follow the directions

Comments: This is a great pump, but follow the directions. Make sure it is above the water level. I had it below and it flooded.
So this is my second one.
Also, if the pumps seems to stop working when you are using it for a calcium reactor, make sure you check your tubing first before you replace any pump parts.
Just some info from my own experience.
I would suggest this pump for calcium reactor over a small air pump. I think it works better and is more reliable.

Comments: This is my second pump for another ATO application. The first pump has been running flawlessly for about 1 and 1/2 years now. And the second one has set-up the same and it also is running flawlessly.
In response to the problems noted in other reviews, I think that the instructions (or lack thereof) leave a lot to be desired. If the instructions were a bit more explicit as to greasing and assembly, I'm sure people would have better results.

Comments: best little pump out there! simply plug and play. I have looked all over the internet, and locally (hospital) for a peristaltic pump for my calcium reactor - this is perfect and relatively inexpensive. why did I wait so long to buy it??

Comments: This is an excellent unit. Has been very reliable for over a year running 4 hrs every 24 hrs for automatic top off throuth a kalc reactor. The roller assembly finally cracked. Replaced it and im back in business. I am very pleased with this unit. The float switch is very precise once set properly and reliability has been excellent.
Didn't do the job for me

Comments: I bought this pump for an auto-top-off system which is run through a Kalk reactor. It worked very well at first, topping my sump off at a very slow rate with saturated kalkwasser. The problem arose when it started siphoning kalkwasser back into my freshwater reservoir after shutting off. This quickly clogged the airline tubing connected to the pump with calcium oxide. Because the pump does not develop very much pressure to begin with, it failed and required constant cleaning. I would not recommend this product for top-off systems run through a Kalk reactor.
