Need some advise here..
i have dose some Calcium Carbonate into my tank and the tank become very cloudy...
is it normal?
Any method to dose Calcium Carbonate without making the tank so cloudy?
Biollante;54132 said:I do use Plantex CSM+B, chelated iron 10 & 13% ETDA as well as 13% DPTA and I have not noted any cloudiness attributable to the iron or chelating agents in tanks with KH ranging from less than 1dKH to over 15dKH

I have been using the different types of iron chelators to see what happens. There had had been a lot of talk about precipitates and how long the iron remained effective with various types of chelators. I also tried iron gluconate.
So now, I have a bunch of 10 & 13% ETDA and 13% DPTA. I generally add iron to CSM+B something like one part iron to three, four or five parts CSM+B. Sometimes I just dose iron separately.
I find either ETDA or DPTA iron chelators work well. If you have higher KH then the DPTA is probably the better choice. I cannot say I have noticed a difference, though I am a Nutrient Type, so it may just be that I keep the levels so high that it make no difference.
Why adding CaSO4 to aquarium? Please, I don't know, that's why I'm asking..Thanks for answering
I am reluctant to say iron will not cause cloudiness, simply because so many have said it does.
My experience that includes trying combinations is chelated iron does not cause cloudiness, certainly nothing in the 0.5-2ppm range that most aquarists use.
Perhaps above 12-dKH and over 10-ppm Fe 2 EDTA, it is possible I have seen some short duration cloudiness though I am not sure. Likewise, I have seen short-term cloudiness when using a Seachem product in high alkaline water that seemed to briefly cloud, almost smoke-like. However, that was before I was really paying attention to the precipitate.

But then I not very sure on the amount to use for my 55 liters tank. So I use 1tsp mixed with 250ml water and dose 5ml into my tank alternate day.
Water get cloudy soon after ....
May I know the correct dry dosing amount if I using ferrous gluconate in 55litres tank??

your problem (apart from KH from CaCO3). I've never used it though.
Do you need to increase KH?

We add Calcium to raise the general hardness. Calcium is important for the health and well-being of our plants and critters. :gw
Calcium sulfate, CaSO4 is popular because it is cheap and readily available.
