Python Syphon....how To Get Right Temperature

I'm not saying it can't be done, it's just that it's probably more cost & time effective to use a good water conditioner. I'm sure if you look hard enough, you will find someone who says boil for 2 minutes & it's good to go, another will state that boiling for 2 hours is the minimum. This is typical for aquatics.

I don't think some scientist or water company is going to compensate you for a tank full of floaters. Water companies are constantly adjusting the amount of chemicals added to compensate for seasonal fluctuations, as well as other localized weather events. They don't inform you of their daily activities, the most you can get is a yearly water report, which is for the most part yearly averages, with highs & lows. It's up to the lucky aquarist to try to figure out when & why they adjust their added chemicals.

I would rather err on the side of caution & use a good water conditioner. Besides taking care of chlorine & chloramine, they bind any metals that may be present weather they come from your plumbing, or the water supply itself. A 500ml bottle of Prime treats 5,000 gallons, and costs less than $10. Figure out your fuel cost for boiling that amount of water for whatever time you think is needed. Toss in the time involved boiling 5,000 one gallon pots, or 1,000 five gallon pots. I don't consider that effective, taking into account varying opinions on the effectiveness, time involved, and cost.
 
It would probably be cheaper on a larger scale to use a dechlor but that will leave ions in the water and there is a belief (though I do not subscribe to it) that an overdoee of sodium thiosuplhate (one of the more popular de-chlorinating chemicals) can lead to a lowering of dissolved oxygen levels. One should remember that since the de-chlor instructions on dosage will have an error margin, you are likely to always be overdosing to some degree or another.

The ability of water conditioners to remove heavy metals will depend on the chemicals used, and the below thread was unable to come to a satisfactory conclusion over exactly how the products do it (it seems some may actually be lieing about how effective they are). It turns out that some water conditioners do not pertain to be able to remove heavy metals, whereas others with the same ingredients do.

It can be less than wise to just throw chemicals at your tank because of what they say on the side (just think of cycle...)
 
I agree that it is totally unwise to just toss chemicals at the tank & cross your fingers. I have also heard about O2 reduction with sodium thiosulfate, and think that it may have some effect with a massive overdose, but when normally used any O2 reduction is so small as to be not worth worrying about.

In the case of sodioum thiosulfate removing metals, it does do an incomplete job. EDTA binds them better, but neither actually removes them, just binds them into a state that is harmless to your fish. The hows & whys, as you stated, are another long scientific research debate. Welcome to aquatics, the world of maybe/mights. :)

I would bet 99% of the people who buy aquariums don't do anywhere near the research we do andywg,a lot of these are the toss chemicals & pray folks, and are the main reason aquatics equipment is found for sale cheap at garage sales & such. The best thing you can do for your fish is research.
 
Hiya cheffi. If you are planning on keeping cichlids, which is what I am pressuming, due to you contributing to the cichlid posts and asking questions, why dont you just fill straight from the cold tap? as long as you run the water as slow as possible as not to cause too much of a drop in temperature, too quickly!!! most of us you have spoken to use the same method without any adverse effect. there is a thread there that was started not too long ago with regards to water changes, and how we all do it, this was with regards to the African cichlids :D :good:

And stress coat seems to be the more favourable declorinator, but dont tell mama, you'll set her off on one again :lol: :lol: :lol: :lol: :p
 
Cheers brewyn, I will top up straight from cold water tap as you say. I have used Tetra AquaSafe and til I finish that bottle I'm not going to change it but I'm thinking of going over to Seachem Prime.
