I think these’s are points worth mentioning.
1) If Marineland recommends mixing “In order for the Salt mix to register normal calcium levels you need to use the entire contents of the salt mix purchasedâ€Â, then why do they tell you
“Note: 1.4 lbs of Reef Crystals is formulated to create 5 gallons or saltwater at a specific gravity of 1.021.†and also give instructions
“Note: To prepare small quantities, use ½ cup of Reef Crystals per each U.S. gallon of water.â€Â
Yet no where do they state to get the correct levels you must mix the total product purchased? I do understand items settling out due to shipping and each items individual weights, but it should be close or either the top or the bottom of the mix should have a higher level of something. In this case Ca.
2) As far as what level we should expect from RC in regards to Ca. Although they do not list the exact amount on the product they do state “Formulated specially for use in reef aquariums, Reef Crystals contains essential reef elements in concentrations greater then those found in natural sea water†and “Extra Calcium to help ensure the growth of large and small polyp stony (LPS & SPS) as well as coralline algae.â€Â
Yet here they are stating that mixing the entire product should give a reading of “400ppmâ€Â, is not above the normally quoted 410ppm. Also with the statement of “A 50 gallon bag of Reef Crystals mixed with 50 gallons of dechlorinated water, will have a calcium reading between 350 â€"œ 450 ppm.†That tells me that it is a crap shoot if you will get the 350ppm whenever I buy RC or will I get the 450ppm(which would meet their clam of “Extra Calciumâ€Â
I know this is not a DFS issue but I feel these are point that should be expanded per their marketing claims on their product.
