I have about 6 of these on aquariums I maintain and once there up all is good. The other thing is your not making pharmaceuticals your using hobby test kits and if your making your own additives there is a little error involved. From reading these reviews, enless they have changed the calibration process it sounds like your not doing it right. I have not had any problems. .!

I have purchased four Jebao DP-4 units. In all four units the packaging was intact and there was no indication that the units were second-hand or re-sold. All the units had the pump unit, a power supply and an extra pump head. The unit cases were all apparently solid and cleanly put together. The menu interface allows for setting date/time, pump dosing schedule programming, pump volume calibration and manual pumping, and all the functions were reasonably easy to access. As other reviewers have noted the clocks can drift noticeably but no worse than your run-of-the-mill bedside clock radio might, at least as far as I can tell. The most important part of these pumps, however, also seems to be the weakest point. Among the four units (four DP-4 units total 16 pump heads) I've purchased three pump heads have proven unreliable to the point where I don't use them, even after switching out several pump heads (I now understand why the put an extra one in each box). The peristaltic pump head unit is a plastic assembly with three plastic rollers pressing a latex tube against the outer shell of the assembly, and the whole assembly is basically press-fitted onto a bare metal shaft. This arrangement is clearly economical (seeing as how many competitors are three times the cost of these pumps) and when it works, it works--usually. Unfortunately in some cases the shaft is prone to slipping or sticking for whatever reason, and sometimes changing a pump head improves the situation. Sometimes the pump heads work consistently for weeks or months but sometimes they'll work for a few days and start slipping or sticking. It seems certain motor shafts are just problematic for whatever reason. The calibration method involves priming each pump and filling a 100ml container while a counter counts up from 1 to 250. Of the four units I purchased when calibrated before being placed into service three of them proved generally consistent with the factory calibration, but in the case of one unit none of the pumps could reach 100ml even at the maximum calibration setting of 250. I'm not sure whether this behavior is attributable to the electronics or the pump head. For my needs the actual volumes hit (>90ml) were adequate for my needs, but aquarists with precise dosing requirements might regard this as a caveat. So if one is looking a dosing pump and working on a budget, this is a workable option if one accepts the limitations and a certain level of unreliability.

Construction: The buttons, LCD, and pump heads seem to be of pretty high quality, though the case feels cheaply made. The power jack on the unit I received has a poor connection and the unit will lose power if the cord is angled incorrectly. This is mostly just an annoyance since the unit is secured inside the tank stand. The cord that comes with the unit also sticks straight out of the back, so although the unit itself is only roughly 6 inches deep, you need to provide an extra inch or so of clearance for the plug. Space in my stand is at a serious premium, so this wasn't an option for me. I had to buy a new AC power adapter with a 90 degree barrel plug in order to reduce the clearance in the back. Although the instructions state that the unit isn't waterproof, mine survived, so far without issue, after being sprayed with several gallons of saltwater due to a burst pipe fitting on the tank return. While I wouldn't recommend replicating my unintentional experiment, it does seem to prove that the unit is fairly durable. Use: The unit doesn't come with tubing, so you will need to pick up some airline tubing before you can get started. The instructions are poorly written in broken English and are missing words or pictures in key steps- don't bother trying to use them. Champion Lighting has a much more clear and complete version here: http://www.championlighting.com/pics/doserpics/Jebao-DP-4-Instructions.pdf Programming isn't completely intuitive, but is fairly straightforward and isn't nearly as difficult or time consuming as some reviewers make it sound. You will need to set the time and the volume of each separate dosing event on each pump, so this could get tedious if you're dosing more than a few times a day, but if you're only dosing 3-4 times a day you can easily reprogram each pump in about a minute. Once calibrated and programmed the dosage is very precise and consistent. It will retain the settings even if power is lost. When running, the pumps are pretty noisy- probably loud enough to hear over a TV at normal volume. In most applications they wouldn't be set to run for more than a few seconds so that's not likely to be a problem in most cases. However, if the tank is in a bedroom and you're a light sleeper you may want to set the unit to only dose during times when you won't be sleeping.

This pump is not bad for the price. For those of you who are having problems with the heads not pumping fluid there is a video on youtube how to fix it. If its not keeping your settings after a power outage replace the little battery inside. The measurement accuracy is off a little when a need a 3ml dose i have to set mine at 2ml. Overall not to bad of a pump. Also get check valves to keep the lines primed.

If you care about accuracy in dosing this is not the product for you. You can only program the dosages by 1ml at a time, meaning you can not program 1.5ml for example. I've tried tuning this pump & sadly the numbers don't match. Just save up money for a more expensive dosing pump or get the single Bulk Reef Supply dosing pumps, which are around 70 bucks each.... After a month of use, I noticed that the chemical in my dosing reservoir was not getting any lower & the pump was completing failing to add anything to the tank. You need to check on it periodically to make sure the pump is doing its job.
