non-iodized salt n more

ok i have a few questions. now i have heard of people using NON-IODIZED salt for brakish water tanks. however i am not using that in my tank was inquiring weather or not it was suitable for a marine tank. I used the non-iodized salt for brakish and my cichlid tank but as we know those are alot differnt then the marine-saltwater. ok that one outa the way.
2nd.. im retarded lets face it. my amonia test kit goes from 0.0 to 8.0 now the retarded question here is i tested this morning everything but the ph i do need a new test kit for that. i tested 0 of nitrites and nitrates. but amonia tested at 2.0 is this bad. considering i know we want it at 0.

i do loose alot of water in my tank not from leak but by humidity. i am no longer running open top i built me a nice canopy( wish i new something bout electrical wiring) woulda looked nicer. SO THE 2 ?'S ARE. WILL NON-IODIZED SALT work for the aquarium and my amonia test is 2.0 is that bad.

 

No, do not use that salt in your reef tank. If you want to go with something other than store bought, use Frank Millero's formula for mixing up your DIY salt.

For those who are interested, the following artificial seawater recipe is taken from "Chemical Oceanography" by Frank Millero. It makes a recipe that matches 35 ppt seawater in terms of major ions, but does not try to match all minor and trace elements, most of which will be present as impurities in the major elements.

I have taken the four top chemicals and I use that to make my DIY but I mix it mostly 50/50 with IO.
MY HOMEMADE SALT WATER FORMULA

makes approximately 32 US gallons at 1.026

2240 grams of Sodium Chloride (Crystal Plus water softener salt)

1152 grams of magnesium chloride hexahydrate

401 grams of sodium sulphate anhydrous

160 grams of calcium chloride flake 77%-80%

10.8 grams of baked baking soda (1 hour at 300 degrees F)

As for the ammonia reading, if it is accurate, then you have problems. A reading that high is very bad.
I would verify the reading by having someone else test the water with a different test kit, the sooner the better.
