## Questions & Answers

**Q: I see only a single large bubble coming out of the diffuser.  Not seeing the fine bubbles.  What am I doing wrong?**
A: We're sorry some of the diffusers did not work well. But now the problem has been solved and each one is tested before shipped out. 
Anybody who has this trouble, please try to tighten the cover of the diffuser by using the anti-slip rubber ring, or contact us for a free diffuser replacement.
Thanks for choosing our product!

**Q: Hi ,can I double the amount of citric acid, baking soda and water to get a lil more pressure?**
A: The instructions both on cylinder and book say not to. The cylinder is about as durable as a double walled thermos I wouldn’t trust this to hold more pressure then they claim it’s designed for.

**Q: How many bubbles per min for plants in a 4x4 grow tent?**
A: I tried this in 3x4 and it barely made any difference in co2 ppm. Even at probably 1000 bubbles per min, it was out of pressure in less than 2 days.  I would say this would never be enough for a 4x4.

**Q: Can I purchase a replacement valve and regulator? If not what size is the threading? Will cga320 fit?”**
A: I looked into  it and just bought  whole another unit . But you can . Go to there website. You have to b real careful with the clip from the power cord it breaks easy .
