I recently bought 2 maxspect gyres F350s.
My tank is 5ft and 550 litres in total. But I feel the gyres aren’t strong enough surface movement is minimal? I’ve tried them at 100% still don’t seem right currently using the table below but 20% higher at each stage.
Any ideas? If the flow looks fine or should be fine?
