tilapia losing scales, turning gray and dying

[chrisfoerst]

So, I did a partial water change and cleaned up things as well as I could. I added some sea salt but not very much. (Maybe 4 teaspoons or so). When I did a rough calculation for my 75 gallon tank, it seems as though I should add 44 teaspoons of salt??? But, that seems like way too much. Where does all this salt go anyway. Do the fish and plants absorb it or do you have to do another water change again?

Also, for anyone who's interested, I posted a few photos of the fish.taco.ponic exhibition on my website at http://christinefoerster.com/

Hope things get better for your fish...

The folks 'down under' run 1 to 2 PPT on a regular basis. They use a refractometer to test for the salinity. I remember they did say, that plants use it up eventually.
I remeber they said, plants like strawberries and peas don't like it.


1 gram of salt: liter of water makes 1 PPT.
75 gals... aprox 289 liters
289 grams ...aprox 10 oz of salt



LOL....I thought 'fish tacos' was just an unusual name, to catch the eye and make people wonder....? But you really meant 'tacos' , as in, let's eat some...
We need a 'smile face' that is licking it's lips...

Yes, the plants will use up the sodium in place of the potassium.

I had Alaskan fish tacos at a restaurant once. They were pretty good!

Ok, thanks for the clarification and, yes, my fish seem to be doing better now.
