Potassium - Who cares?

I rotate between h2Ocean and reed crystals. I hope I'm using the right salts

No, you're screwed. I haven't tested RC (haven't used RC in over a decade). H2O is low - around 300 ppm IIRC. I add 4 tsp Brightwell Potassion to 15 gallons of H2Ocean and this keeps it up in my tank doing 10% weekly or bi-weekly waterchanges. Give it a shot Kien! You will only see a difference if it is and has been low for awhile (obviously).

Well now you've got me thinking about potassium.. And here I was sitting in blissful ignorance. Thanks Mindy! Or should I be thanking Brad?? It's a conspiracy!

Doooo it! It's not like it's expensive or difficult.

All I can find on the web tells me natural seawater is about 380ppm

A testing problem I have is the Elos turbidity kit has a small range between 300 and 400, so it's near impossible to tell what the results are, and this leads me to believe it's not worth dosing as maybe I'll add too much and upset my critters

I'm with Brad and others ... frequent WCs and ignore the K issue altogether

After all the input, I've decided I still don't care. Just looked in tank, it all looks fine. Think I'll just sit and watch it instead of mucking around with it.

Well, according to the poll the overwhelming majority of canreefers agree with you. That or they don't know what they're doing..

You can't do that ... you still have to go tweak your Ca reactor, and move some SPS around, and tweak the skimmer too

I think you have enough mucking experience to know what's best

I have this kit. It's pretty easy to use. I always use it under the same bright white fluorescent lamp so I have good, consistent lighting. It's quite easy to tell the difference between 300 and 400 ppm. I'm confident I can use the kit with +/- 15 ppm.

FWIW, my maintenance is about the same as all you guys. I test SG, Ca, alk, Mg, K once a month-ish, and it takes maybe 15 minutes because I have them all going at the same time. NO3 and PO4 maybe quarterly just for interests' sake.
