Thanks bro. But uhm...I never test really my water...at least not yet...
I'm using tap water and do 20% water change weekly. I usually monitor it based on my probiotic salt. If it has bacteria bloom after water change, means high nutrient and the skimmer will pull out a lot. But if no more blooming after water change & acros are showing full PE, means water is ok & stable. I supposed the Pro Bio F & Phosphate Minus is working well? As for ca, kh & mg, I think since my SPS are not much, maybe the weekly water change is enough to support them.
Planning to get Nyos kits, are they good?
