I don't have a chlorine tester, is there anything I can do to test for harmfull amounts of it? eg. smell it, stir it, taste it etc? I wont give you the full story but a gorgeous fish is in in danger!
 
dump a big cap-full or 2 of dechlore in the tank.. otherwise the only way to really know is to test for it. Never had a problem w/ ODing on the water conditioner.. Ever.
 
You would have to super OD to cause a problem. Prime and Amaqel say you can Dose 5X safely as long as you have enough surface agitation to keep O2.

X2 dump in prime who cares its cheap and if I had even the slightest I wouldn't test I would just treat, kinda like Gregory House.
 
Hello; I put tap water in containers and let them sit around for a few days., usualy about a week. The chlorine will become inert over this time and the water can be use to change tank water.

This has the advantage of allowing the water to reach room temperature and i avoid the use of chemicals to treat the water.

It has been reported on another forum that some of the chemicals used to treat tap water merely bind the clorine and it rmains in a form that is not so desireable. It was also reported that some of these chemicals that bind ammonia do the same sort of thing.

Chemical treatment of tap water may be desireable if the tap water has other agents added.

I have read thru some threads on this forum enough to know that there are a number of members who have adopted the use of chemicals to treat water and cycle their tanks. i imagine they will be willing to give you pointers.

I have set up a large number of tanks in over 50 + years without the use of chemicals.

You should thank God that your tap water doesn't have chloramine in it our your fish would be dead as that doesn't gas off. You should do new fish keepers a favor and add a disclaimer that says check for chloramines because your method wouldn't work for them.
 
skjl47, Many cities have replaced the use of chlorine with chlorine with chloramine, which will not gas off, and must be removed chemically.
 
I indeed did add a disclaimer about cities adding other chemicals that need to be treated. I left off the name. And yes I am lucky so far with my tap water. The best water I ever had was from a private well that could be added directly to a tank.
 
By the way, that was a very qiuck response. I figured you guys would be willing to give pointers, but the speed is impressive.
 
Not sure I get this obvious troll.

To the OP if you have any fear of it you would only need to treat once and if you had any real levels you would know it because the fish would die within 24 hours. I killed 2 tanks of fish like that by careless mistake. I added prime and turned on the water fill line, but the line takes like 20 minutes to fill up the tank. Well I forgot about it and ended up falling asleep. so basically my tank end up with 100% untreated tap water after enough of the water overflowed and used up all the prime. Next day 2 tanks full of dead fish.
