My Comment about Sulphur Denitrator : 1.Easy to setup. No special maintenance is required. Just make sure the flow rate is correct daily. 2. Without it, it is impossible to keep corels, anemones & many fishes together for me. 3. Use a cover to cover the sulphur column because some sulphur will melt and the smell is not very good (not H2S). 4. PH of output is low on my device (input ~8.1 but output ~7.5 to 7.8). But the overall PH of main tank can still keep on 8.1 without adding any buffer after 2 months. I guess the output may contain CO2 after reaction, thus PH value will be lower. After returning to main tank, the CO2 level may be reduced (may be present of skimmer, O2 disolved on water due to a large amount of air bubbles produced from skimmer [not sure] ???)
