I am new to hydro and have another question for you experts. I Am using a bubbler system made out of an 10 gallon aquariumn. Im growing two plants with one large air stone undeneath the netpots filled with hydro rocks. I heard that the airstone does not provide a great deal of o2 to the water so i was wondering if my water fall style aquaruim pump would add alot more o2 being that the water hits the air before dropping into the res. . I also was considering an NFT conversion using the water fall style pump and some square pvc pipe. any suggestions would be greatl appreciated.
thank You

The following may help increase dissolved oxygen:

Your waterfall pump.
If using a water pump, a venturi tube.
The longer the oxygen bubble is in water the greater the dissolved oxygen. A deep reservoir will help do this. However, this depends on whether your pump has enough draw for a deep reservoir.
Hydrogen peroxide.
If you are going with a NFT system flow rate & system slope affects root 02. Steeper slopes & a faster flow rates are recommended. There is a bit of information on this page:

Go to:

The Sri Lanka Agriculture site has some interesting info on NFT slopes:

Key word slope:

"The maximum length of the channel is 5-10 m and is placed at a slope drop of 1 in 50 to 1 in 75." (1m is about 1 yard).
