No iron readings
I have a 46g bowfront tank that holds about 35g of water after gravel, rocks, etc...
Currently I am using the Seachem liquid 1% Iron product.
"Flourish Iron™ is a highly concentrated (10,000 mg/L) ferrous iron (Fe+2) gluconate supplement"
Using the Seachem Dose P calculator only 2.8mL is required and the bottle label recommends 5mL/50g. I have increased the amount I feed to 15mL almost every other day
When I test I can not get an iron reading free or chelated of any sort. I do not know where it goes?
There must be enough available since my plants do not show and signs of deficiency.
Is anyone else experiencing this?
