How much anti-chlorine is enough?

Hi folks, I have been wondering how much anti-chlorine solution is enough for treating tap water in singapore.

I am currently using B*X**R anti-chlorine solution with added aloe vera. On the bottle it says 1 teaspoon to 200L of tap water. Seems like a rather strong and potent solution. But I usually overdose slightly just in case. Will it cause any harm to my fishes?

Also, I have recently switched from using A** Stress Coat. Some LFS uncle told me its better to use B*X**R as my tank is a 422 and requires more water per WC.

Can any bros here clarify just how much chlorine/chloramines there are in our tap water here? I'm living in AMK btw.. Really curious, thanks in advance

There have been many discussions on this issue.

Basically it should be safe to overdose the anti-chlorine solution, more importantly anti-chloramine solution.

Just follow the dosage requirement stated. I sometimes double dose.

i will dose the anti chlorine/chloromaine base on total volume of tank regardless how much % i change.

Not to worry so much about overdosing of anti-chlorine.

I do that as well. Personally i think that's the safest bet. For Seachem Prime(which i use), i will dose 1 capful each time i do a WC as i have a 4x2x2.

Thanks for the response I guess I'll just dose for the total volume of water I have in my tank from now on, even though I perform a 20% WC each time.

I was worried that the chemicals of my anti-chlorine solution would stack up eventually, just like how salt would if you keep replacing the dosage needed for total volume of tank when you're only changing 20% water.

I take it that anti-chlorine being excessive will not harm fishes.. Just that I noticed some slight foaming at the surface of my water... I suppose its the extra anti-chlorine solution I have been adding lately.

As I've never overfed my fishes, I don't think its to do with any excessive protein amounts present in my tank, am I right?

Thanks again for all the response, cheers

422 at full tank is ard 400litres plus, 1 capfull of prime only treat 200litres.
Better dose 2 capfull juz in case.

Seem many have overdosed the anti-chlorine me too. One other point is if the fishes are either small or expensive then better to overdose.
