[SauceyReef]

Is it safe to feed tangs fruit?!

I personally have feed them the banana and I've feed them lettuce before as for others I haven't tried

Horiba sell a digital potassium tester.
Coral essentials sell a magnesium additive that also contains potassium

I wonder if it is even my potassium causing the problem. I just like to hope it is because if not - there is nothing identifiable or that I can test to fix the problem :-( I know this happens with zoas, it is just crazy to be going through it for months with certain colonies suffering.

It’s a little tricky however since you need to make standards in the same seawater. That’s not trivial if you do not know the potassium in your tank water to begin with.
