Hi All,
I have a cheap 4 head jebao doser for about a year now. The peristalic seal from the silicone tube isn't perfect so if you put the dosing bottle either too high or too low, the other end would either slowly drip out or recede back up the tube. In the beginning, the seal was good enough that if I get the dosing bottle at just the right height, it isn't that big of a deal and I was able to dial the dosage in correctly to more or less maintain stability.
However, this past month I've been busy with a newborn baby so didn't check for 4 weeks until this past weekend. To my shock, my alk, which is typically maintained at 10, was at 6. The dosing bottle didn't run out, and the doser still worked, so the only thing that appears to be causing this was that the silicone tube was worn out that it couldn't hold the seal so the liquid was receding back really fast and have a lot of air bubbles, which resulted on a lot of "dry pumps" and under dosing.
Now, I'm thinking about if I should bite the bullet and get a more expensive doser but before I do, I want to hear some of your experiences:
1) with the more expensive ones, like the neptune, for ex, does the peristalic seal hold the liquid in place?
2) does the tube get worn out too or can it hold the seal long term (like years)
3) if high end ones like neptune still wears out the tube then maybe ill just consider replacing the silicone tube on the jebao instead.
Thank you in advance.
