Do i need to bubble my mixture?

[967]

Setting up auto DTW, pump has been tee'd off so the majority of water circulates out of the tee. Pump will only be on a matter of minutes twice a day so would only be circulating as long as the pump is on

I know bubbling it will oxygenate, but will also cause ph to constantly rise? Was just gonna have drip lines elevated a few inches above pot to oxygenate some on the way down

This sound acceptable or is a bubbler recommended?

I use a circulation pump that runs all the time.

Argh, can't afford to get another pump at the moment, spent a lot on my grow as of late. Can get hold of an air pump for free, but its a bit of a beast and i'm worried about the noise. Will be running pump for several minutes twice a day to start with and upping that to 3 - 5 times a day further in the grow. Would that be enough circulation?

Pour and stir will yield great result's.Just stir now and then.
