Another day, another different fight to pick. This time BGA. I don't like the rate of flow coming through my lily pipes, they seem to skim the surface well enough but it doesn't reach to the end of the tank, and definitely not the bottom. Tried adding a stream pump but that seemed to cause the inhabitants of the tank to be caught in a whirlpool storm. so decided to just pop the spray bar back. At least I know that one shoot to the end and bottom (I position it to shoot down diagonally) of the tank decently. we'll see if that slows them down enough.
