Ok. Well I dealt with Hanna Instruments and they said that the device was calibrated at the factory, that it wasn't recalibrated AFTER that... Well, I got the calibration solution and calibrated it myself and it was off by not much, by .01 soooooooo, I check the levels of RO water and it's 0. I test my aquarium in question and it's still above 100 which is as high as the meter reads. The meter is correct. So, when dosing fertilizers WHILE I get my potassium down what would I eliminate from the following:
Potassium Nitrate KNO3
Mono Potassium Phosphate KH2PO4
Potassium Sulfate K2SO4
Magnesium Sulfate MgSO4
It makes sense to eliminate ALL of the ones with K in it, heh... so does this leave me dosing ONLY magnesium sulfate while I do water changes to get my potassium down?
This all has to be because of a substrate that I used. It is called aqua durt: Chemical makeup is as follows:
TYPICAL CHEMICAL ANALYSIS
component weight %
volatile free basis
SiO2....................................76.72
Al2O3..................................11.28
CaO......................................0.63
MgO.....................................2.04
Na2O....................................0.10
K21O....................................1.26
Fe2O2..................................6.51
MnO.....................................0.01
P2O5....................................0.11
TiO2....................................0.52
FeO....................................0.82
Loss on Ignition.................2.20
The other substrate I have in the sump is miracle mud with these listed, granted not in percentages of how much of each:
Aluminum, antimony, barium, beryllium, bismuth, boron, bromine, cadmium, calcium, cerium, cesium, chromium, chloride, cobalt, dysprosium, erbium, europium, fluorine, gadolinium, gallium, germanium, gold, hafnium, holmium, indium, iodine, iridium, iron, lanthanum, lithium, lutetium, magnesium, manganese, molybdenum, neodymium, nickel, niobium, osmium, palladium, phosphorus, platinum, potassium, praseodymium, rhodium, rubidium, ruthenium, rhenium, samarium, selenium, silicon, silver, sodium, strontium, sulfur, tantalum, tellurium, terbium, thallium, thorium, thulium, tin, titanium, tungsten, vanadium, ytterbium, yttrium, zinc, zirconium
Anyway, all that said, DO I need to be dosing any ferts with my potassium levels so high? The meter is right. I have read that having potassium levels this high isn't necessarily bad I'm just not wanting to add more to the situation.
Thanks for any insight here.
