I'm currently using EI to dose fertilizers, but nearly every time I add Iron Chelate, the tank clouds. Why is this happening?

Tuesday, Thursday, Sunday
1/4 tsp Potasium Nitrate (KN03)
1/16 tsp Mono Potasium Phosphate (KH2P04)
1/16 tsp Potasium Sulphate (K2S04)

Saturday
Off

Water
RO/DI water with Barr's GH Booster

And, here's all my other details:
Equipment
29 Gallon Biocube with modified stock filtration to eliminate wet/dry chamber
https://www.plantedtank.net/forums/ta...ml#post1030524
100 watt Theo Heater
5 watt Biocube UV Sterilizer
72 watts of light (1) 6,700K, (1) 10,000K

Yes, it usually takes about a day to clear up. I purchased the Iron Chelate from http://www.aquariumfertilizer.com/.

it would be interesting to know your kh/gh and ph. i know your using ro/di water, however it may just be dissolving constituents in the water column. Personally, I would first get an iron test (I like seachem's but to each their own) and start with a basic knowledge of where my parameters are at. I would then try and lower dosages while keeping a nominal amount of Fe in my aquarium. Just how I would go about things. Hopefully someone will come up with a miracle answer for you.

Ideally, what should my water parameters be under EI dosing?

eh 0-1 ppm Fe but I sometimes od it a little bit and get 1.5-2 ppm range and everything is fine, but i dont use chelated, I use Seachem to dose mine, and Plantex to dose traces.

seachem iron. one of the few seachem products that dont run out two weeks after you purchase it. im not trying to bad mouth chelated iron though. used it for a while, and it worked fine, better perhaps than seachems, without much clouding.

Is your UV filter on 24/7? If so, turn it off for a day and try again and see what happens

I wonder if there isn't something in the water causing the iron chelate to precipitate out.

Have you ever seen a French Ninja? NO because they are sneaky.

Actually it is. What do you think the UV Filter is doing?

Chances are you have high phosphates which is causing the iron to form a prespitate

I'm only dosing 1/16 tsp Mono Potasium Phosphate (KH2P04) three times a week. Water is RO/DI with Barr's GH Booster. Should I reduce the Potasium Phosphate I'm dosing or the Iron Chelate?

hi,
i got lots of problem with my traces and iron causing cloudy water too using ei method. i no longer have this problem now

All my parameters were good for aquascaping :

750 Liters
light metal halid 450 w
gh 6
kh 3
ph 7.4 to 6.3 (morning to evening when light on)
2 Filters ok one bio one meca (fine foam and purigen)
dosing EI daily at morning with automatic pump
kno3
kh2po4
K2so4
and liquid traces that we find in france

and i sometimes had crystal water but the most time light cloudy water and cloudy water at all my water changes. (50% week)
so i was looking for bad filtration, bactérial bloom, green water but even with 18w UV, water is light cloudy.

So i stoped fertilisation macro and traces and my water was crystal clear.
Retry macro, water still pristine.
Change my traces with Fe chelated 13% and cloudy water reappears.

I've now changed all my parameters to allow my traces not turn white in the tank.

Chelated fe needs soft and acid water to not oxydised. so here are my new parameters of the tank and no more cloudy water :

GH 3
Kh 2
ph 7.0 to 6,2 begin co2 earlier to have acidic water as soon as possible
dosing macro at 12:00
dosing traces at 14:30 when water is more acidic than in the morning

The traces i use are very low cost and effective that's why i didn't want to change it and prefer change all my tank parameters.

Hope it helps
ju

You need to tell us how much you are dosing.
