1. 2x250W phoenix 14KK + 1x150W BLV 20KK. Photoperiod 250W = 10hrs/day 150w = 12hrs per day.
2. Tank turnover 3x 6100 tunze. Running in pulse mode every 5 sec. Channel A (2x6100) 40-100% channel B (1x6100) 50-90%.
3. Return pump:resun MD40 driving chiller back to sump + oceanfree 9000 (will be replaced by red dragon soon). Est total flow ard 5000 l/h after head lost.
4. Skimmer: Barr Aquatic systems SK6000 (now known as SK5200) dual beckett driven with MX70.
Water Parameter:
1. NH4, NO2 never measure.
2. NO3, 0.2ppm (last measured one month ago) now should be higher.
3. PO4 zero
4. Ca: 400ppm
5. Kh 8 dk.
Both Ca and Kh keep constant by reef manaic CR (tall version).
Rowaphos and GAC in use with OTTA fluidized reactors.
temp: 26.8 to 27.6 degs C by Artical 1/2 hp commerical chiller.
No ref in use.
Mh light is 5" from water surface.
By rockwork tallest point is abt 6" from water surface. The SPS are between 5" from water surface and 18" from water surface.
When my AT stablise down more I will try to shift the rockwork higher so the SPS will get more intense lights and hopefully color up more.
