Just Chlorine burned my entire cichlid tank

  • We are currently upgrading MFK. thanks! -neo
pour the declorinizer into the tank, then put tap water in!
 
I know this is very bad but my fish have been living in my tanks without Dechlor. Once I get a 110 gallon I will use Dechlor this time. But non of my fish have had problems with chlorine burn. Maybe you should test your parameters in case it might be bad water parameters
 
it was sort of mentioned earlier, but one thing that can happen - - our water utility does it at least 2x a year - - is they will super-chlorinate the water for a week to "flush" the system. at these time the chlorine (or chloramines) in the tap water are at much higher levels than normal.

they send out a notice whenever they do it, but it's easy to miss . . . I use R/O water anyway, so I ignore it, but in a situation like the OP described, that would definitely lead to a problem
 
before you fill the tank up next time put some prime or amquel in first.
 
Man I have read enough bad info in this thread to make me sick.

Seriously...

The other two have been addressed, but as for that post about using pure RO/DI water....RO/DI process strips everything from the water, including the mineral content. It has no buffering capacity, and the ph crashes with no resistance. You have to be very, very careful using it. Even with Discus I'd still mix it with minimum 25% (better 50%) tap water, unless you're adding buffer.

at first I thought you meant my post, in which I said I use R/O water instead of tap water, and I was going to just chime in to confirm that I always use Seachem buffers and trace elements when using R/O water :)

but I think you're probably referring to the guy who said he makes his own and just adds it directly to the tank . . . I agree, it sounds risky, maybe even reckless; my guess is either his R/O unit is not as efficient as he thinks, or maybe he does minimal water changes. could also be his tank is very well-buffered and that minimizes the impact of the R/O water

he could speak for himself, but if he's not having any problems, then good for him I guess . . .

what the hell? people uses chlorine to clean fish tanks? ill never use chlorine to clean my tank lol
no,
peoples live where the water in the tap has been treated with chlorine and or chloromines to purify and make it safe for human consumption...

That being said, I want to know why the OP was doing a 50% water change.

My suspicion is the water changes haven't been done in a while, so thinking a large waterchange would be right, a 50% one was done...

Problem is, if you do not do regular water changes, the Ph can swing due to a side effect, of the nitrogen cycle. It takes a while but it does happen.
So, here comes 50% of the tank with a different Ph, and by time everything equalizes the fish go into PH shock because it has changed too fast for them to acclimatise...

The symptoms seem more like PH issues, rather than Chlorine poisoning...

55 gallons is just enough water to seem stable but things can go wrong really fast still...
