## Questions & Answers

**Q: Is this “new version” the one you can bend yourself?**
A: This is the new version (Special) however this is NOT the extended version (the one you bend yourself) 
This unit is about 6 inches in length comes with 2 x suction cups and 1 x Plastic U bend

I believe the one you are looking for is the Special Extended (about 15 inches long) that can be heat bonded over the rim of your tank.

**Q: Can this be used with diy citric acid/baking soda co2, or does it need high pressure?**
A: It it helps, I’m using it with DIY yeast CO2 and it’s doing a great job.

**Q: Will this work at 15 psi? i have an older low pressure regulator.**
A: This is designed to work with DIY Co2 systems in mind so you should not have any problems running it

**Q: Would the small size work for a 5 gallon fluval spec V?  Thanks!**
A: Yes it would be a good size for a 5 gallon tank.

Thanks
