air pump for dwc?

what kind of pump would i need for a dwc set up. isnt there a limit to how much you can actually oxygenate water before it is overkill and the oxygen goes right to the top and into the air

All you need is a cheap small air pump with an airstone. It depends on how big the tub is and how many plants. As far as overkill, im sure you could but i doubt you will run into that problem. Basically you want as many bubbles as you can get without making the res overflow. Its very unlikely you get a pump that is too strong.

Alot of people use these types.

the more air the better.

ye i either rock one small airstone for a pot and get a powerful put and split it, or i run one 12' or 14' under two or three pots depending on what you runnin. i once made a a four plant system for a friend which consisted of five gallon buckets, 4 airstones, and an old air pump i had. Just make sure the pump is powerful enough to run all the stones, get some splitters for the tubing, and lots of tubing. I made it so you can move the pots around so you can put them in any grouping. Also, you can use different nutes for different cylces, aka you could run a little sog and harvest every 2 weeks if you do it right. its pretty legit and cheap.

The temperature of your solution dictates how much oxygen it can hold...

The cooler the res, means more dissolved oxygen in your soup...

Very important note Gyspy.

If you can get the water around 68 youll be about max efficiency.

never let your rez get above 75!!!!

thanks for all the input. i think i will post some pics of my aero set up. i think it will be aero dwc hybrid

If you are into contraptions, this is deff. worth the read...

The tetra luft pump from an aquarium supply shop is extremely durable, but since it was a good thing they doubled the price on it in the last few years so I don't know if it is still worth it or not price wise. They used to have a lifetime guarantee on them but they got rid of that also. It used to be a great bargain for $28 with the warranty but I think they are around $60 now. It will last for years and years and I think you can replace every part that is in it. Just a shame when they take a good thing and make a not as good as it was thing.

I checked them out so you don't have to, they are called coralife luft pump and are $65 now. Still get great reviews, one guy said his has been in continual use since 1982 so they are durable. Just when you start getting in that price range I think I'd opt for a piston driven pump.

Active aqua is the way to go, they have a variable air output, multiple air taps, look decent, well worth the price. i also use two flexible airstones. You can also check out hydrofarms industrial air pump its a bit pricier but also alot stronger

i wish there were more books on the subject. do the roots actually use the bubbles? if not then isnt that air that is unused and will dissipate into the air>?

There really isn't much to know, plants need oxygen and water, if you leave theplants in straight water they will drown. The air bubbles create oxygen the plant needs, that way it is getting the best of both worlds at the same time. All the oxygen it needs and all the food it wants, creating an almost optimal growing situation.

If you want more to read just look up hydroponics in general and see how it all works, that should answer any questions you have.
