Hi, I was wondering if it is absolutely necessary to use water conditioner if I let the water sit for a few days? I'm housing Arowana's and read that most chlorine will evaporate, but some water systems have other chemicals that don't evaporate. I'm wondering if anyone just lets water sit without using the chemicals? I can see this saving money in the long run, plus exposing the fish to less chemicals which would be great.
 
Chloramine would be another problem. Can't hurt to add dechlorinator to bind the chloramine. It is unfortunately not a gas compared to chlorine hence dechlorinator will be needed.

:iagree: If you are using they city's water, I wouldn't risk it. Most likely it does have chloramine and that bottle of prime is definitely worth the money. You're paying for peace at mind knowing that your fish are ok after a water change. I would never skimp on dechlorinator unless you use RO or well water and know exactly whats in it.
 
Wouldn't chance it with my fish. Definitely not a place to be cheap. If you want to save money and do lots of water changes, get the conditioner for ponds. Same thing, higher concentration.
 
I used to have bottles of water sitting around and rotate them weekly for my water changes. Trust me...the bottle and a python is well worth it. Prime is pretty strong so depends on how big of a tank you have, a 16.9oz bottle can last you awhile.

no offense, but i have no idea what you just said!
 
Is there any side effect on fish if you add a water conditioner to a water that DOES NOT contain chlorine or chloramine ?

I do use water conditioner because i am fairly sure our water contains something, but i was just wondering ...

No, Ctoychik. There isn't any side effect from the use of dechlorinator whether your source has chloramine and/or chlorine, or not.
 
the label on my water conditioner actually states that the product is actually benefitial to the fish. Is it true?

that is why (one of the main reasons) i actually use it ^^ I don't use water conditioner for my bigger tank (3x2m) ... i just install a drinking filter at the end of the tap.

:grinyes:

1. Depending on that brand, it eliminates chlorine and chloramine.
2. Eliminates heavy metals.
3. Ensures slime coat production for the fish.

Either way, it is optional. You don't need to use it if you know your water is free from chemicals, etc that would harm your fish.
