Hey people,
I'm sick to death of the noise of the 80 litres p/m air pump noise and cleaning the diffusion rings so I was thinking of going down the Venturi route.
I currently use 6 or 8 40-litre/9-gallon buckets/pots with the same size control/header tank. I was thinking of getting larger pots/buckets which are more rectangular in shape and the Venturi valve goes on one side so it has longer too (shoot). I was thinking maybe 65-litre/15-gallon rectangular buckets with a second header/control tank outside the tent which would be connected to the system from the main header so the water pump has its own tank/pot (there is too much going on in the control/header tank already due to the probes etc. I guess if I removed the normal water pump there might be room, it just depends on the physical size of the pump, I also thought more water so less heat buildup and the water tank with the pump would be on its own.
Can anyone let me know what they think about the design and also recommendations on water pump size for 4 or 6 x 65 litres plus a header/control tank of 40 litres (total system volume is around 440 litres or 96 gallons? The diagram attached is without the extra tank and only 4 pots as with the original water pump taken out it should fit fine.
In the diagram, the pumped water for Venturi is a lighter blue colour and return is the dark blue. The black square above the header/control is the water chiller and inside the header/control is the water pump. There are quite a few things missing like my filter on the return line etc.
The questions I have are, does it look ok in the diagram? Do the pumped water lines for the Venturi have to be equal in length to the pump? If so how would I add two more pots?
What would be the required water pump for this setup is the attached setup with 65-litre/15-gallon pots to give enough pressure for 4 Venturi valves?
If I was to add two more 64-litre pots then what size for that and also the best way to attach them while keeping the water lines the same length (if needed). I could install two water pumps going to the same line and reduce the intake of both for redundancy maybe?
Cheers
