So,...Tom,...does this mean that we :
1). should still go for a wide shallow tank
2). maintain just a mild to moderate flow in the tank like a pump rated 5-8 times the tank volume per hour (i.e. not 10 times the tank volume turn over rate)
3) make sure that the surface ripple is kept at a minimum
4) Ensure proper distribution of flow throughout the tank (i.e. spraybar along the back glass of the tank / strategically placed lily pipes etc?
5) We can still use the trickle filter to enhance the gaseous exchange ability provided by the shallow tank?
I really want to give this idea a shot y'know?. I've already ordered for a tank 36 inches long, 22 inches deep , 15.5 inches in height
. I sort of calculated the surface area per volume ratio (S.A.P.V.R) of Alastair's puddle & these figures brings me close that .....probably off by 0.01 or so I think.
