WebThe number of crystals increased in response to the volume reduction. In solutions without dU, 100 or more crystals with a diameter in the range 2.4-45 microm were observed already at a volume reduction of 40% when the initial pH was 7.28. For solutions with a pH of 5.80 and 6.45 the corresponding values were 60% and 80%, respectively. WebSafe and unsafe aquarium rocks.
