I estimate 60G, though most would say closer to 70G. However, accounting for the glass thickness, it's closer to 60G imo.
The Orphek app reminds me of the early days of the Mobius app - crude and not very intuitive (not saying it's much better ;)). Everything is controlled by sliders, which makes getting precise numbers tricky. Hopefully, the app will improve over time.
I'm new to Orphek and its app. Although I’ve explored the features and settings, I haven’t used them in my programming yet. From what I understand, the Helius program assumes your starting baseline is 100%, with the intention of acclimating new corals in a stable tank.
Currently, I’m using a custom program based on settings from my other tank, which runs on Radions, Kessil, and AI lights. After a brief PAR and spectrum measurement with a PARwise meter, I've set my channels as follows: 100% for channels 3-6, 70% for channel 2, and 60% for channel 1 during the first half of the schedule. In the second half, I use 100% for channels 3-6 and zero for channels 1-2.
With a relatively new tank, I’m cautious about potential issues with max settings on all channels (especially on Helius mod or Sun Moon Sync mode). I also prefer less yellow in the spectrum, so I’ve chosen this ratio based on PAR and spectrum readings. Even with these settings, I've noticed that the yellow and greens are higher in this tank compared to my other SPS-dominant tank, which has been running for over four years. But since I have been wanting to slightly increase my whites, reds and green, I am going to give the high readings a try. Since the light intensity is currently only at 55% and will continue to ramp up over the next few months, I may lower channel 1 and 2 if algae becomes an issue.
For reference, here’s my current light schedule:
- Start: 13:00 – 0% all channels
- Ramp-up: 13:00 - 13:45
- Daytime (13:45–18:00): 55% channels 3-6, 39% channel 2, 33% channel 1
- Evening (18:15–23:00): 50% channels 3-6, 0% channels 1-2
- Ramp-down: 23:00 - 23:45
- End: 23:45 – 0% all channels
I’m about to activate the second Natura with the same settings and will measure the PAR across the tank.
