Lupin;3183793; said:I don't see anything in your post explaining why to avoid sodium chloride however you are right in saying not to use salt unless the fish has health issues in which case, the use of salt is hereby warranted. The tannins from the leaves do have antibacterial properties and do help.
Yes, I have used salt in the past, I did have ray causalities in the past.
I then moved on to Epson salt, before finding that preventive measures like making sure the ray has sufficient mineral and vitamins supplements for high immunity and various leaf extracts, a better solution.
If sodium chloride is already added...
- I would not add the minerals and other salts for fear of an overdose. I do drastic water changes and prefer not to worry about salt levels in my tanks, when I put mineral salts. (The reprocessed pee
water in Singapore has low mineral and high chlorine/chloramine content) - I'm not sure how salt works, but if it dehydrates the ray, in the long run I don't see many ray kept in tanks with constant high salt levels thriving. I'm paranoid the ray may loses more than just water...
- If added along with chemical and anti bacterial remedies, it has caused a mass and sudden ammonia spike, from a sudden and total bacteria wipe out in my tank. I keep many rays together and don't want to affect the whole tank just because of 1 ray.
These are just personal observations, and from what I see among my fellow ray keeping pals. It's not scientifically proven or anything.
I just feel that each keeper has to custom their own system of ray keeping to cater to the different schedules, budgets and situations they are in. So besides doing water changes with clean enriched* water, I'm wary about any 'just add X' solutions.

but my next question was is there a significant difference in O2 level between 86 and 72 degrees?
