Seachem Flourish clouding water

[holdyourlight]

I started dosing my tank with Seachem Flourish Iron supplement to aid in cheato growth. i have used it twice so far and both times it totally clouded up my water. Does anyone have any ideas as to what may be causing this?
i am running GFO and carbon, could it be not mixing well with one?

Iron can cause bacterial blooms. How much did you dose in what volume of water.

That product seems to be based on ferrous gluconate. The gluconate is a carbon source, and might be fueling a bacterial or cyanobacterial bloom. I'd find another supplement. Kent worked well enough for me.

i used one capful (5 ml) for 45 gallons of water

the cloudiness occurs within a couple minutes of dosing and lasts for a few hours

FWIW, I dose Randy's formula, which is also ferrous gluconate. Randy's formula is about 1/2 the concentration as the SeaChem Flourish Iron. I have been dosing about 5 ml. in 145 gallon of water. You are dosing about 6X what I dose. I get pretty good results with what I am dosing. I would try about 1 ml. next time or switch products as Bertoni has suggested.
