I purchased the DOS last week. I installed it on my System last Sunday. I set it up so that the Alkalinity would dose 30ml from midnight to 10AM and Calcium from 11AM to 10PM. Things were working correctly. Then on Tuesday around 6PM I was sitting in a room nearby my tank and I heard the DOS...

Hello. I have 2 kessil A160WE's up for trade for a DOS system. The lights come with power supply, spectral controller and all wires associated with them. Thanks

Considering putting my DOS inside an enclosed cabinet with my EB8's and other Apex modules. Before doing this, I want to be sure that the DOS doesn't put off any heat. I don't plan on running it continuously or under any stress as it will be dosing 2-part. Thanks!

Six months old, I'm the original owner. Purchased from BRS. Haven't marked or labeled them, in new condition. Will include a 1link cable $320 shipped.

I use one of my Neptune Dos's for automatic water changes. The salt line got totally clogged recently. Have you guys experienced this and how do you keep your lines clear? The tubing goes into my salt mixing trash can which also has a power head in there. Both the power head and the bottom of...

Normally they are all orange, but I have one that's Red and one that's Green? Whats green or red? It appears to be performing the program correctly. Green/Red: Orange/Orange:

Made some minor adjustments on my Apex Control Panel! Just waiting on my Neptune breakout box and 2 magnetic float switches for some extra redundancy! Then I will probably end up going with the DOS.. If you have one installed on your system, let me know your thoughts on well you like it for your...

Hello R2R Community, I've been a member on the site for a long time, spending hours on the site to learn more about this hobby we all love. Thought it was time for me to contribute as well, so I thought I'd start with a build thread on my new reef aquarium. I set this system up in October...
