I've run high tech tanks before and just about to being to an end my low tech puddle, but was just reading on another site and came across this
"The second is increasing turbulence. There are arguments for and against this, but for tanks without CO2, turbulence should increase both oxygen (O2) and CO2 for your plants. Turbulence works by allowing better gas exchange between the air and the water and, as concentrations of CO2 are generally higher in the air than in the water, creating turbulence or adding an airstone will increase the dissolved concentration of CO2. This will also increase dissolved O2, which livestock, bacteria, and plants also require to thrive. It will also prevent CO2 and O2 levels from undergoing excessive fluctuations within the tank due to daily plant cycles of photosynthesis. The only time turbulence will work against you is when you are already using CO2 injection. In that case, increasing turbulence will only work to off-gas this additional CO2."
I was always under the impression in a low tech walsted style tank or Tom Barr non co2 type tank that water disturbance should be pretty much minimal if at all to preserve what little co2 is already in there. I've ensured for the past year my low tech had almost zero water turbulence but if the above statement is true then ill go for this on my second low tech I'm due to start.
Opinions anyone??
