How to dechlorinate city water comint into my fish tank?

Question

When I clean my 5000 gal. fish tank (tilapia), I replace the water with fresh city water. Introducing fresh water into my tank has high chlorine contents. I experienced fish dying from high chlorine contents...How do I immediately/simultaneously dechlorinate city water entering my fish tank...any gadget to install "in-line" in the water hose (garden hose) to feed my tank?
Open for suggestions. thanks

Answer 1

Fish farmers use Sodium Thiosulfate. I also use it in it's crystal form. It is the main ingredient in dechlorinator but 100x cheaper. You will probably have to order it online or go to a co-op and see it they have it there.

Answer 2

If you can temporarily run the water into a holding tank of some sort, you could use the same stuff we fish keepers of smaller scale use in our aquariums! It would be better for your fish not to be running straight cold water into their tank, too. The shock of that can kill them, as well.
I know there are water filters that claim to remove chlorine, maybe that's an option to check out. Wherever you get your other supplies from should be able to steer you in the right direction. Good luck!

I would use a chemical metering pump If I was in your situation. I have included the address of one kinda as an example. You can look in your phone book or run a search to find other brands and get contact numbers.
Just type chemical metering pumps into your search engine.
You will need to talk to a sales rep. to discuss your exact needs (flow rate of fresh tap water, if it runs all the time or just at cleaning time, ect).
I would set it up with a slow constant flow myself. This way you never have a build up of nitrates.

Here is that address;

Five THOUSAND gallons? That's a lot of water to treat. Put fish in second smaller tank while allowing refill water to "gas out " the chlorine by exposure to air.

Answer 5

No, until it became a daft quantity. Like 10x the reported dose or something. the only undesirable concern that could happen is the oxygen point could be diminished for a quick quantity of time. i'm specific your fish are high-quality. only be extra careful next time.

Answer 6

i use stress coat, that is good enough.

You might also want to consider this.

Getting some spare 55 gallons(in general, you can get alot larger) gallon tubs and fill them with water and a internal filter.

That way the water is more purified that going with straight tap.

U might want to also consider running a system and a UV serilizer.

How about something like this, but using the dechlorinater in it: http://www.lowes.com/lowes/lkn?action=productDetail&productId=55396-000000446-300403&lpage=none (available at Lowes)
