2 teaspoons and mix it with 1 cup of drinking water.

for my 140g net, I need 9 tsp from 240 to 390ppm. I dosed 1 tsp per day, mix with fresh RO.

I wonder if this would be a decent way to supplement aspartate as well.

Any of you notice any effects on the aquarium of adding potassium?

The potassium aspartate is interesting, and any noted effects could be due to either the aspartate or the potassium (or something else in it).

Note that if you do a big potassium boost, the amount of aspartate is quite large (larger than the potassium). I'm not sure what effect a lot of aspartate might have, but when metabolized it will provide nitrogen to end up possibly as nitrate (more than the potassium dosed).

So do you think that the potassium/aspartate mixture might be a better option once K levels are already at a target range vs. a correction dosing(can it be called correction until there is more studies done) and KCl used for the larger K increases?

It might be interesting to experiment with, yes.

So far, I have noticed 4 tanks using the KCL without effects on corals. BTW, tese 4 tank mainly house SPS.

I totally agree. It's sort of a chronic accumulation. At the present everything might look o.k but who knows.

Sometimes I look into my tank, I still don't know what the heck is actually happenning in there!

At the present, would monitoring nitrate levels be the only way to keep track of the aspartate or ??

That probably won't work since nitrate is consumed as well. I'd guess aspartate to be metabolized fairly rapidly, especially as bacteria in the tank get used to finding it in the water.

Well I guess it wouldn't be much different than adding another N and C source. If I cloud up, I know it's too much!

It seems a lot of reefers using this KCL for supplement instead of Zeovit K+ balance.

I dont see why not. If it's good for human consumption, it's good for my tank. Besides, it's wayyyyyyyy cheaper.

Not to be argumentative - but a lot of reefers also are completely ignoring Potassium. IME, there's been a kit out/etc for less than 6 months ... IMO most folks who have kept SPS tanks for years are not using this [except the few that run zeo].

When it gets past a year or more - then I'll see a trend. Until that point - has anyone really had a chance to evaluate the long-term in any sense at all?

I'm still confused how we are not providing plenty of potassium in the foods we feed. IMO, it seems like that would be a fail-safe method of dosing

In the forementioned study, they did not find a deficiency so how are so many finding low K levels with the "test"?

Didn't I read somewhere that zeolites remove K from the water column. I just woke up and on my first cup of cofee so I may be way off here.

I agree that I don't quite understand it either, although I've not yet seen a detailed in/out balance study for potassium.

One of the things that I am hoping to see one way or the other is whether folks dosing potassium chloride see any change in the aquarium. So far I've not heard of any.

Didn't I read somewhere that zeolites remove K from the water column. I just woke up and on my first cup of cofee so I may be way off here.

That is a possibility, but probably unlikely unless people are constantly swapping in large amounts of fresh zeolite.

Do you feel it is an error on the part of these new tests popping up, possibly an error in the 2002 study, or ??

I don't know. I'm open to all reasonable possibilities with respect to potassium.

IMO, if you don't run Zeovit, you really don't have to worry about Potassium. I used to have NSW (or Catalina water-CW particular) for my preivious tank for more than two years, and I didn't see anywrong. Since I switched over the Zeo for new tank, somehow the K+ is really low. I think most folks those uze Zeo run into low Potassium. I tested the K+ of my friend's tank who uses CW, his k+ around 280ppt but his tank looks awesome.

Bebo, did you check you K+ again?

did you see much more difference change in K+ level?. If you dose with k-B, it takes you forever to reach 400ppt, right?

lol.. well i did raise my K+ level a little faster than you did, i am at 325/350 ( as of this morning) i dosed 4 tlbs a day for a week now and i have use 1 bottle so far.. my level used to be 250. I hope to have my K level at 400 by the middle of next week...

What are you using to dose potassium?
