I was curious if using more or less Crushed Coral (Actually using oyster grit in this experiment) would have an effect on the equilibrium over time. The old advice was always to use "one hand full".
I used 2 glasses and put 1 spoon of rinsed Oyster Grit in one and 4 Spoons in the other. I added RODI water. LEt them soak for 1 hour.
I will refer to the 1 spoon glass as glass 1 and the 4 spoon glass as glass 2.
GH and KH are reported in DKH with API kit and pH was read with PHEP 5 from Hanna Instruments.
After 1 hour
Glass 1 pH 7.7 GH 3 KH 2
Glass 2 pH 8.2 GH 5 KH 3
After 26 Hours
Glass 1 pH 7.5 GH 4 KH 3
Glass 2 pH 7.9 GH 6 KH 4.75
After 50 hours (Added top off RODI water)
Glass 1 pH 7.8 GH 5 KH 4
Glass 2 pH 8.0 GH 5 KH 4
After 165 hours
Glass 1 pH 7.7 GH 6 KH 5.5
Glass 2 pH 8.0 GH 7 KH 5.5
Conclusion:
The tests are not super accurate so this is very rough data. It appears that more CC will result in the water buffering faster which is very good. Especially if plants are eating your GH very fast or Bacterial acidification is an issue. However, it appears the stabilization of the parameters is about the same no matter how much is use.
