question about air disc

in the product description for the air disc it says you need a air pump that does 10L of air a minute. if i wanted to run 6 of them would i need a pump that does 60L a minute? or would 30L do it? thanks.

Uh oh. You are going to have troubles if you dont know basic math. That would be half of what is required.

math is not the problem, in the product description all it says is you need an air pump that does 10L. it doesn't say anything about using multiple discs. i'm guessing i'll need a 60L pump then. so whats the most quiet 60L air pump?

thanks for the help iamaaror

I would strongly advise against the air disc. I bought five, had hard pipe going to them and a pump big enough to drive them all. Hooked it all up...fuck me, really? Weak sauce for sure. If you want top of the line stones that never clog then grab some alita sintered air stones.

They are not cheap but they are money!! Ps. You don't need much air going into the Rez to keep it at maximum saturation. I tested it once.

cheers guys, i'll have a look at those.

Sun leaves will clog. Almost all stones clog..except the alita.

To clean stones. Let them dry out. Then boil them. Then let them dry again

I don't think you even need air stones... some people just put the air hose in the bucket/res. They do make convenient weights though.

So you don't run airstones?

no I do

Well, congrats for adding to the confusion. I've actually never heard of people just using hose.

I'm sorry you are easily confused.

Just kidding, I don't give a shit.

The best air disc available on planet earth is the 8" diameter aluminum oxide airstone. It's a blue colored air disc like all the others , but of all the round air discs this size is the only one made with aluminum oxide. It cannot disintegrate over time and is easily cleaned by drying it out and immersing in a dilute acid (hardware store 31.45% muriatic acid [HCl] watered down 6:1 to get it around 5% HCl). The maximum output of this airstone is 20L/min but it is not necessary or advisable to run at full blast because excess pressure will crack the black ABS bottom casing, so a 3/8" or 1/2" pvc ball valve online with the hose can reduce the airflow to safe levels. The most efficient pump/ stone combination is achieved with a Danner Pondmaster AP-100 (6.53cfm) and 12 discs valved accordingly so that the stones output is at 75% of the max. The replacement diaphragms for the pump are about $10 and the stones can be placed as low as 10 feet below the water surface with this pump, but of course the lower you put your stones below the surface, the more back pressure you will give the diaphragm resulting in less stones being capable of delivering air (the diaphragm will have to be replaced in a much shorter time interval if stressed to the max) to the water columns. The reason why I like this stone the best is because of the 8" diameter footprint. It achieves the most surface agitation of any other stone. It's the agitation at the surface that counts and not neccessarily the amount of air output of the stone that counts. As the air travels up from the stone it pulls water and air down toward the bottom of the water column.

+1 for the pondmaster Ap-100 I have three of those bad boys and they are fucking awesome!!!

I use a 112 liters per minute pump, what is the average most people use?

minimum 1L per gallon is the recommendation I have seen. Anything like 60-80L should be good for most traditional dwc setups.
