If you're gonna run when not home only just remove any air stones and use open lines. They are noisier but definitely more effective at raising DO than using the same equipment with stones. If you make the hole in the tube place it so that the resultant jet is really agitating the surface. This will raise DO fast and the water/solution holds onto DO for an extended period. Considering you'll be bubbling for half the day and then relying on the fill/drain and possibly the water jet I'd bet money your DO level will not fluctuate.kenned said:Thanks for the replies..
I think I'm going to start with just using the air pump when I'm not home, and also having the hose short enough to make the water splash..
If that doesnt work, I might try to make a hole in the tube so that splashes also..
Lets see...

BUT after reading this thread, my thoughts begin to lead in the direction of having airstones in the TRAY which only turn on with the flood.
this would provide the 'DO' needed in the flood times where 'DO' is the lowest.
right? the only reason with this in mind to have a air stone in a res, would b to keep it circulated (prevent algae, and keep nutes mixed).
you got it going on...statictattoo said:Meh maybe Im wrong on this one, the guy was saying he wanted something quiet so his gf wouldnt complain... I don't use airstones my plants seems fine, and yes having that hole in my intake line mixes AND airrates.. but that is also my flowering REZ
Heres a picture of my veg rez
All it has is a short drain pipe, but yes i stand corrected my friend the airstone ph comment is not from personal experience but from something i read, thus I am probably wrong... but all I'm trying to say is you don't need a airstone.. and you don't cause I don't have one.. but everyones grows are different
Haps said:Bad advice times two, so far. DO is life or death for the girls. You can probably get by without air, but you will have less vigor if you slip below max do. I put air into all reses, and all buckets, and my girls are happy. DO your girls deserve to be all they can be, or is good enough good enough for you?

Haps said:I only know what I have seen work and not work, and concede that my systems are overkill. But DO is important, kinesis in water is the difference in good water and bad water. When you have seen enough failure, you learn to try to avoid it. Here, yes I believe a waterfall can give you enough, but will it be enough if your temps go up two degrees? How long will your girls survive if your pump fails? Is there a point of failure?
There is no one right way, I only know what I see.
