Hey Guys,

Once l have my tank setup 200lt, l was planing to do a water change every two weeks. I was going to buy a 60lt tub with lid at a hardware store this week.

My question is: If l fill the tub with 40lt of water 3-4days befor the water change, do l still have to put water conditioner in the tub to remove the chorine and chlramine from the water?

I thought this would be a good thing to do as l can heat the water to the right temp with my extra heater and also get the ph and gh correct before doing the water change.

Cheers

I think you would still need to as chemicals would stay in water... as far as heating - i wouldnt think that would be required - as long as water not absolutely freezing..

Hey rainbowman,

I would of thought that having a different temp of water (20deg) and putting that into a tank that is 28deg woul not be good.

Anyone else have any comments on the aging of water?

If you heat and agitate the water, you will degas oxygen and CO2 with the chlorine. These are good things as the pH will rise to its natural level.

I prefer to do water changes that raise or lower water temps 1C at a maximum. The exception is if I want to stimulate spawning activity in which case I will target a 2.5C drop in water temps.

Alot of your question depends on how much water you are changing, although I think in 3 or 4 day much of the chlorine in an open container will disipate anyway, if your only doing a 20% change I don't think you have anything to worry about.

As far as temp, what Bob said is 100% true, a 1 degree change is all you should really have in the tank. If your doing a 20% wc and the new water is 4 to 5 degrees different it should only be changing the tank water by about 1 degree which should be fine.

The water will be clean from all impurities within a week & to be 100% sure, add a small box filter with Charcole & filter media. That's how i prepair the water for my tanks.

The temperature must be as close as possible with the tank temperature.

I though chloramine didn't leave the water and you had to treat it to remove it. I think I'd add a little water conditioner just to be safe. Even with well water that had no chlorine or chloramine I added a half dose for heavy metals. I've never had problems adding colder water to the tank but if your changing at least 25% and can easily heat it I see no reason not to.

Yeah, that's what I thought too, may be wrong but alway heard that chlorine would degass in several days but the chloramine wouldn't and needed water conditioner to help it. Not a bad idear to add sone conditioner and let it sit for several days. Also, If you can heat the water to the proper temp it would help.

Thank you all for your feed back.

Looks to me that there is many different opinions at there. I guess what works best for you is what you would go with.

I didnt put down more info for my question so there is it now. The tank is a 200lt, and l will be changing the water every 2 weeks with 40lt.

To be on the safe side l will try and match the water conditions to what l have in my tank. I'll add some water conditioner to the 40lt and heat the water as l do have a spear heater doing nothing at home. I guess l cant go wrong by doing this.

Thanks again for your help.

I have been storing water for more years than I can remember. I have several sizes mainly 25lt for the 5ft tank, and a 12Lt for the Betta tank.

I start storing as soon as I have completed the weekly water change. I add the dechlorinator to the water containers (Bunnings) top off and let it sit for one week. I heat it up the laundry trough to about the correct temp add a few more bits & pieces and that is all.

Near enough is not good enough, therefore good enough is not near enough, and only your best will do.

What you're asking depends solely on whether or not you have chlorine or chloramine. Ask your water department. If you have chlorine, it can be outgassed in a day using an air pump with a bubble stone. If it's chloramine, you have to use a dechlorinator that removes chloramine and it would make no sense to age the water.

As far as temperatures go and to use a heater or not, you want it as close as possible but slightly cooler is better than slightly warmer.
