Potassium Poll
Please reply with the potassium value you dose to, what supplement you use, and which test kit you use.
--------------------------------------------
Randy Holmes-Farley suggests that potassium doesn't need to be dosed unless Zeolites or Ultra Lith rocks are used seeing as apparently the rocks suck out potassium. I don't know what brand salt Randy uses, but he writes that his salt mixes up with 380 ppm Potassium. I have tested both IO and H2Ocean, both of which mix to about 250 ppm, which is where my tank sits without dosing. I have been dosing to keep Potassium 380-400 ppm.
Since my test kit ran out and my potassium supplement is nearly out I ponder the cost of replacing these (~$80) and the actual effect on my reef. I don't believe I have noticed any difference, but I am not sure.
What do you guys think?
