best air stones for DWC systems?


Recommended Posts

Riteo found u can get these kind of air stones that produce fine air bubbles just like the o2 grow units....a lot cheaper....

There call diffusers

Does anyone use these?

 

I'm wondering if my 10 way aquaone high volume air pump would run 4-5 of these?

 

Here is a link to my air pump I'm wondering if it will have enough pressure? https://www.eppinghydroponics.com.au/pond-one-o2-plus-4000-air-pump-10-outlet-p208.html

 

I have a feeling these need more pressure behind them to run yeah? Too much makes them woek like regular air stones which I do not want...

 

Iv seen a diagram were these four point diffusers are hooked up to a oxygen tank with a pressure valve so this has me also thinks Ng they may require high pressure? Any help would be great as I'm looking to buy these.....cheers

haven't run a dwc system for a while, but when I did, I used these airstones  ... fairly priced, good quality and weighted - they stay on the bottom of the res.

I actually ran a fair few of these off a nice quiet pump ... the Techno Takatsuki Hiblow HP-100. If I was to do it again though, I'd go with a slightly smaller and cheaper pump - Thomas LP-80HN. If looking at getting a good pump ... look at sewerage system businesses - the ones that install in rural areas. They are usually way cheaper to buy than from aquaculture, hydro or fish shops. Also ... spend the money on getting a good 8 (or more) gauge manifold a ball valve and also a pressure gauge.
