I started with AWT, then I monitored myself with the red sea kit. I try to keep my salinity stable at 1.025-1.026
What do u like to keep it at randy
Following....
I also dose potassium but I struggle to get it up to the desired levels
last week I decided to make my goal to get it to 380-400.
currently its at 350-360 .
I struggle with pink SPS .I get good PE but the color is the problem
I also do a 10-15% water change every week .
I add Continuum Potassium to my RODI top up .
This wasn’t helping much so on the weekend I purchased Red Sea color B for Potassium ( i think it was B)
I have been adding this over the last 2 days.
My tank only has a skimmer on it but its full of SPS.
I am dosing the good Randy’s recipes.
Salinity is 1.025
Salt used is Red Sea Normal (blue bucket )
I keep hearing about trace elements being replaced by Calcium reactors so I have been flirting with the idea of getting one.
The other question what trace elements are replaced? Is potassium one of them?
Does anyone know if the potassium put in the RODI water used to feed a Kalk reactor precipitate out? I'm currently doing this and just realized that maybe this setup is useless.
Thank you!That would be fine.
Thank you for the explanation Randy.
So in essence if potassium is present in Coral tissue and algae. This would affect the zooxanthellae and in turn the color of the SPS.
Is that correct ?
Am I/we on the right track by increasing the Potassium to 380-400ppm ?
Funny thing is Blue/Green & purple SPS in my tank are fine . its only the Pink colors that I struggle with
Hi all
There is/was vigorous debate on this topic in the ZeoVit forums.
Many aquarists noticed, myself include, that if you had an oversize skimmer for your water volume and skimmed very wet then you would get a rapid depletion of K+ of ~20 ppm/week.
Perhaps it is being skimmed out with the bacteria (we all carbon dose), perhaps it binds to the DOC or is taken up a bit by the macroalgae? I don't know as I'm not an expert in this field, but in my sps heavy tank, with carbon dosing and a fairly wet skim, I have to supplement KCl as I lose ~10 ppm/fortnight.
The value is kept at 400 ppm measured with a Salifert test kit.
I have noticed by looking at the corals that they lose some of their "shine" when the level has dropped below 370 ppm and K+ is always the first parameter I check when this happens, however, this is just an anecdote and I haven't applied any scientific methodology to test this.
I can believe that skimmed out bacteria remove a lot, but weren't there claims that the zeolite media used in the zeovit process also bound some potassium?
Potassium won't appreciably bind to DOC in seawater.
