Nope they are insulated.

Have a good one, lots to drink, lots to smoke, party favours and lots of sex.... FOTFLOL made you laugh eh! :bigjoint::lol::lol:

The oxygen deficit (D) is the driving force for the establishment of air-water equilibria and is calculated as the departure from saturation: The saturation concentration for oxygen is calculated using Henry's Law and varies with temperature (effect on KH) and PO2, the partial pressure of oxygen.

Area to Volume Ratio The specific interfacial area available for mass transfer (a, m1) is expressed as the ratio of the bubble surface interfacial area (A, m2) to water volume (V, m3), Small bubbles afford greater surface area and lead to more efficient gas transfer, e.g. 1m3 of bubbles...

Oxygen Mass Transfer The rate of oxygen mass transfer , i.e. from the gas (air bubbles) to the liquid phase (water) is governed by the terms described below. Typically, KL and a are combined into an overall mass transfer coefficient (KL a, d-1). KL liquid film transfer...

Mike91 I'm not a weekend grower, I take my growing very serious and go to great lengths to make sure what I do is founded in science and reasearch. Knowing a little about something does not make then an expert, you need to look at the big picture and if smaller bubbles work better than I will...

Impact of bubble and free surface oxygen transfer on diffused aeration systems I supose you think these people don't know what they are talking about? Connie D. DeMoyera, Erica L. Schierholza, John S. Gullivera,*, Steven C. Wilhelmsb a St. Anthony Falls Laboratory, Department of Civil...

you said it yourself "smaller bubbles oxygenate the water better" that's what we have been saying all along, Check Mate, you should let up on the smoke boy, your short term is gone...

You are just so confused, and have no idea what your saying.

the only way I knoe off to get 1/2 is with RDWC.

AS your not getting this right away here is something to think about also. Chiller's are almost 50% more effective at cooling than AC and you can buy an icebox to fit your lights or just blowing in the room to cool it...

I don't agree, that's the purpose of this thread is to see what the difference is. With all that has been said I don't know how you can come to that conclusion? All bubbles are not created equal. As temprature has a direct effect on DO the max depends on temp and avalible oxygen. The fact is...

just google it and pick the one you want Tunnelbear

I don't think it will stand up to a challange but in the mean time they will find a way to hassel us. Like not sending cards out and underfunding the department. That's why it can take forever to get your papers back.

I have tried a similar round air stone and was not to happy with then I still have 3 new ones. May have just been the brand but since I found the fine bubble flexair I'm happy. Always looking for better ways thanks for posting.

Just to be booked, no bail for 21 days, appears to me to be long, but what do I know. I'm just not big on hanging a label on anyone when you don't know the facts and besides he's not the first or last to go down from here.

I'm early because I wanted to be the first one to wish you a happy V day. Peace Kiddo
