Good to hear.
The size change is mostly to make it fit in the sump. But from pictures, my growth is not as long,
so pretty clearly over-sized.
I do hope to eliminate the diffusion grid. I am pretty sure I am losing a fair bit of light in that.
I did not mention flow, but largely because it will be adjustable.
The max flow is the entire tank drain, which is from dual Pan world 50PX-X, with about 4 feet of
head = roughly 1400 GPH.
At a 16 inch width, that is 90 GPH/inch.
But I will have a bypass valve, plus I can limit it with slot width.
