How long does it take for dechlor to kill chlorine ?

[tcarswell]

That was me, it gives a good visual indication of how the dechlorination works.

I'm just tired of this discussion so bare with me...'cause nobody cares since it create work for them...

Anyone who puts straight chlorinated water into their tanks with fish cannot identify gill burn !!! Until the fish are almost dying you wouldn't notice it.

Exactly how much chlorine gas are you willing to inhale every time you do a water change? HHmmm. Just enough to make you cough once? A little?

The chlorine burns your lungs as it does the fishes gill tissue, but it also stress' your fish, burn fins and strip mucus, if it happens minutely once, you and the fish can recover. More and it will also cause irreparable internal organ damage.

Breath it in diminishing amounts (as would happen as the dechlor works) for several minutes and have your doctor at the emergency room tell us how you feel since you won't be able to talk, as you will be just trying to breath and that's on oxygen! Do you increase the oxygen to your fish while you burn their gills? Of course not, because most don't run aeration because they don't like how the bubbles look.

If fish could scream at least some of you would change your methods.

This doesn't come from opinions, there have been many University studies done on this. Facts is facts.

If someone wishes to site a University study (not a manufacturer that sells the product) to the contrary please do.

I'm not here to debate this issue, as there isn't any debate.

I'm not here to accuse someone of being a poor caretaker, ignorance of how things really work can sometimes be blamed on advertising.
But once you have the proper data, how you choose to use it does indicate what kind of caretaker you are.

This is correct.

5 minutes is ok, 15 minutes is great.

Want to tell the class what would happen if you dump the container of injector cleaner (not the bottle with built-in fuel) directly to the injectors. Hint...It's not a pretty site.

Thanks DR joe! I was curious of this matter today as I am buying a python

So if dosing 1st then adding tap water isnt right, how are we suppose to do it?

The nice way of doing it would be to let the water sit for at least 24 hours or using buckets with using Prime of course for either way. But imagine having a 300 gallon tank, who could or would want to store 150 gallons a week of water to change their tank. I mean people could do it, I'm sure but it's literally just not practical. I'm not against you Dr. Joe or anything I beleive what your saying and all. Just for most people it's not that easy. Until alot of people start to seeing their fish dying doing from water changes it will just keep going on this way. I use the python method of dosing before and then adding water.

is there anything wrong with filling up the tank first with tap water, then adding a full tanks dose to it and letting it mix for 5min before turning the pumps back on?

Sodium thiosulphate (what's in about 90% of dechlorinaters... prime include) works instantly. It just creates a reaction that rapidly off-gases chlorine.


Ok well maybe no instantly, but it works in fractions of a second.

how long before it reaches all water is up to you. if you use a python then the agitation will make it spread fairly fast.

i agree, a chemical reaction instantly takes place in fractions of a second.. ever add baking vinger to baking soda?! it happens that fast...

I don't think all chemical reactions happen as quickly as vinegar and baking soda. Especially when two things need to bond under water. Its like Dr Joe says yes it does happen quick but the dechlorinator can only spread so quickly.

I also have a python. just add a little decholr as i go.

Some people would say a 300g tank would be impracticable too, especially if you can't support it properly...lie having a race car and running it on regular fuel, sure it will work for a while, but in the long run it causes permanent damage.

I keep over 400g of treated water on hand at all times. It's not that big of a deal.

Without fish... no problem.

With fish,,, the worst of problems.

Pay closer attention to your scenario, the vinegar & baking soda don't explode (as it would appear if it were and instantaneous mixing) they actually mix over a period of time, it's just that the mixture has a violent reaction. so bad example.

I also have a python. just add a little decholr as i go.

Re-read my other post.

People with a python could get a 55gal garbage can...use the python to fill the can before the water change (next to your tank)...add your chem's....use a powerheaed to mix that water while you do a water change. Use a powerhead like a magdrive or something that has a threaded output....unscrew your python from from the sink attachment...screw it to the power head...and fill. More steps yes...but maybe its better for the fish. Honestly I have always just aded as I go a little at a time to the area the pythong is filling in (over dosing really). Mayb I wont anymore....

No offense, but can you site one of these studies? I would greatly like to read up on the subject more from a scientific point of view.

If you would like to see how fast prime would disperse through your system use a drop or two of food coloring and watch to see how fast it gets dispersed. If you would like a better picture use a pinch of finely ground flake food. I think you will see that it gets dispersed pretty dang fast.

The milk example is a pretty weak explanation. sure it spreads slow in water with no movement whatsoever. Take two glasses half full of water for example, put in a teaspoon of milk in each and then stir one with a spoon. Im pretty sure the milk will be pretty well dispersed within a half a second in the glass with the spoon.
