Tropic Marin Part C for trace with BRS 2 part

[Randy Holmes-Farley Verified Community Expert]

Cant imagine adding Over Half a Gallon of anything at once..
Just seems odd... but its correct...correct? .. part C... is dosed at double the soda ash daily dose. .so 180 ml a day..Ash.. = 360ml part C
= 2520 ml / week = 10.5 cups/.66 Gal
Seems so strange to call something supplemental, but then btw, the main thing you dose the most of ... double that , and dose much of this extra piece of the puzzle.

I do not know how concentrated they make it, but for sure the tank is not drifting much in a week and so from that perspective, once a week is fine.

The Balling Part C is not like other additives. It is essentially seawater without the added sodium and chloride. Thus the effect is closer to a water change than a supplement addition.

Again, though, I do not know how strong BRS is recommending the solution be made so i cannot comment on the volume required.
