Do any of you guys have a before and after photo of you corals? Even after dosing K will do. Please? Thank you.

Somehow I missed this. Thanks Gabe!
Now I wish I could get a decent reading on this Kz test for K+, man, it is hard to read, LOL!
FWIW, I'm not presently convinced of the accuracy of AWT potassium test results. They found every salt mix they tested to be way low in potassium, despite earlier tests that showed that to not be true. They also show a lot of tanks low in potassium, when previous tests have not shown that. Since they seem to have had problems making suitable standards for seawater analysis of other ions, they may have a similar problem with potassium.

Did you test your K before sending it in? The reason I wonder is I get ~425 - 450 ish on Fauna Marin kit, but AWT gave me a very low number... which is a little curious considering some of the FM products I dose contain some bit of potassium chloride in them already (Min S is one, unless they changed the formula), so I have been adding small amounts of K daily... not to mention I see no signs that are normally considered results of K depletion in low nutrient systems....
I'm having a hard time believing that my potassium is as low as awt's results. Though in their favor, quite a few numbers came back spot on...

Its been a long time since anyone posted to this thread, but I saw it and decided to check mine. I use reef crystals. I sprang for the 60 bucks for a fauna marin test kit and my potassium was at 200. I used the brightwell product to bring it up to level. Will post again if I notice any difference. But on an anecdotal note I have always had trouble keeping blue sps blue.

bump of the century.. but after 3 years, what is the general view on potassium dosing?
I have never been able to grow a monti to save my life. Acro's no probs, i have rescued dozens, but monti's...aaaaaaaa:deadhorse:
As luck have it, I was given several and after starting to dose kcl.. there was actual growth
Any ideas?

I've yet to see convincing evidence that most folks need to monitor it, but kits have improved and it is easy enough to test for yourself, or dose for yourself and see if anything appears different. 
When I tested my tank, it did not appear deficient despite no additions ever (except possibly via normal 1% daily water changes with IO).

Yes I agree, and they may actually experience it, but I also think that, especially early on in the potassium era, some of them may have been testing with a method that led them to false low readings.
a favourite past time is getting corals that is nearly dead and bringing them back.
Nowadays they get dipped and a few days of QT, but I have often found that a bit of potassium seem to help.
Another old dead topic is salt. Have been using red sea coral pro and has had numerous problems with first Mg being too high, then too low, now Ca is extremely low.
Tank is looking good though. Rescued several corals including a rather large stylophora that was peeling off the base about 1cm a day. did the same in my tank for the first 2 days.. then i added potassium and viola.. no more. Stopped dosing potassium, lower branches' tissue thinned and growth slowed down.
Got the water tested and it was 400 ppm.
Once the happy chap picked up his corals, my alkalinity rocked up, but that was too be expected? Pondering if that is the cause of the low Ca as the alkalinity and Ca needs balancing.
Short of it, nature is amazing!

Which test kit would you recommend?
You might wait for Salifert, but I used the Fauna Marin OK:

Interested in this, feeling that based on other experience Potassium might help with coloration in depleted systems.

From personal exerience my Zeo tanks were always low on K.
My current non-zeo 120 is 3 years old, I've never dosed K and the Salifert test kit (which I hate btw) came in at 440. So I really do believe this is a specific need to Zeovit tanks only.
Of course the side effect we all seem to miss is almost all salt makers upped their K number in their salts and they come in much closer to NSW nowdays.
