A little help setting up my doser........

[MMAX]

I couldn't believe my mag and calcium were pretty much right on without any prior dosing. Must be the H2Ocean salt and regular bi-weekly 10% water changes. Alk was a bit low at 5dkH. I'm scratching my head on where to start and how much each day.

"Coral Grow mixing instructions


CA
The concentration that I use here is 72gram/liter of Calcium Chloride. CaCl weighs 194grams per cup. So add 1.5 cups to 1 gallon of ro water. Do be careful as it generates heat as it dissolves so only use cold water.

KH
The concentration that I use here is 84 gram/liter of Sodium bicarbonate aluminum free. It weighs 290grams per cup. So add 1 cup and 1 teaspoon to 1 gallon of ro water. Stir this until dissolved, heating it a bit may help as well. Dont add it all at once but do it gradually over five minutes while stirring constantly.
*
Mg
The concentration that I use here is 55gram/liter of Magnesium Chloride. MgCl weighs 225grams per cup. So add 1 cup to 1 gallon of ro water and also add 1 teaspoon of deodorant free Epsom Salt.

Once you have tested your system and have the pumps properly set I would not change the concentrations of the mixtures.

For calculations I assumed there is 4 liters in a gallon."

Perfect thanks for the info.

I'm somewhat in the same boat but my dkH is on the high side & I mean HIGH ( at least that's what my test kit said)

Test your tank for cal alk wait 24 hours test again
This will tell you your tanks demands
Use this chart to find out hOw much product. Is required to keep the levels optimal then decide how often you want your doser to run (cycles) find out your dosers pump rating

Mine for example runs for 29 sec every 2 hours

I know how to figure out what & how to does, what I was asking is how much additive to add to 1 gallon of RO water to dose from. I don't want to much or to little additive in my dosing containers.

Ok total concentration of chemicals to a gallon of water is as follow:
Calcium chloride 2.25 cups/gallon RO water
Magnesium
Magnesium Sulfate 3cups
Magnesium Chloride 5 cups
/gallon RO water
Soda Ash 1.5 cups/gallon RO water

Don't go over these parameters,those concentrations will vary your dosing regime. The way I see it,I hate mixing the chemicals so why go 1/2 or even 1/3 of concentration.

Now that what I'm talking about, thanks Eli.

LOL, I knew it was more than 5 cups but couldn't remember. Thanks Elias! I add the 8 cups as my mag is already mixed together (I use a half cup to add it and sometimes I lose count )

The first link I send you to randy holmes farely told you everything you needed to know and gave you a much cheeper solution to soda ash ........
