Help for Greg on loud buzzing By Aquahub.com on 10/27/2014
Aquahub.com would recommend this product to a friend
The buzzing is probably caused by having a pump or other source of magnetic interference too close to the float switch. As the pump rotates, the magnet inside creates rapid waves of magnetic force which cause the reed switch to flutter and the relay to go on and off very rapidly which creates the annoying buzzing sound. Move the pump as far away from the float switch as possible, this should solve the problem. If the buzzing has already caused the relay to fail, write us at Aquahub and we will send you a new relay. Thanks
Overall good auto top off, but very loud and annoying! By Greg on 10/5/2014
Greg wouldn't recommend this product to a friend
For the money the auto top off has worked good. but the unit is pretty loud as it turns on and off repeatedly.
My tank is in our living room and its REALLY hard to ignore the continuous buzzing sound it makes every time the float switch makes the unit kick on. I wish there was a fix because at times it can be kicking on every few seconds
Great little kit By JR on 8/20/2014

I put this kit together just a few days shy of going on vacation (yes, the ultimate test) and paired it up with a two gallon bucket of RODI and a tiny fountain pump. I am super happy at the results. My sump has yet to sway from the top off point and just like putting a model car together it was fun and gave you the options to really build your own design. Great and affordable kit.
Works Great and Cost Effective! By Shaun on 7/9/2014

When I decided to finally add ATO to my sump (which I should have done a while ago looking back), I was looking for a simple and cost effective solution as I needed to keep to my budget for this upgrade. After considering all the options, and the price tags, this was the clear winner! Paired with a TOM Aqua Lifter pump, this has been a flawless solution. Easy to build using the provided instructions, I had it built and in operation within an hour. Molding the float mount took the longest but was simple though tedious. The components provided in the box seem of quality, but will be easily and economically replaceable if they become defective. This would not be possible with more commercial ATOs in most cases and I prefer self repair. Would definitely buy again if I had a need for a second one.
good system if it's done right. By The guy from Langley British Columbia. on 2/23/2014

If you are electrically inclined there good and work well, The 12 volt part has to be carefully connected and crimped with a proper crimper for sound operation and connection to the relay. Other reviews I've read said they quit working and I think they have not made sound connections which on low voltage is very important, my background is in HVAC and controls so I know this is a very important point to make.

I thought I would try this DIY auto top off kit. I have had other name brand ato's and not been very happy with them. So if your electrically inclined it's a snap to make up. I like the 2 float system for extra shut down safety redundancy. It works great so I'll get another for my frag system. All the parts are good quality as well.
Best value for the money By paul on 11/5/2013

The kit took a little less than an hour to assemble. (The biggest tasts were drilling holes into the little bottle to keep the float switch free of snails/junk.
The electronics were easy to screw and snap together. The relay also has a little diode (to tell you it's on, in case you don't hear the loud click) -- and I drilled another hole into the black hobby box and put clear silacone over it to make a window.
But for $40 bucks, I've now bought 4 of these for my tanks. The float switch works fairly precisely. I rigged it to a cord with multiple outlets, so the top off tank gets a quick dose of calk from a sealed bottle when it turns on the top off pump. brilliant
Great product! By Mike on 8/5/2013

For the price of this product you cannot beat it. the instructions were very helpful and everything went together with ease. You do have to buy an extension cord for the kit. But for the price of the kit you can't complain. some of the reviews complain about a clicking noise from the relay, if you have it mounted in the box you can barely hear it. I have my unit mounted on the outside of my stand and asked my wife if she could hear it and it was a No.
great product will buy more for my other aquariums.

I set this up to keep my nano tank water level filled. With the nano tank the evaporation can cause havoc. Having this system set up keep me form worrying about that while I'm away or when I go on vacation. The system was easy to set up for a DIY project.
Super Easy to Install... By Larry H on 3/28/2013
Larry H would recommend this product to a friend
I bought two of these units last week. They have been working flawlessly. Sorry I didn't put them on sooner!
I'd say there was only one thing that wasn't much fun. That was the cutting and bending of the plastic bracket that holds the floats. I wished they would redesign it with some sort of universal sliding bracket for the floats to mount to. I'm closely monitoring my water levels in my refugiums and making sure these ATO's are working correctly. If I find a glitch or a hiccup, I'll be reposting what happened. So far, so good though!

I used this for a while with an aqualifter pump. It is a good entry value for ATO but mine would not kick on anymore after 8 months of use. I changed the relay, but that did not solve the issue. It must lay somewhere in the float switches.
Reliable By Matt on 1/17/2013

I ran one of these kits on my 29 gallon for just over a year with no issues. I just installed one on my 120 gallon this last week. Super easy build and install. All you need is a cheap extension cord to wire into the relay so your pump can turn on and off. The float switches have been reliable and there is an emergency switch in place in case one does fail. While the moldable float switch holder does work for most people (I used in on my 29 gallon setup), I opted to build my own holder out of acrylic for the new build. Overall I would recommend this as a good affordable ATO solution.

The kit requires an extension cord. Otherwise would be 5 stars. Easy directions. Hanging bracket is easy to mold, it turns clear while flexible.

If your budget is low, this is a good kit to have. The valves holder is flimsy but it works. The 12v power supply and relay can be replaced easily and available on their website, keep a spare one. I have one system for water top off and another system for kalkwasser in the same sump for a few years, replaced a relay once.

Michelle wouldn't recommend this product to a friend
after putting this thing together it worked pretty good for a week or 2. then it kept over filling, the bottom float was bad. company sent me out 2 new floats. had it for a little over 2 months now and today i noticed its not kicking on anymore regardless of what the floats are doing. wired on new floats and still not kicking on which means now the danged relay is busted. its been enough of a headache that i really wish i had just spent an extra 20 bucks. it is an eyesore for sure with wires going all over the friggin place. some seem to work great per reviews, and others seem to be crap. i have contacted customer service again but may end up at radio shack for a new relay.

This is a somewhat interesting project but the importance of ATO performance and the fact that well engineered and manufactured products can be had for only a few dollars more mean I will look elsewhere for my next ATO.
Your crazy to not have ATO automated By pdog22 on 4/9/2012

This is probably the best value you will find for what it does. The ATO has worked perfect, and you can trust it with the dual water level checks. If you have any skills you will be able to put this together, no problem.

Do yourself a huge favor an don't waste your money on this,pay the extra money an get a built one. Bracket is cheap that you have to mold yourself. An when it is all said an done you don't have near enough wire to run it. If you don't mind a bulky eyesore this is the one for you.
Over all good product I recommend it for any tank By Sean on 2/23/2012
Sean would recommend this product to a friend
My only complaint is the relay I put the system together like the instructions said, and the next day herd the relay buzz for a few seconds off and on for 5 minutes every now and then. So I ended up removing the relay and replacing it with a fuze holder and fuze (5-8 amp just to save the switches). Now the switches flip and the pump kicks on with no noise just smooth operation. I use the Aqua Lifter Vacuum Pump it is very quite i would recommend this pump for the system...

this product was real easy to install and assemble. float switches work like a charm. if there was a con to the product at all it would be that the relay switch makes a clicking sound every time the float switch activates it. this is not really noticeable if placed under the tank near the sump or behind cabinets. over all i am happy with the price and ease of this product

Just set this up and it's been running about a week. This is a great little ATO for the price. It was very easy to follow the included instructions (lots of photos). The relay is pretty loud and the sensor is pretty sensitive. My pump normally kicks on and off repeatedly for about 2 minutes and then I don't hear it again for a couple of hours. My only concern with it is that it does take up two plugs instead of just one. But for the extra $60 I saved I can live with it.

Great product, but had a small problem about a week after it was installed. The relay "broke" for apparently no reason. I email the manufacturer and they sent a new relay right away. I couldn't wait so I took it to Radio Shack, they had the part for $7. Now, I have a back up just in case.

Anything to make it simplier! By Phil on 5/4/2011
Phil would recommend this product to a friend
This is a great little DIY kit. Got it all set up with no problems. Instructions were easy to follow, the only problem I see is that even with a 'slosh/snail guard' it still needs to be paid attention to. Only of my floats, in a guard is not traveling correctly and making the on/off as smoothly as it should. Gets partially there and the relay will buzz for a second or two before kicking on or off. This is just maintenance and probably just needs cleaning, I'm guilty of ignoring it. Besides that, works great... been set up and using for 3 months with no issues. Just make sure cleaning the switches is added to your maintenance schedule.

I'll echo what the others have said. It's a kit that works, for cheap. I'm going to go ahead and say the kit is flawless...with the following exceptions. Biggest thing that bugs me is that the relay is really loud. Each time it kicks on/off, I can hear it throughout the room. Add that to the fact the float switch is pretty sensitive, it's clacking every 2 minutes. Second thing that keeps it from being completely perfect is not the kit's fault. It's the float switches. I've already had one get stuck in the up position. (No water pumping in, sump ran very low) I just beat on it a little bit to bang the reeds inside around. Been working fine for months now.
Awesome top off By Todd on 3/12/2010

This will do anything the name brands will do at a huge savings . It requires that you put it together but as long as you can read and follow the directions to a tee it is simple. You can have an Auto top-off . A small tip instead of cutting into the wire of a aqualifter or other pump just use a cheapy lamp type extension cord and you can hook up as many things as you have outlets for.I dose Kalk and top-off with RO at the same time it runs about 3 times an hour. But you cant even hear the aqualifters run just a slight trickle of water WARNING:To avoid siphoning back out of your tank dont submerge the line in your sump.
Works Great! Very Happy. By IbnOzn on 12/14/2009

I bought one of these about 6 months ago. It was pretty simple to put together, the directions were easy to follow and it works very well. I have an Aqualifter on it for the topoff and also a Maxijet to circulate the water in my reservoir. The only issue might be that the magnetic float switch can be sensitive and will tend to buzz if situated right next to another magnet such as a large pump— but literally we're talking right next to. Mine sits about 4" from my return pump in the same sump compartment though and works just fine. I'd definitely buy another one of these and would recommend it to other people.
