Just Chlorine burned my entire cichlid tank

  • We are currently upgrading MFK. thanks! -neo
That being said, I want to know why the OP was doing a 50% water change.

I do 50% on my tanks regularly...but that being said, it's regular to prevent the ph swing.
 
'Cause it keeps the water clean...you'll find it very common on this site actually...
 
its not really necessary to do a water change. i havent done one for 8 months, i just add water in when it evaporates, i have a bgk,2 different plecos, decorus syno, roseline shark, flagtail, 2 discus all still alive and healthy with color
 
Do you by chance have large amounts of plants in this tank?
 
I'm a new user to this site... lurked quite alot but never posted until recently... and there is ALOT of good info on here (I especially like the fact that the DIY section is more than just backgrounds and stands ...) but christ there are some fools and some bad info to sift through...

Poklei, please dont tell people they dont need to do water changes. Your fish might be surviving, but unless there is alot more going on with your system, I doubt they'd be thriving... BUT, I could be wrong.. YOUR fish might be thriving without water changes, it's not unheard of ... Could a heavily stocked tank of messy fish survive 8 months without a water change? No chance.

MODS PLEASE CLOSE THIS THREAD! We have TROLLS like above trying to give BS advice and there is no value add for anyone. WC are absolutly necessary and giving advice like this just shows your trolling for a reaction. Hopefully new members won't take you seriously.
 
I think that its very important to give clear information based on experience. Large volume water changes do not cause a pH swing unless the tank is suffering from OTS. Dechlor should be used for city water (unnless you are certain they only use chlorine and the water is aged). You can double to triple dose dechlor when its crisis time. Dechlor should be added for tank volume BEFORE refilling, not just the amount removed.
To the OP, sorry for your troubles.

Ahhh duuuuh okee dokee...

Hello!! seriously?

I think I am well aware of the concept behind the
"Water Change"...

Here, let me clarify the question for the OP...

Why do you change 50% of the water as opposed to 33% of the water?

And what are you considering to be regular?, weekly, bi-weekly, monthly bi-monthly, daily, anally?

For example,
on my 225g,
I change 33%, weekly, without fail.
I have my tank plumbed to drain 90g by way of a 2" bulkhead on the rear panel.

Since I am a creature of habit...
Before I open the valve to drain my tank, I check to see that I have enough dechlorinator measured out, and ready to go.
I have my fill hose in place, and I check to see that the drain hose is not setting somewhere, I don't want aquarium water.
I even put the cup with dechlorinator on the cover I pour it through so before I can even start to refill, I have to touch the cup...

My point exactly...Large W/c's are sometimes done when they aren't done regularly and at smaller percentages. The thinking being more is better because they haven't been doing them like they know they should be.
Then the OLD TANK SYNDRONE raises it's ugly head and with a large waterchange, the Ph swing is enough to cause the symptoms the OP was describing...

My discussion wasn't going at IF they should be done, but rather WHY and how OFTEN they should be done...

Also if you do something often, USUALLY you don't forget an essential component of the process, like DECHLORINATOR?
you know, like what the OP was thinking the problem might be.
This also leads me to believe that W/C's aren't so regular, also telling me why the 50% w/c and why it is probably a Ph issue...

Who really knows, I could very well be fool of crap too, what do you think?;)
