Great product! By William on 7/26/2014William would recommend this product to a friendI am using 2 of these at the moment. One on my 240 Reef and one on my 75 gallon reef. Both as ATO's. I use a small pump (250gph) to deliver the water. I have been running one of these for over a year with no issues. Save your money and go this route you will not be sorry. People complain about float switches, just check on your system and do your regular maintenance.
Great for the price By MICHAEL on 6/23/2014MICHAEL would recommend this product to a friendDoes what it is supposed to do. Keeps the water level right. Do be aware that you may need to adjust the internal run time if your pump can not keep up with the rate of evaporation. However that is a very simple adjustment
Disappointed By zedagyrl on 6/5/2014zedagyrl wouldn't recommend this product to a friendI have to be able to get this to work properly. I used a aqualifter for my pump and it could not pump enough water into my sump before it "time out". I adjusted the internal timer to run as long as possible and it will work for a few days and keep my water topped off then for no reason it times itself out and never resets to run again.
Potential disaster By Daktari on 5/9/2014Daktari wouldn't recommend this product to a friendIf you are going to use this I advise that you run the inflow through a float valve. If the solenoid malfunctions in the on position you may have a flood or drastically reduce salinity depending on your set up. My LFS stopped selling this unit after several unhappy customers tried to return them. At least the float valve will stop the water.
Another problem I have experienced 3 times in the first month is that the unit will shut off and not come back on. I reset the internal timer to allow maximum run time and will see if this fixes the problem. I attribute this to the slower fill rate due to the float valve. We shall see if the problem is fixed.
Also if your pump is at a higher level than the end of your input hose regardless if it is in the sump water or not it will create a siphon and the water will continue to flow after the pump shuts off. You will need to install a siphon break.
The power chord and the leads for the float sensors were way too short for my application.
I may go back to a gravity fed set up with a 12 dollar float valve.
Good System, but tricky! By Rod on 4/9/2014Rod would recommend this product to a friendLove this reliable system, but had problems for months trying to get it to work right. Finally realized that sump water was back siphoning back to the fresh water container ( 5 gal bucket) after the pump shut off. Had many friends look at the system trying to figure it out, but nobody detected the reverse siphon. After raising the tubing out of the water in sump, it has worked great.
EXCELLENT!! By Lawrence on 4/7/2014Lawrence would recommend this product to a friendI've had mine for just over a year. Helps keep my Sump water level in check... works perfect right out of the box. No problems at all.
automate for best results By Michael on 3/18/2014Michael would recommend this product to a friendAfter automating my top off, my tank has been much more stable and growth rates have increased. I recommend cleaning the sensors every couple of months to avoid salt build up that can cause a failure.
Disappointing By TankLady on 2/13/2014TankLady wouldn't recommend this product to a friendI used one float switch at a time, each failed after a couple of months. Additionally the unit itself freezes occasionally. Needing to be unplugged and plugged back in to make it work.
Not worth the money By jerry on 2/9/2014jerry wouldn't recommend this product to a friendhave to keep resetting can never keep proper water level in my sump
Excellent!! By Dr. Chad on 2/7/2014Dr. Chad would recommend this product to a friendI've had mine for just over a year. Helps keep my Sump water level in check... works perfect right out of the box. No problems at all.
Works good for Cheap ATO By Redfish on 2/5/2014Redfish would recommend this product to a friendI have two of these units one on a 275 gallon tank and another on a 120 gallon tank. They are cheap and work well. I am using lime water with these and have had no problems to date.
works as advertised By Michael on 2/1/2014Michael would recommend this product to a friendRecieved prouduct for christmas. I paired it with a aqualifter pump. The setup was easy and the instructions were to the point and easy to understand. All in all good product for the $$

what's the recommended pump for the ATO JBJ? thanks!
Bulk Reef Supply Hey Werner,
Really just about anything will work in terms of the ATO itself, its more about how far and fast you need to pump water. The most common pump is the aqualifter pump which pumps slowly and only goes a couple of feet. Otherwise if you need to pump larger distances you could use something like the 50ml top off doser.

Why do i still get drips of water out of my discharge hose non stop even after the vaccum pump has shut off the.
The vacuum pump is on the bracket at the top of the tank at lease 3 ft. higher then my R/O holding tank(no pump in here for the A.T.O.
Bulk Reef Supply Hi Jerry,
Is the water in your storage container higher off the floor then the water in your sump? If so that would create a siphon when the pump turns on and water would continue to pass to the tank after it turns off (regardless of where pump itself is located).

What kind of pump is recommended for this system thanks
Bulk Reef Supply Hi Dan,
Any low flow pump will work with this ATO. I ave personally used our 50ml/min dosing pump but find that it had trouble keeping up with large systems. I moved to the Auqa Gadget HydroFill ATO Pump due to the fact that it can be run dry without any problems, its self priming and it won't back siphon.
Another great option would be a small submersible pump like the eheim 300 or sicce micra and micraplus
Keep in mind these pumps are rated for low head heights so if you are running the ATO hose from the ground to the top of your tank you will need to go a little bigger.
I hope this helps!
Have a great day :)
