Review: Works well as automatic liquid chlorine dispenser - I used this for a homemade automatic liquid chlorine dispenser for my pool. I travel a lot, so I'm not always home to consistently add liquid chlorine into my pool, this works perfectly, but you need to frankenstein it a bit. In case anyone is wondering how my setup works: I bought this, a medium sized ammo box (although a small one would probably work too, I just wanted extra space), a 3mm ID x 5mm OD silicone tube, I already had a long outdoor extension cord, and some kind of timer (can be christmas light timer or something. although a timer with short time increments would be the best, like minutes if possible). You just need to connect the silicone tubes into the nipples that are already on the pump. You don't need to do anything to the pump. Then you just plug everything in, connect one end of the tube into a bottle of liquid chlorine and the other end straight into the pool. Set up the timer and leave it alone. That's it! The quality of the pump is fine, I haven't had it long so hopefully it works for a while. It's not noisy at all. The default power is more than enough for my use, I actually have the dial set to about 25%, it was pumping way too much at 50%+.
Review: Saves time & less spills for aquarium work - Simple to snap the pump onto the housing for first time use. Connect two pieces of your airline tubing to the pump and plug it in-you're done. Purchased to acclimate new aquarium fish from the store water to the quarantine tank water at home. It was self-priming and pumped like a charm. Very satisfied.

### ⭐⭐⭐⭐⭐ Works well as automatic liquid chlorine dispenser

### ⭐⭐⭐⭐ Great for home tech projects
*by W***4 on January 3, 2022*

Update: I did have one pump exhibit the black residue some have mentioned and it began slipping. I took a jewelers file to the motor shaft and roughed it a bit to help it get some grip again. The other 3 have been well.. but they only get used half as much as the pump for detergent. Bought this set to make a home laundry detergent/additive metering device. Having used one at work, I priced the commercial units and the prices were unreal. The pumps do not move a large amount in a short time.. which in a home environment.. is a good thing..(users less likely to hit the button again to pump more!) Each pump delivers at a slightly smaller/larger volume with the same voltage.. I used a 12v 1amp power block along with smart switch that only allow one pump to run at a time. The pump delivers about the recommended amount of detergent 1/2 cup, in about 2 minutes. After designing the unit I discovered that we, like most use to much of all the laundry detergents/additives.. So this pumps have ALREADY paid for itself in saving on the chemicals. Other users have noted debris and other issues with the pump, however I have not noticed any abnormal/discolored debris in the pumps; I have had them apart 2x to check. But it should be noted my pumps only get used about once a day, 2-3 days during the week for detergent.
