Hello! I have a gently used Neptune DoS that I am selling now that I have swapped it for Versa pumps. The Dos has a manufactured date of "Nov 21" and was purchased on Jan 31st, 2022 from BRS. The DoS was in use for 4 months and ran only at its slowest setting to reduce noise level and extend...

I have 2 Neptune DOS pumps brand new in box selling for $250 each and I also have 2 brand new SKY LEDs asking for $800 each. I will post pictures once I get off of work. I will pay shipping anywhere in the Continental US.

Am I correct in thinking that setting a Neptune DOS profile through advanced settings on the DOS means the set schedule will not run? I can't see any other way to remove the interval. Screenshots attached.

Posting it for another reefer. Want to sell it as a pair. Practically brand new used under a year. $375 for each combo. Shipping available at buyers cost. Text (805) 701-1682. Two pairs available

If anyone has a DOS or Kalk stirrer they are willing to sell I’m looking to buy. I’m in north Texas, can meet locally if not local must be willing to ship.

Im about ready to start dosing saturated kalk to my 65 gallon reef. Really only need a single head, trying to decide between these 2 dosing pumps. My plan is continuous dosing at a very slow rate throughout the day. May try only at night. We will see. But which would you pick and why?

Ok this is probably really simple for some, but I have my DOS 6_1 and 6_2 completing daily 1 gallon water changes from 07:30 to 09:30. I want to turn my Apex ATO system off during this time. I opened the config in both the 6_1 and 6_2 and clicked on the advanced tab, but there was nothing even...

Willing to trade my Neptune DOS for a GHL maxi doser or possibly a GHL doser 2.1 , the DOS is less than 2 months old and barely used

Hello everyone! So my story begins with the first DOS & DDR Dosing System Package that I purchased around 6 years ago. And then I couldn't do anything; my unit was always with bubbles in the airline and draining back into the container. I have the Check Valves installed at the end of each...

Howdy! Hopefully an appropriate place to post. I've noticed over the last week or so my Alk has started to swing a fair bit from low of 8.46 to high of 9.05 with my set point 8.6 I've adjusted the dosing baseline to the average over the last month and just today increased my testing from 4/2...

Anyone have a used Neptune dos before I buy a new one?

I have been inspired by BRS’s recent video on Kalkwasser mistakes and they mentioned that a dosing method for adding Kalkwasser is a good way to go vs ATO. My question is two part. Based on my limited experience with Apex Dos and Trident 1. Can I fully automate my Kalk dosing. Program it to...

Hey everyone, I just recently got an apex and am looking to set up some auto water changes with the dos system and have a couple questions: -If I have a 20g tank, is it hurtful to do a 1 gallon a day water change? I currently do a manual water change about once a week with 4 gallons or so...
