Worth it.
(Pardon my mess here.) Best money I have spent thus far. And, I have invested quite a bit. Newish to the hobby. Came back after some odd years. I have three tanks I use this system on, actually, mostly for water changes. This being the largest one. The 20 gallon emergency shrimp tank from the end of year sales on tanks. Needless to say, this little device has worked amazingly. Took a moment to put together, but after that it is quite simple to install. It is totally compatible with average sized hose attachments. Main one being a valve to change how quickly the water is released into the tank. (Important for shrimp keeping.) Drip acclimation is an absolute breeze when you don't have the height to use gravity to drip acclimate. Overall, I am very pleased with it. Couldn't say much for longevity, especially with how I am using it slowing the flow rate like I am, but it's been going strong for a month now and I have used it more than a few times. Would buy another if I ever need to use more than one at a time. (Looking at having a room full of tanks.) ... show more

I never knew how much I wanted/needed one of these until I found this!
I had a friend who had an auto top off system set up on his tank that was plumbed through his attic to a water source in his bathroom. I loved the idea, but was a bit skeptical about the potential for leaks and overflowing if the float system happens to fail. This self contained system is exactly what I was looking for. With a 5 gal bucket under my tank as the water supply, There's no chance for overflow as my 125 gal tank is able to contain that amount without overflowing. I just have to top off the bucket every other day. The only issue I had was due to the thicker tank border that would not allow the mounting bracket to fit without a bit of modification to both the tank and bracket. Once I got the mounting issue corrected, it has worked flawlessly. My water level never drops more than 1/8" below the edge of the tank canopy. Love it!!! ... show more

Reefkeepers: Heads-up! Might not work with RODI! Edit: DO NOT GET. PUMP IS JUST TRASH.
So I spent all day trying to figure out why the pump would only trigger when I was manipulating it with my hands. I was leaning towards some sort of electrical short in the pump. Team troubleshooting discovered there's a low water safety sensor on this model of pump! I don't know if it's on all models of this pump, but there seems to be one on mine! Why does this matter? BECAUSE RODI IS NOT CONDUCTIVE! The pump thinks that a bucket full of RODI is an empty bucket. So we attached this very safe looking copper wire to trick the sensor. No clue if this is a long term solution. Saltwater inhabitants probably won't like additional copper in the water. On the plus side: the wee little pump has enough lift to get water from ground level to the top of a 4'3" tall tank with ease. Kind of a surprising amount of power there. Really wish they made mention of the low water safety sensor or that it might not be compatible with RODI in the listing though. EDIT: So I had to take one star way. After a week of fighting with this pump, trying all manner of fixes, it is simply too unreliable. I would not trust this model to function without constant finagling for any length of time. Absolutely not worth it. The float switch array *seems* to function just fine, however. The pump can be replaced by any 12v dc pump, like those in our pet fountain. So we might swap that out to check the reliability of the rest of the system. But yeah. This pump is trash. IDK if other sellers are using a more reliable model, but this ain't it. EDIT 2: seller supplied a replacement pump: The seller contacted me about supplying a replacement pump or refunding the cost of the pump we purchased from another seller to replace the one that came with the set. (That pump is still performing reliably btw. I have yet to take it out of service.) So I now have 2 pumps from this seller and only one will switch on in RODI. Go peep at the back of the pump. The model with TWO (2) low water sensors will work in RODI! I added some pics including some teardown footage btw the models for comparison. Haven't put the new pump in service yet so I can't speak to it's overall reliability, but at least it turns on! Might update on that front sometime in the future. Good customer service. ... show more

Awesome and great value
Awesome auto top off and great price. I bought the hygger digital sensor and had so many problems and couldn’t get it to work. I went with this one and had it setup in 10 mins. The tube was long and I had plenty to work with. I hooked my rodi system to it and it is not completely automated. Would like to see a switch on it so I don’t have to unplug when I want to adjust things but for the price you can’t beat it. ... show more

Durability is a zero😔
Let me say for the price it’s not a bad item to top off a fish tank but I got this to fill a reservoir and I think the usage was too much for the little pump and it burnt up straight away. It worked at first so I can’t say it was defective but I can say it did not last a week in my application. So 1 star was all I could muster. If your getting this for your fish tank I think it will be a excellent buy ... show more

3 years in use for reef tank
As you can tell by the coralline, ive had this for 3 years now and never once has it flooded and belive me my snails will try. The pictures attached is after i get home and once again a snail decided to clean the lower float. The top safety float has stopped it from flooding COUNTLESS times. My only complaint is that it doesn't fit a normal tank rim and i broke it, glued it and just made it work. One more half complaint is i wish the shut off was closer, For me thats 5gallon difference which thows the salinity off, but to their defense id rather have 5 gallows dump in and it not overflow from a snail possibly being able to sit on both floats simultaneously ... show more

Works great, very small
This is a great, small piece of equipment. As you can see on my photo, it’s so small, the cord for my power head partially obscured the device so I had to circle it to make it noticeable. I’ve had it running for a month in my 36 gallon bow front and have no complaints. The salinity in my tank has been a steady 1.026 for every measurement. I was hesitant to spend money on something that can be done with a daily dump of fresh RODI by hand, but I was prone to forget to do that some days and I like that my pets can now rely on consistent salinity for their home. ... show more

Failed impeller
I have purchased this pump twice for RODI auto top off for my saltwater aquarium. Both times it has stopped working within about a year and upon inspection I found the impeller has disintegrated (magnet not on shaft or impeller broken from shaft) is there a more durable product that can be recommended or is there a replacement part that can be installed to salvage the pump housing? Otherwise pump does what it’s supposed to and keeps tank at correct level. Thank you. ... show more
