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.

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...
