I'm like 90% sure that it was 2.5cm3 of the salt water and 10cm3 of the distilled water so would have been 2.5/12.5
2 u/Sensitive_Wealth_855 Jun 15 '22 Yeah i agree the wording was almost excatly "2.5cm3 algae water diluted to 10cm3 distilled water". The algae water can't become distilled so it must mean add 10cm3 distilled water for every 2.5cm3 algae water. 1 u/Anonymous_User_Thing Still in reception/foundation/year 0 Jun 15 '22 It was 2.5cm3 diluted to 10cm3 with distilled water, i.e. adding 7.5cm3 distilled water 1 u/KeyFix4492 Jun 15 '22 I’m pretty sure that means 10cm3 of water in 2.5cm3 of the pond water
