Dosing Tropic Marine Part C in Frest Auto Change Water

[bobnicaragua]

I want to start adding Tropic Marine Part C to the BRS 2 part I'm dosing.

My 135 gal reef system does a daily auto water change of 1 gallon.

Can I dose the Tropic Marine Part C in the fresh salt water, (assuming I get the ratios correct)?

Yes. I assume you are not using the third part of my recipe (which BRS uses?). Don't, if you choose the Tropic Marin Part C instead.

I am only dosing the BRS alkalinity and calcium supplements, not the magnesium.

It's more than magnesium, but I understand.

One other question, following the the BRS recipe/ratio for their 2 part and tropic Marine part C:

Dose 1ml ak, 1 ml ca, and 2 ml of Tropic Marine part C.

If I'm also dosing fully saturated Kalk, how much additional part C should I dose?

None. Part C is not needed with kalk as it adds no sodium or chloride (the reason for part C is to offset that Na+ and Cl-).

Thanks Randy!

I am also considering adding Part C to my BRS 2 part, can u dose Part C weekly? I calculated that I would need to dose 1680 ml of Part C weekly (I dose 120 ml soda ash daily) based on BRS instructions (2x alkalinity dose). Is dumping 1680 ml of Part C at once before a water change gonna cause any ill effects to my tank (120 gallon)? I dont have room for another doser or outlet on my timer so Id have to manually dose. Thanks so much, any help appreciated.
