    So I've been looking into dosers for a friend, and I'm seeing a surprising amount of mixed reviews.

    - I see tons of threads praising the eKoral, then met someone who had theirs dump the other day.

    - Kamoer are lab/medical grade, but their stuff for aquariums has been less than stellar.

    - Kore 5th is okay, but I see lots of people complain about dumping and failure.

    - Neptune DOS is a timebomb, it WILL dump for sure on you. I don't trust neptune with that stuff.

    - New Bubble Magus dosers have their timers die in about a year (check reviews everywhere, seems 1/3 reviews are about the doser turning into a paperweight).

    So whats the deal here? What would you guys suggest? None of them seem to stand out in a very positive manner.

    I’m about to list a Bubble Magus T01 for sale shortly for $125. Been working flawlessly for a little over a year. See if he’s interested!

    Really? Maybe I'm lucky, or the newer models aren't as good, but mine has been going 10 years strong.

    If you already have an Apex get some BRS 1.1ml dosers. Been using mine for about 4-5 years with 0 issues. Still on the same dosing tubes also.

    I used BRS dosers for some time. They are good actually. Only problem is if the tubing start wearing out and you do not change it, it will not dose 1.1ml a min. So you need to keep an eye in the tubes.

    I use BM without issues, but not sure you can beat a used masterflex with dual heads on a timer. Been using a couple for dang near a decade on FW tanks changing 30g a day.

    GHL all the way. And you have different types, so it not one doser type fits all needs.

    You have the Maxi which is like the Apex DOS.

    Then you have the standard GHL 2.1 dosers.

    I am using both in multiple types of setup, stand-alone and connected to P4 controllers. Very happy with them.

    Think it’s all hit or miss on the dos scene.

    Between use, chemicals, calibration, location of pumps and containers, tubing used, tubing location and programming.

    Everyone has a different setup and opinion.

    I am currently using DOS without any complaint. Why would it dump high amount if only dose small amt each time?

    I had the control board on one of my dos’s get corroded due to humidity and it dumped my whole container of Kh2Po4. Luckily it just spiked phosphates and I was able to crank the fuge for a day and bring them back down. I now know to not keep the dos anywhere where there is moisture in the air

    I’ve had a GHL doser 2.0 in my cabinet for 3 years without cleaning and it’s never skipped a beat so I’d say that gets my vote. Humidity and some small splashing on it hasn’t phased it yet.

    If you get a revision 2 or recent production Kore doser, it's not horrible BUT make sure to use the Windows software for it, not the Mac. Also, it's incredibly buggy and you have to learn all the quirks of the software. It does have an incredible range of features such as temperature alarm and optical ATO etc. It also has higher quality and relatively quieter Japanese dosing motors. The hardware is a power coated steel that is pretty and nicely made. There's also a definite unresolved bug where if you attempt to use the manual dose method it will dose your tank infinite amount of times because it seems to go into an infinite loop. So try to be there and monitor if you're using manual dose.

    If I were to do it again, I would get a GHL 2.1 SA.

    I believe only GHL, DOS, and the Pacific Sun Kore doser are using German made or Japanese made motors. Everyone else is using cheap Chinese motors that will probably die or constantly swing wildly out of calibration over time.

    I have a DOS coming in today for AWC purposes. I also have familiarized myself with the necessary programming to setup and fail-safe it. Question that I have it how much of the issue are "user" errors and how many are product failures?

    I know that I am using numerous optical sensors and"WHEN" statements and anything else that I can put in as a fail-safe to prevent the DOS from draining my tank or dumping in too much fresh salt mix.

    I've used bubble magus dosers for years in all my systems with no issues. I've been debating about replacing with the Neptune DOS since the Trident was released.

    For a doser, I have had a Vertex Libra doser over 5 years and haven't had to change the heads or tubing. Finally going to retire it more than likely. FYI, I also bought it used as well. So that pump has been super reliable.
