I think we need a bigger pump?
On our nft setup I am running 2 1/4 inch inlets to each channel. That gives good fluid spread in the first 3 or so inches, if I use 1 I don't get good spread for 6 or 8 inches. The problem is when I guessed at the flow rate needed I guessed wrong. When I added the next 3 channels I barely have any pressure from the closest 1/4 inch tube near the pump. The pump flows 900 and some gpm. Seems that there should be plenty to run 15 1/4 in tubes to flood a thin film in the troughs.
I can move the pump closer to that end, it currently pumps up 3 feet and 18 feet around the table. I can move the pump to the other end of the table and the pump would pump up 6 feet and then across the end of the table which is 10 feet.
The pump is rated for 8 or 9 feet I can't remember exactly.
Will that work or do I need a bigger pump?
