Thank you for your input into this thread! Wish I would've caught it earlier. Could have saved me a few hundred dollars.
On another note:
Anyone interested in a brand new Seneye Reef? No idea if it's anywhere near accurate but it shows some numbers. If it is accurate I don't know that those numbers correspond to anyone elses reported numbers so I don't know if I should raise or lower my light intensity. (Based on the BRS AI Prime videos I've been raising the intensity 7% per week and my corals are starting to color up. If I used the Seneye readings I would have left the light alone)
