Carbonating Stone with 1/4" Barb, 0.5 micron

Works great in conjunction with the Eagle Brewing FE378 Oxygen Regulator  Eagle Brewing FE378 Oxygen Regulator for Disposable Tanks with Barb . I made a wand using some 1/4" ID PVC and a double 1/4" hose barb. Get the O2 from Orange or Blue big box store, and oxygenate your wort for about 60 seconds. Really makes a big difference in how well the yeasties in the primary takes off. It sure beats "rocking the baby" to aerate the wort in the fermentor.

I use the stone for oxygenating wort and carbonating beer. I tossed between the 0.5 and the 2.0 micron versions. When I first attempted to use it, I thought it was defective being I could not blow through it. However, when the question was asked to the community, I learned that pressurized gas needs to flow through it. When I force-carb my batches, I connect the stone to 1/4" tubing and then to the liquid line for most kegs (some have a stem on the gas end). It produces very fine bubbles and reduces carb time dramatically. For the wort aeration, I connect a small O2 tank to 1/4" tubing and let it run for 60 seconds.I would recommend that the sellers include a free clamp with the stone but I don't that should be a deal breaker either. I love the stone and considering grabbing another!

I accidentally ordered the 0.5 micron stone instead of the 2 micron. I wanted to use this to aerate my wort with a fish tank air pump, but it could not push air through this stone. I cannot give it a bad review because it's my fault. I just want to warn others who want to do this that they should get the 2 micron instead! This can only be used with O2 or CO2.

I'm impressed with the quality of the stone but it requires too much pressure to get adequate aeration for my fish tank. I may try a slightly more course stone - my theory is the stainless steel will outlast the traditional air stones.

Works well, but needs higher pressures (>5PSI) to work well. Also, I've noticed a few of thse starting to rust after just a few days of use...

Could not use it for oil filtering. The holes are too fine. I am sure it's great for it's intended use , though.

Great for carbonating and oxygenating. I like these better than the .2 um due to these being more prone to clogging than the .5 um units. Get some 3/16" ID silicone tubing, and is a perfect snug fit, not needing any wire or clamps to keep on the stone. This unit with the silicone tubing can be immersed in boiling water to sanitize/clean, just get a small tip baster to drive some of the boiling water into the tubing, so it purges any wort out of the stone. Another tip is to keep your oxygen flowing while in the wort, even when done oxygenating/carbing. This will minimize amounts of wort getting into the stone from the wort's head pressure. then keep it in Star San so you have a sanitized stone whenever you need it. Also never clean stainless with bleach, as the sodium hypochlorite is reactive with stainless and will degrade it over time.

I homebrew very frequently and use 5 Gallon Cornelius kegs to carbonate/dispense. I purchased two of these carbonating stones to increase my carbonating process and have been very pleased. It just makes sense that running CO2 through a stone at the bottom of the keg and letting the tiny CO2 bubbles work their way up through the beer is a better idea than "pushing" the CO2 into the beer from the top. I have read were others say that the beer can be fully carbonated within 12 hours, though that has not been my experience. I connect the stone, set the regulator to 8-10 PSI and in a few days, have perfectly carbonated beer. My experience is that the stone takes off a good 3-4 days in the carbonating process which is well worth it for a couple of dollars.
