well i went 3 minutes this time . Stainless Steel stone seems to be clogged. I soak it before and after use in Starstan solution and take care not to touch the stone, it has set for six months. Any recommendations on cleaning the Stone?

I think a good soak in hot PBW or similar alkaline cleaner would do the trick.

My stone came with instructions to boil it in water for 10min to remove any gunk that builds up in it. It also sanitizes it.

I boil my stone prior to every use to sanitize it. The stone is porous and can harbor bugs. I don't trust just using a sanitizer.

So, curious to know what the consensus is... on this thread everyone is saying keep it under 2 mins. I did a search under 'aeration' and other threads suggest going as high as 20 mins with an aqua pump and stone...

Confused! I too after say 2 minutes will start to get foam going all over the place...

aeration and adding pure O2 are two different things. When you use air pump you are only putting a small amount of O2 in because air has other gasses.

Now when you hook the stone to an o2 tank and let her rip you are infusing pure O2

If you're using an aqua pump and stone, you don't have an O2 system. You're pumping regular air (like, the stuff around us that we breath). That's about 80% nitrogen and 20% oxygen*.

It's going to take a lot longer to aerate with that sort of setup than with an oxygen system.



*Technically it's more like 78% N2, 21% O2, almost 1% argon, and some CO2 and trace amounts of other stuff

Ah, clearly you guys are dealing with a rookie here!

So... using the aqua pump, how do you prevent the foam from going all over the place?
