good luck 
Roger

**Q: How powerful does the pump need to be for this air stone? All the bubbles aren’t coming out of mine and I suspect it’s because the pump right. Thanks**
A: Did you set the stone in boiling water first?

What I did is put the stones in boiling hot water, and just left it overnight to help it become more porous. If you've already put them into your tank, I'd try boiling them for 10 mins or just leave it in hot water for couple hours

**Q: Do you have to poke holes in it for the air to go through?**
A: No it's porous so the air just passes through it.

**Q: Is it ok for koi pond**
A: It's rubbish, don't waste your money.
