Instant Ocean Vs IO Reef Crystals- actual differences
2020-6-11 · There’s no reason that calcium needs to be that high, but calcium chloride would be the thing to use to boost calcium. I used limewater (kalkwasser) for all alkalinity additions, and long term that tends to boost calcium a bit. Using normal IO with 1% changed daily, that stabilized at about 472 ppm calcium.
