Potassium - Who cares?

+1.

I don't think I have ever even tested potassium. I suspect my water changes keep K in check.

Depends which salt you're using.

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
