dos

Neptune Apex DOS, used very little, 220 shipped. Ecotech MP40WQD, August 2019 but no sticker, 280 shipped. Hanna low range phosphate checker with reagents, only used 4 months, 35 shipped

Has anyone used 1 DOS to do auto water change on 2 different tanks? My thought is to use solenoid valves to control the water flow. Or to run parallel water Lines to each tank off the main lines from the DOS. If you have done this please let me know how you done it. Any thoughts?

I have found that i prefer to test my water the old fashioned way. So, I have decided to sell my Neptune Trident with 6 months of reagent. Now in my experience anyone whos has baught a trident, soon wants the DOS as well. For this reason I have decided to include the DOS and DDR. For...

Did I miss something in the past few month!? (Other than covid 19) I can’t find a neptunes dos anywhere! All the usual websites are sold out or outta stock and amazon has one for $469.00 Is neptunes making a new version I should wait for or is corona virus impacting manufacturing since...

Hey everyone I originally posted this in another thread but decided to expand on it a little and put it here… I have been watching reefing videos on YouTube for around 10 years and have always wanted to get into the hobby. Around 4 years ago I purchased a used 270 Lt CADE HL800 tank (800w x...

Looking for a DDR, let me know if you have one for sale! thanks!

Anyone want to offer thoughts on my use of silicone airline tubing for my dosing lines? I've had this setup for almost a year and set a reminder to check how they're holding up - all seem fine. I'm pushing Alk, Ca, Mg and NoPoX through them. Just come to calibrate my Apex Dos which I use for...

Looking for a replacement DOS since mine went out. Let me know what you have.

Never used Trident from saltwater aquarium (so it has the fancy drawing) and a DOS that’s BNIB. I don’t have time to try and set up and after 4 years still have a fowlr... So after some though and sitting on this combo for 6 months I think I’m just willing to part with it as a combo. Looking for...

Anyone have a neptune dose for auto water change and when you watch the return line you don't see water going back into the tank ? I am watching water leave the tank but not enter. When I look at the neptune dose log it shows even return for taken out.

Hello all, First off, I am sorry if this is the wrong area, it seemed right. So, I have the Neptune Trident and recently acquired the Neptune DOS. I used to have a different dosing pump, it was dosing ESV B-Ionic 2-part in the morning. Now with Trident+DOS I see that I could use the automatic...

Hello, I am looking for the complete apex system with trident and dos. I am trying to see if this is possible and how much people are wanting for this package. I was thinking 1200-1300 is the prize range I am looking to spend. Is anyone interested in selling for this price?

I'm selling a new unopened Neptune Apex DDR. Price is $160 shipped to the 48.

Having just acquired a Neptune DOS, I have to find the two-part solutions to use in it. In the USA this looks easy, from BRS. But here in the UK finding a decent supply of calcium chloride and sodium carbonate through an aquarium shop is proving difficult (at least, I'm failing to find one)...

I really want to do away with my Apex and move over to Profilux. One of things holding me off (other than time and money lol) is that you can only program 8 times to dose throughout the day. One of the few (but major) benefits that DOS has over Doser 2.1, is that you can set time-frames for...

So I am about to instal my dos and my return chamber is lagging of space. So do I have to dos where my return pump is ore can I do’s where my skimmer is with out any problems? I have the Red Sea 170
