How to slow down Osmolator output?

[Jimbo327]

I have a Tunze Osmolator, and it has been working flawlessly on my 6 gallon nano. Now if I am going to add a kalk dispenser, I'm worried that the output may be a little too fast and spike the pH too quickly on such a small volume. Is there a method to slow down the pump? The pump is already operating at 9v.

What if I put a valve on the output of the valve to slow down the flow? Is the back pressure going to do much to the pump? And does the back pressure relieve itself into the reservoir after the pump stops, or does it continue to push water into the tank?

Thanks.

You can use a valve, the mini valves for drip irrigation work well. The pump will be a bit louder from the back pressure.

I might have to try that. I have a 37g and the Kalk Dispensor really raises the pH a lot. I replace about a half gallon of evap a day, and the bulk of the evaporation happens when the light is on. I have since discontinued its use and rely on two part to replenish calcium and alk. My pH stays at a comfortable 8.2 now. Maybe when my calcium demands increase I will start using it again. One note, going through the reactor significantly slows the flow of water.
