Mr. Microscope Posted October 28, 2014 Share Posted October 28, 2014 Hello All, I'm considering starting some iodine dosing. Obviously, testing is required, but I'm wondering what the difference is between 1% Potassium Iodide and KZ PIF? EVS says 1 drop/week in 20 gallons. KZ says 1 drop/day in 25 gallons. Is KZ really that much weaker or is something amiss here? I know there is a flouride addition to PIF, but I don't see that being a major issue. Thanks! Mr. M Link to comment
seabass Posted October 31, 2014 Share Posted October 31, 2014 I imagine that they both contain 1% potassium iodide. In this guide (http://www.drsfostersmith.com/Media/PDF/82122-ZEOvitFilterMedia.pdf), they recommend 1 drop per 100 liters (26.4 gallons) twice weekly. It seems to me that it would be near impossible to develop a generic dosing recommendation for iodine, as there would be numerous factors to consider (like other inputs, how fast it is depleted, consumption rates, and the efficiency of the protein skimmer). Here is an article that may or may not be helpful: http://advancedaquarist.com/2003/3/chemistry I'm in the camp of using caution with this additive, although I've been tempted to play around with it. I would consider the recommendations max limits, and would dose smaller amounts while monitoring the level via observation and testing. Link to comment
