I found that earlier myself...

Very informative and I am treating accordingly ...

They are on my balcony now out of the water after having their antiseptic baths.
No more swimming till tomorrow now then back in the sun to bask.

A friend of mine has also advised me on powdered egg shells and pumpkin in their diet.
I will be acting upon this in the morning...
