This is the GH air pump I use for my Waterfarm grows… Seems my drip rings clog less when I filtered the air… This is a simple add on to the GH air pump…A little 2 sided tape and it’s done… There’s no back pressure with this filter, no strain on the pump… This is after 3-4 grows…
interesting, I thought it was biological growth that would be blocking the stones… 
Don’t know about air stones, but dirty air does seem to contribute to the clogging of my drip rings… I figure there’s lots of things in the air looking for a water home… I don’t use any air stones… Really don’t know what it is that builds up on air stones… I’d suspect it’s from a reaction between the air and water…
The constant drip of water on 9 liters of hydroton supplies all the DO that’s needed by a pot plant at all stages of growth. My plants are proof of success without the use of air stones, anywhere… The only added source of heat this type system generates is from the drip ring… I’m hopeful, We’ll see…

can you take some photos and explain a bit, do u find the hydroton acts as a biological filter…? 
, interesting stuff buddy…, how do u get the constant drip? thanks…

It’s an ebb and flow system…
Just sounds like a constant feed/water situation…
Pics of system would help…
Old school grower on here , was killing it with his own take on ebb and flow…
Trust me , more oxygen = more fruits …
It’s a fine line tho when it comes to thirsty plants…
That’s why I run rdwc systems… no worries on plant’s going dry , but I love the growth rate of ebb and flow systems , I just cant afford a power outage for 20 hours and have to hand water 20 plants every 3 hours…

That would suck.
I am amazed at the variants on hydroponic systems every time. I’m really looking forward to our move to Colorado next year as I see straight RDWC there. But @Bogleg does a wicked flow table too haha.,

There’s a misunderstanding here and it’s mine, an assumption on my part. My second post shows’ the mod to a regular WF that turns it into a rdwc setup… The white thin wall pvc is connected, by tubing, to the reservoir. The waterfarm dripring drops in the pvc column… As the water is pumped out by the dripring, the column is replenished from the reservoir by gravity… The sight tube location is now the return line to the reservoir, also by gravity… recirculating 5-6 gal an hour… Not much compared to elect water pumps… More than enough for a water farm…

No worries my friend… lol
It’s an ebb and flow system … it’s just either a constant feed or on a timer and should still be sitting in a few gallons of water just to make sure that it don’t go dry…

@idkonk where did you get the square buckets?
Cat litter buckets are square

Mine are current culture brand but I’ve seen a few others out there.

The sq ones with the little door on top look cool.
Yeah but they aren’t black would really prefer black plastic instead of covering/painting it.
edit: removed inflammatory statement
The black abs 1-3/4" washers you see on the outside of the reservoir serve two purposes… First to spread the force on the rather thin skin found on most ice chests and the Igloos … Second is as spacers to compensate for the not perfect length fit of the 3" and 6" cut off sprinkler risers I use… This works because there are no rubber washers on the outside of the ice chest… I use Teflon tape where it’s needed.
I’ll post more pics and try and cover as many of the details as I can… I bought the 13/16" deep hole drill off Amazon, 6-7$, It was needed to get a clean, straight hole through the ice chest and Igloo insulation… It also works for the center hole in the washer/spacer… A 13/16 spade drill will work for buckets when drilling holes for 1/2" grommets. The old 1-3/4" hole drill I had on hand… The plastic washers used on the outside of the igloos are cut from 5 gal buckets… I also had 1/4" and 1/8" abs sheet on hand from other projects.
Plastic washers for the outside of an igloos, I cut from the sides of 5 gal buckets… Almost all the parts I use, or adapt, are bought off the shelf from HD…
Please bear with me as I go through this again, The pvc standing water column connected to the reservoir is what makes this setup work… The water in the grow igloo, and the reservoir, and the water column are all the same level… The drip ring will remove 5-6 gal an hour from the water column, which is then replaced from the reservoir at the s`… With the dripring adding 5-6 gal an hour to the grow Igloo, gravity will return the water, at the same rate, to the reservoir near the Ice Probe… We’ll call this my Waterloo…
When drilling the plastic washers/spacers, I drill the pilot with 13/16" drill, but not the hole itself… That holes serves as the start hole for the 1-1/2 hole drill… I drill out the 13/16 hole while holding the 1-1/2" plastic in a $2.99 clamp from HF…

Is this a kind thing to say? Is it helpful?
I would appreciate it if you would edit that into something a little less…confrontational.
Thank you,
Alan

What would you suggest I say… Twice PF has said it’s not what it is… Twice I was not confrontational… Put words in my mouth if you please… After all is said and done, you run the show… It was about as gentle of a backhand as I’ve got… OK we’ll do it you’re way… Please forgive me PF for being so rough on you…

Don’t aim any sarcasm my way, please. You and I both know you could have worded that better. @dbrn32 @MattyBear @garrigan62

So it seems like this is similar to the way a toilet works if it had the handle down all the time.
