Product Questions

Can you guys help me please? I'm looking into automating my 75gl reef aquarium. I like the Apex for its wireless/cloud features. Looking to monitor Temp, PH, Alkalinity, and eventually Calcium and Salinity. With all the various modules it can be confusing. Could you all tell me what equipment is needed for the most bank for my buck. Thinking all I need is the Apex Jr. for power supply and can always add on if needed.
Question by: Vincent Maggiore on Jun 26, 2016 4:28:00 PM
Great question! Honestly, the most bang-for-your-buck, as far as future upgrades would be the newest Neptune Apex. It offers pH, Temp, Salinity, and ORP monitoring out of the box! :-)

Packing up my apex for a move. How should these probes be stored for long term (about 6 months)?
Question by: David Mastracchio on Mar 20, 2016 2:04:00 PM
Great question!
The probes will last around 1.5-2 year maximum and may need to be replaced by the time the tank is being set up, however they can be stored in probe bottles listed below with solution. Feel free to let us know if you have any further questions!

New to the controllers. Wondering if the probe needs to be taken out and cleaned or you just calibrate and put it in your tank and leave it? If it has to be cleaned how often? Thanks
Question by: Corey on Jan 19, 2016 4:04:00 PM
Great question.
It is best to clean and re-calibrate the probes. When cleaning the probes should be unplugged and removed and rinsed with water to take any build up off. This can occur once every few months. probes do need to be replaced to accuracy once every 1-2 years. Feel free to let us know if you have any further questions!

Do I need to buy the salinity module in addition to the APEX controller that is $549 in addition to this probe to make all things work best together?
Question by: Alex Chandler on Mar 10, 2016 2:29:00 PM
Great question!
You will need the PM2 module in addition to the apex and salinity probe. Feel free to let us know if you have any further questions!

How long is the cord on these? If it's not long enough to reach where I want to put my Apex is there any way to extend the cable?
Question by: Brian on Mar 12, 2016 9:18:00 PM
Great question!
These will have a 10.5 foot cable attached. You would need to look into a BNC adapter cable to increase the length. Feel free to let us know if you have any further questions!

  • Works well By Button32 on 3/6/2016

    I just like a lot of people had a hard time cal. But did get it done. I think I had a hard time because the solution was cold. After cal. It works great. I used the pinpoint solution after I used the apex solution and it work fine. I have only been using it for a month,but have not had anything to complain about.
  • Solid By Steve on 1/27/2016

    Had to standardize it a couple of times in the cal solution. Then had to tweak my tempt sensor a touch when I moved it over from the base module for temp compensation. Not really a big deal. Readings have been solid and dead on since initial setup. No complaints here.
  • Great By Fishfreak on 2/24/2015

    This is a great add-on for anyone using an apex. I did find out that in order to keep my readings stable is was very necessary to add an addition temp probe to the PM2. At first I was getting crazy numbers and once I added the temp probe it has been spot on ever since.
  • Work great By Chavinpat on 2/13/2015

    Read the instruction and warning carefully. Avoid bubble, avoid others electrical equipment, and more importantly do not knock the probe on any hard surface. It is not hard to calibrate, but be sure to use calibration solution from Apex. I tried other brands, and the reading were off.
  • Fairly stable, but subject to bubble and particle interference By Joe on 1/5/2015

    I've been running the probe for a little more than a month now, and overall it works as you expect. If you place it in an area of the sump or tank that does not have any bubbles, it is fairly stable and accurate. It does bounce around 0.1 ppt, so if the true salinity is 35, you will get values between 35.1 and 34.9, but this is within the spec of the probe.

    I give it only 4 stars because the probe design makes it very susceptible to bubbles or detritus. I use a lot of different conductivity probes for work (i.e. YSI, hydrolab, seabird, etc), but none have this kind of problem. It is a poor design and I don't know why Neptune Systems uses it. You cannot place this probe in an area with bubbles unless you add some kind of protection against them.
  • disapointed By joe on 12/29/2014

    I wish I would have known I needed to purchase the Neptune Systems Conductivity Calibration Solution. For as expensive probe, you would think the solution would be included. Neptune should have its dealers note solution is needed. I was disappointed after waiting for delivery to find out I needed to make a second order so I contacted BRS and the rep seemed to care less, I asked for his managers name but he has not provided it. Wait its not over, I ordered the wrong calibration fluid I think? I received the 475 and i need the 53000??? so here i set waiting on my third order to ship??
  • Kinda Finicky. By Franklyn on 12/17/2014

    The probe is kinda finicky to calibrate. Took multiple times of calibrating to getting working right. After working great for a few months it began to drift. Again was a pain to recalibrate. One calibrated its pretty accurate. I compared it with my refractor and there's a very minimal difference..
  • Works great By Cesar on 12/13/2014

    It was a bit challenging to set up and calibrate but once I did it has performed great. Very precise and a great layer of redundancy to alert me if something has gone wrong with my ATO or automatic water changes.

    Get it.
  • Neptune Systems Conductivity Calibration Solution is required in separate purchase By Brian on 12/9/2014

    I wish I would have known I needed to purchase the Neptune Systems Conductivity Calibration Solution. For as expensive probe, you would think the solution would be included. Neptune should have its dealers note solution is needed. I little unhappy to have to place a second order for the solution. Contacting Neptune.

  • Please add the solution or atleast reccoment to buy it By steve on 4/19/2014

    Please notify it doesnt came with the solution, now i have to order the solution before instal this, i was thinking it came with the solution like the ph one, for the cost of this im preatty sure u can send the solution like the ph. Regards
  • Awesome product By RedReefer on 1/31/2014

    Once dialed in, this probe is rock-steady! With my Apex I can do automatic water changes and I can set my auto top off to pull RO/DI water OR new saltwater to fine-tune the salinity to 35 PPT, automatically corrected for temperature. I do this from my iPhone! :) however, the calibration procedure is tricky at first. You need to be patient with it and let the numbers "settle" for a good 10 minutes or so and keep the solution the same temperature as the tank-water. (Many people seem to have trouble initially calibrating, myself included.) Once calibrated, it will probably drift down slightly due to micro-bubbles. This is easily fixed (if placed in a sump) by placing the probe at a 45 degree angle away from bubble sources and placing a foam "barrier" a few inches a way from it. I just use a cut-to-fit filter pad.
  • Spot on! By Christopher on 11/11/2013

    This is a great conductivity probe. Some have reported problems and I to had problems initially. I found for me the key was to be patient when the probe is in the settling process during calibration. It takes some time for the probe to settle out. Another issue was placement. I have this probe in the return section of my sump where circulation is great and micro bubbles are at a minimum. One last thing is the temp probe, you must use a temp probe to gain accurate and STABLE readings. If not your salinity reading will change with temperature. Great product by neptune and great service and prices from BRS!!!!
