What is the best dechlorinator?
Exactly what the title implies. Doesn't matter how much it costs, as long as it's reasonable.
I'm not discussion about dechlorinators that simply remove chlorine/chloramine/heavy metals, every one does that. I'm talking about ones that do additional things, like enhance slime coat, etc.
as far as enhansing slime coat, feed your fish well. Chemicals simply add to the irritation to thicken not enhance slime coat. Like the stress coats. These read the ingredients are nothing but salt or sodium and to be precise about it. stress's fish enough to create a thick slime coat. Not other a good thing. Your fish have the slime coat they own because of the type of fish they are. There is NOTHING you should do to try to thicken or enhance it other than food. As an experienced aquarist you will come to realize that.
I do like stress coat for the fact that a little go a long way but there is no proof that the aloa vera and other chemicals in it if truth be told do anything.
