Apparently there were some posts on hempcultivation.com about this but that site is down.

Has anyone tried this in a DWC? I have a water pump but it's too powerful for my container and creates a geyser at the surface. I'm going to try splitting the output of the water pump across several points in the container to reduce the amount of pressure going out of each outlet.

[FONT=Arial,Helvetica,Geneva,Swiss,SunSans-Regular][SIZE=-1]Nothing comes close to "flooming" - This requires nothing more than a water-pump which can lay flat on the pond or tank bottom and force water upward to the surface of the vat.

[FONT=Arial,Helvetica,Geneva,Swiss,SunSans-Regular][SIZE=-1]It is not important, or even desirable for the water being "floomed" to break the surface - we DO NOT want a geyser.

[FONT=Arial,Helvetica,Geneva,Swiss,SunSans-Regular][SIZE=-1]Even better, a water pump forces large amounts of water to the surface for gas exchange, and it does so "simply" and very quietly. Flooming is ideal in retailers tanks because, unlike air bubbles, flooming causes less surface distortion so the consumer can still see and buy fish.
[/SIZE][/FONT] [FONT=Arial,Helvetica,Geneva,Swiss,SunSans-Regular][SIZE=-1]A water pump lifts more water than an airstone could EVER lift to the surface for gas exchange.

[FONT=Arial,Helvetica,Geneva,Swiss,SunSans-Regular][SIZE=-1]Almost any brand of pump can work. You will find some pumps "stand up" better than others. It can be disastrous if the pump lays over and stops "flooming" the surface.
[/SIZE][/FONT]
[FONT=Arial,Helvetica,Geneva,Swiss,SunSans-Regular][SIZE=-1]Also, if the pump DOES "geyser" the surface the risk is increased that the pond or vat could be pumped dry by the pump if it directed water over the edge and onto the ground.
[/SIZE][/FONT]
[FONT=Arial,Helvetica,Geneva,Swiss,SunSans-Regular][SIZE=-1]So, a gentle flooming in any tank or vat is superior aeration. And it's as simple as dropping in a submersible pump and aiming it at the heavens. [/SIZE][/FONT]
