    Best Deal on Apex Probes - most important?

    Hey all - Just got (what seems to be) a great deal from a local reefer. Picking up a slightly used 2016 Apex (brain + EB832) for $250. I was going to go with an ApexEL, but it’s my first Apex and it seemed like a better deal to have extra expand-ability. It does not, however, come with...

    I’m getting a little tired/frustrated with Neptune's general attitude towards their customers...

    DAY ONE I had a pH probe that wouldn't calibrate. I even tried other probes and they calibrated just fine. After a few days of getting the runaround from customer service, constantly having to repeat what I shared in the first email, they finally let me send it in. THREE WEEKS LATER I get a...

    DIY Neptune Apex Leak Detectors

    This week we are making some simple and cheap DIY leak detectors. A leak is a reefers worst nightmare! so if you have an apex why not build a super simple leak detector? Best of all if you have a breakout box it will only cost a few bucks so you can add as may sensors as you want!

    What is an acceptable margin of error for Apex brain/PM1 pH readings?

    I had a heck of a time getting my (brand new) Neptune probe calibrated. I had to send it in for "diagnostics and repair." While waiting, I purchased a Milwaukee probe and BRS probe. Once the Neptune probe was returned I tried all 3 and all 3 calibrated well. But would eventually drift...

    Will Neptune ever release a module specifically for an additional I/O port? (2nd breakout box)

    I'd like to have another BreakoutBox. But buying a second Ph module (or similar PM module) for 90$ is asking a lot. I feel there should be an option for this by now. Any chance we'll see this at some point?

    Neptune FMM: I'm using 3/4" PVC for return. Should I step down to 1/2" sensor, or up to 1"?

    3/4" is a pretty common size. It seems really strange that there is no 3/4" sensor option. Especially considering the price difference is 30$ vs 60$ !! Anyway. I assume stepping down to 1/2" would restrict flow a bit... But is it really enough to even worry about? Thoughts?

Selling to buy equipment for a smaller cube I'm putting together so a trade for an MP10 would be considered. I had the pump soaking in...
