I have been planning to get a Neptune system for quite a while now. However, knowing about Puratek is making me think I should reconsider. Many Neptune systems are pieced together frankensteins, the more brands you piece together and more convoluted programs you write the higher chance something could go wrong. (User error or equipment error) I like that the Purateks system is modular and appears very plug and play. The App seems SUPER user friendly as well. Would definitely add extra peace of mind if the monitoring system was an all in one system.
Final note: I think some serious thought is going into customer service already-- like the chemistry section of file library in their forums.
