It is hard to understand your question. EDTA is used to stabilise PH in larval culture of shrimps and thus maintain diatom blooms, but not for "hardness" of water in culture ponds (as far as I know, but I may be wrong). Please be more precise with your question.

EDTA is chelating agent it has heavy metal binding properties and able to detoxify the metal toxicity. Farmers believe that metals contribute to increasing the hardness instead of divalent cations.

I have also applied EDTA for reduce hardness but cant able to get satisfactory reasult.

sanjeeb kumar pradhan , thank you.
Hardness result will not change . . . Application of EDTA may act on shrimp . . Relieving from hard water stress for time being. This statement I am recording here because . . Some farmer using EDTA at moulting days, and see some positive results like moulting and recovery.
The mechanism I don't know. I have started this discussion to know more field results from various region , on EDTA application and positive outcomes. I won't prefer to use EDTA . . . now I may try it. . With various dosage to see the positive in using it.
Thank you

Practically we are not using EDTA , we are doing
Organic culture, there is no requirement of EDTA, SANITIZERS
24 de junio de 2019
Yes, some of our formers used EDTA at the time of moulting, hardness, they are got good results

garuku govindarao . . Ya. . . scientifically high pH is required for EDTA reaction with solutes in water.
So aquaculture ponds usually having the between 7.8 - 8.2 at morning time.
I want to know that, is there any positive results based stories available in the field.
On
Using EDTA in the hard pond water, brings some positive signs
( elieving stress due to water hardness) in the shrimp behaviour.
Thanks for your inputs and interest.

Yes in vannamiculture
EDTA useful for reduce the hardness

Edta can help moulting of hard cell shrimp

Yes ,Edta reduce hardness and it helps at moulting stage

To my knowledge, EDTA will soften the water upto a certain extent. In a hard water environment, shrimp outer shell will get harden and face the difficulty to moult. Hence, by applying EDTA, hard water gets soften and in turn helps in soften shell and moulting process. This might be the reason farmers will apply EDTA in thier ponds during the moulting period.

EDTA also promotes good alkalinity in pond water which helps in to promote plankton growth. plankton growth might help availability of natural food tin ponds to shrimp and initiate growth.

What are the uses of EDTA and SODIUM THIOSULPHATE combination in aqua vanamei culture ponds?
13 de marzo de 2020
Yes edta can reduce the hardness in shrimp ponds with high dosage like 7 to 10 kgs per acre depends upon your pond condition.

Instead of EDTA what can we use

What is the natural remidi for free moulting

How we can control the running mortality

What can I do for not drop PL survival at the time PL pore in the pond
7 de agosto de 2020
EDTA drop the survival if we use, is it correct?
7 de agosto de 2020
For getting survival What can I do before and after stocking the PL

EDTA drop the survival if we use, is it correct?
