ok
i guess that makes sense on the test part
Now for the the stock solution mix, did i do that part right

this is in my instructions that came with the red sea pro foundation

Making stock solutions from Reef Foundation A, B & C
To produce stock solutions, dissolve the powder in RO water as follows:
reef A iam going to use 550 grams in 1.8 liters of ro water i cant be reading this right can someone explain it to me like iam 9 years old

Reef Foundation A (Calcium)
Disolve 1kg of powder into 1.8L of RO/DI water.

Reef Foundation B (Alkalinity)
Disolve 1kg of powder into 10L of RO/DI water.

Reef Foundation C (Magneium)
Disolve 1kg of powder into 1.7L of RO/DI water.

The amount of cal/alk/mag that your corals are consuming is the big question mark.

If you have lots of corals, you can test every 24hrs without making any changes to see how much they consume. If you only have a few corals, you will need to wait longer to see any effect of consumption.

Do not dose calcium or magnesium until your corals have consumed them. Once your levels are good, then you can begin dosing to maintain those levels.

If you are using a salt mix that is high in cal/mag, you probably won't need to dose cal/mag until you have more corals.

thank you so much

once i make up my batches
do i just put it into a bottle and then to my dosing unit,

Yes then spread out the amounts it doses over a photo period , I don't use that product but typically part a and part b of most dosing is done with a bit of time in between of them not both at the same time . I would imagine its the same

CaL 1030
Al k 1100
Cal 1130
Alk 1200

To give you an idea

Yes.

You will then need to "vent" the tubes by sucking up liquid from the container to the end of the tubes.

I personally like to break-up my dosages into 24 parts daily (once per hour).

so the one thats has 10l of ro water can i put the rest in a container for later use, because my bottles are only 1 l pop bottles

Absolutely.
