so, with a waterfall scrubber all the specifications have been well constrained in regards to screen sizes needed and light intensity & flow over the screen.
But what specs are their for tank turnover rates - the number of times the volume of water in a tank needs to go through a scrubber per hour to effectively control inorganic nitrogen & phosphate build-up over a 24 hour period?
You can have two tanks with very different volumes, but with the same fish populations, using the same size scrubber. Is 0.5 x tank turnover per hour enough? Or is a 3 x tank turnover per hour a minimum?
Seems this aspect has been neglected as I've never seen any information covering it.
