Probably depends how visible the spray bar would be. I use transparent acrylic, close to the water surface, and when kept free of algae it is hardly visible. It can give a good surface agitation and water movement over full tank length for gas exchange (oxygenation, CO2 stabilisation), distribution of nutrients and CO2 to plants, while avoiding local high flow areas that could be an attractive home for BBA . When the water circles back via the bottom layers, then upwards at the back, it may help keeping stem plants steady in place.Hello all. After thinking and reading. It seems it would be best to have the flow back from the sump be a spray bar?
What or flow pattern? Im thinking circular from the back to front.
Thoughts?
It probably also depends on the (hard-)scape in the tank? A lily pipe may work best with some scapes, and it looks great.
