the industry and should pay for itself if there are any issues.
They have a much wider flow pattern then the vortechs and are very directional. No as much across the tank power with the wide flow nozzle but move some good water. I have 2 6095 and 1 6125 on the back glass with wide angle nozzles and 2 mP40S on sides for undercurrent up front it works quite well I think with the combination you'll be happy!
