The Reef Royal 220

Chaeto will self-shade itself and drop photosynthesis, so it is not constant. This might help:

"Production within dense mats of the filamentous macroalga Chaetomorpha linum in relation to light and nutrient availability"

Fig 5B shows how, under bright light, chaeto productivity (filtering) drops 72 percent with just 2 cm of chaeto thickness.

Flow drops too.

I am wondering why you did not go with an External overflow box?

The holes were already in the tank. I just made one them bigger for a proper drain. I could have sealed the holes in the bottom and gone with bean animal if that´s what u mean ? But i figured herbie would do fine for my needs.
