AFR Powder sludge

[chimbo84]

I keep finding this brown sludge/residue at the bottom of my All For Reef dosing reservoir. I have switched from the liquid to the powder and this keeps happening. Anyone else get this?

I remember reading somewhere on here that it is iron precipitate.

I get the same stuff with my A4R. Not to worry, no impact to your aquarium. Just rinse out your dosing container every now and then and you are good to go!

How are your results using A4R?

dang yours is ALOT darker than the stuff mine usually has. I clean it completely once it empties but man that’s dark. I get a very light rust color the TM says is ok. I have been using for 2 years and I don’t remember that showing up when I was buying the liquid stuff just with the powdered version.
