I use a Neptune DOS only because I STILL can't get my hands on an Ecotech Versa 4 pack. I love Echotech products but they really need to get their s**t together. But if you go the Neptune DOS route, be forewarned that it is loud. Mine is in my storm room with 1 foot thick concrete walls and a thick door and I can still barely hear it. If you choose to do 3 gallons per day like I did, it will turn on frequently and if it's loud to you you will get tired of that really quick. Also, If you use the DOS for AWC the right side is suppose to spin backwards. I could not get mine to do that but there is a thread out there that has a work around. Mine works great like this.
Reef safe with caution. Lol
I would also add that this is one area that you want a quality piece of equipment augmented by a controller for redundant disaster control.
What?!! They just upgraded it and now they are phasing it out? This is disappointing and distressing. My future plans for my 2nd tank were with Echotech.
I actually think now that I took what I was told wrong and they aren't discontinuing it, but they have had some setbacks and delays in production, and that is the reason they are significantly delayed and not likely to be seen very much any time real soon. So not out all together but still expect some more delay.
Much better situation. Still disappointing but at least there is light at the end of the tunnel.
