Doing a water change today will test.
Io reef crystals.
So i don t mess with others.

Ca 478 ppm avg alk 12 23 dkh hanna.
I purchase in the 200 gal box.
The box comes with 4 50 gal bags.
Reef crystals contains essential ocean reef elements in concentrations greater than those found in natural sea water.
Instant ocean reef crystals are easy to use and provide all of the necessary elements required for a healthy coral environment.
All my reading says alk should be ideal around 10 and minimum of 8.
Gallon of water mix as directed.
Including stony corals coralline algae anemones and other invertebrates.
Although the reef crystals solution may be used immediately we suggest aerating the water until it achieves oxygen carbon dioxide equilibrium.
I mix 50 gal.
Alk tests were performed by hanna and marinlab.
As plainly advertised reef crystals has elevated levels of alkalinity calcium and magnesium.
Anyway his test results shows the following for io and rc for the big 3 that we re often concerned with.
Instant ocean reef crystals is an enriched formulation made especially for use in reef aquariums.
Stir vigorously to ensure a good mix.
He used both triton and marinlab both perform icp oes for elemental analysis tests to characterize saltwater samples mixed to 35 ppt.
To prepare small quantities use 1 2 cup of reef crystals per each u s.
Mix reef crystals with ordinary dechlorinated tap or purified water.
To get my 1 027 salinity i add 47 gal.
Extra calcium trace elements and vitamins promote growth and support the health of a variety of corals.
Before you get ready to throw your io rc away and look for a cleaner mixing salt let me put your mind at ease.
It s not accurate enough.

I have only used io reef crystals in my marine tanks with great success.
I don t use a hydrometer to test.
Doing a water change today will test the io reef crystals before i change the water.
