Wanting to add R.Sea K supplement

TDTA1181 · Jul 29, 2015

I've been measuring my tanks K the last couple wks & noticed its on the lower end. I've been adding Zeovit K supplement but the only directions it has on the bottle is 1 ml/25 gallons daily I'm guessing this is a daily consumption dose & I've been unsuccessful raising K w/ the product. I went to LPS & bought R.Sea C.Colors B supplement for K & Boron. My current measurement is 368 ppm and from reading the directions on bk of the bottle it looks as though I need somewhere in the neighborhood of 56-58 ml to get my reading to 395-400ppm. Does anyone have any experience w/ this product of suggestions how much per day it's safe to raise K. I've read only to bring it up 10 ppm/day? Also, I've read your suppost to take your Cal reading & multiply by .95 & that should be your optimal K reading?

Any help in the issue would be greatly appreciated, Thanks

Alk - 7.7

Phosphate - 0 ( I know, I'm trying to get some kinda reading but been unsuccessful so far)

The optimal potassium value would be unrelated to calcium (IMO). Aim for the natural level of about 400 ppm regardless of the calcium level.

If you have confidence in the kit, then raising it 10 ppm per day seems fine, but you might check you salt mix to verify the kit. Too much potassium seems to not be good either.
