## Questions & Answers

**Q: How do i get a 20mm replacement nozzle for this pump ?**
A: I have been trying to reach this seller for quite some time now without any success.  I have used the email address on the box as well as tried messaging them here.... no luck

**Q: How do i set this product to be on a steady flow. The manual isn't clear.**
A: If you press the mode button it switches between 3 digit numbers starting with a 1 or a 2. anything starting with 1 is steady flow. If you decide to use wave mode though the number preceded by 1 also affects wave mode. The number preceded by 1  appears to affect duration of the pulse where as the number preceded by 2 affects the time between pulses if the fist number is set to high the pump runs continuously regardless because the cycle doesn't end before the second begins. So long story short if I set the first setting to 101-104 then set the second number to 209-210 my tank really rocks and roles. Timing and duration are key to getting a wave going.

**Q: Can I use this pump externally?**
A: Yes and No.  Mine leaked external.  I had to silicone it by unscrewing it and sealing it completely with silicone.  Now it doesn't leak and is external. Caveat Emptor.  But, so far a great pump.

**Q: Is it submsial?**
A: yes, i have 2 of the 18000 models and they are both submerged ...
