Introduction
MyReef is the new tank which is a custom build integrated into our fully renovated apartment. The tank was filled in at the end of October 2015 and is the sequel of my first Juwel Rio 180 Reef tank which had been running since September 2013. The Juwel Rio was modified in order to become a sump/refugium for the new tank. The full setup lies next to the balcony wall thus achieving proximity to the RO unit and ATO/SW containers outside.

Lighting
Using 2 Kessil 160WE LED fixtures connected to a Kessil Spectral Controller.
I have been slowly trying to increase the lighting amount supplied to the tank in order to exclude this factor in the Acropora long term health issues I encounter. I have noticed that increasing the lighting quickly causes bleaching/burnt tips/STN to various SPS. Lighting schedule has been stable since 1st April 2017. Root cause of the issue finally found on 20/8/17. The wrong calibration of the refractometer resulted in a 1.023 salinity for a long time
Current Lighting Schedule:
Time Spectrum Intensity
13.30 0%, 5%
16.00 15%, 90%
17.00 25%, 100%
22.00 25%, 100%
23.00 15%, 90%
1.30 0%, 0%
Sump/Refugium:
4 IKEA LED spotlights (JANSJÖ)
Current SUMP/Refugium Lighting Schedule:
0.00 - 12.00
