dos

Sorry about silly question here: When I mix up BRS 2 part solutions, can I double the amount of product while keeping the rodi liquid amount the same? My goal is to double the potency so I can decrease by 1/2 the volume dosed per day. (Example: DOS doses 200mL calcium and 150mL buffer daily...

Never Used Apex DOS Mfg Date Feb-2018. Purchased to set up AWC but never got around to it. Item has never been mounted or wet. Comes with box and everything that was included new. $250.00 shipped to contiguous USA. Selling because I am changing the rest of my controller setup over to GHL...

Brand new, never opened Neptune Apex, newest model, NOT the EL, this is the full, complete Apex never out of the box. DOS is also never out of the box. Long story why I purchased but decided to go a different direction. Take them both for $900 shipped Continental USA. They would be $1100 if...

Do I have to use the included power adapter, or can I connect them directly to the EB832 with the 4 or 6 pin connector? Seems strange the DOS has 4pin connection (as does the EB832) but a cord isn't included. Anyway, I'm just looking to save space and free up as many outlets as I can. What...

Help....any ideas what to do? My APEX just dumped 200ml of alk into my 350 instead of 2ml. It shows 2ml as the dose but it has put 200ml into the tank when I look at the input. I just tested with Salifert and the dKh is off the scale low. How can I save my tank?

Hello all. Selling a brand new never out-of-the-box Neptune DOS. I bought two of them thinking I would use two , and only ended up using one. The box is a little beat up in one spot, but the unit is 100% new. Includes everything in originally came with, DOS, power supply, tubing, graduated...

looking for LSM, string lights, apex auto feeder and DOS

If I am going to set up my tank for ATW with the Neptune DOS do I also need to have an ATO?

Hello, reefers! Around Thanksgiving this year, I will be leaving the country for a month, and my biggest fear is imagining what my reef is going to go through. So, I look to the thousands of reefers here for advice on what I can do to prevent the most common mistakes. Since I have been...

I have been running a Neptune DOS for over a year now and decided to pick up a second DOS.. while i was at it i decided to film an unboxing/setup/calibration/review while i was at it! Let me know if you have any questions

Selling my DDR. No issues at all with it. Let me know if you have any questions. Payment preferred through the blue “buy now” feature.

So not to bring this “dead horse” up again but I’m having a hard time deciding on which way to go? I heard awesome things about GHL but Neptune DOS is screaming at me just because I’m a sucker for integration! I don’t quite have the need for a 4 head doser quite yet and the thought of automated...

I purchased the DOS last week. I installed it on my System last Sunday. I set it up so that the Alkalinity would dose 30ml from midnight to 10AM and Calcium from 11AM to 10PM. Things were working correctly. Then on Tuesday around 6PM I was sitting in a room nearby my tank and I heard the DOS...

Hello. I have 2 kessil A160WE's up for trade for a DOS system. The lights come with power supply, spectral controller and all wires associated with them. Thanks

Considering putting my DOS inside an enclosed cabinet with my EB8's and other Apex modules. Before doing this, I want to be sure that the DOS doesn't put off any heat. I don't plan on running it continuously or under any stress as it will be dosing 2-part. Thanks!

Six months old, I'm the original owner. Purchased from BRS. Haven't marked or labeled them, in new condition. Will include a 1link cable $320 shipped.

Hi folks: long story short but after Hurricane Irma I have been dosing calcium but not alkalinity. I checked my 2-part dosing with Apex immediately after the storm, and all seemed fine on the Fusion console. Unfortunately, I forgot to prime the DOS after that major loss of power, so the pump...

Hello everyone a couple days ago i bought the new 2016 apex controller, i bought the Dos and DDR, the automatic feeder and the atk, i managed to set up the atk but have been having problems with the DOS and the Feeder and i really need to fix this ASAP since im leaving to Mexico tomorrow for an...

I use one of my Neptune Dos's for automatic water changes. The salt line got totally clogged recently. Have you guys experienced this and how do you keep your lines clear? The tubing goes into my salt mixing trash can which also has a power head in there. Both the power head and the bottom of...
