Would You Use These Dechlorinators?

No, it's a bit hit & miss dosage wise
I'd rather stick to a brand I know

Of course I would, it's so cheap and easy!

Go on your water boards website, find out your chlorine concentration in Mg/L, *by 1.5 as a safety net, then multiply this value by 10 to find out how many grams you need to neutralise 2000L of chlorinated water, then obviously adjust according to the amount you need to dechlorinate. That is of course if you choose this one: http/www.ebay.co.uk/itm/1kg-Pond-Aquarium-Fish-Tank-Dechlorinator-/260853361177?pt=UK_Pet_Supplies_Fish&hash=item3cbc126a19#ht_2009wt_1037

Here's an example, my water supply: 30Mg/L of Chlorine *1.5 = 45Mg/L *10 - 450 Grams treats 2000 litres so the 1Kg tub will treat 4450 Litres.

the only thing is it doesnt say anything about chloramine...

Sodium Thiosulphate neutralises Chloramine

 

[mrvillicus]

well it does, but only a bit, check this out...http/forum.practicalfishkeeping.co.uk/showthread.php?p=29232

It fully neutralises the chlorine constituent of chloramine, the only problem is you're left with the amine ion portion which forms ammonia ultimately, so if your water supply contains chloramine and not chlorine then yes it is worthwhile investing in a dechlorinator which deals with both, if your water supply contains only chlorine then use Sodium Thiosulphate, though saying that I've been using it with my water supply for years and I've never had a noticeable reading of ammonia after doing a water change, any remnant ammonia would soon be processed by the filter bacteria.

ahh super my supply does not contain chloramine great news no more wasting money on aquasafe wahooooooo

Sodium thiosulphate is the active ingredient in Prime. Why would I trust Prime and not trust its active ingredient?

Sodium thiosulphate is not the active ingredient in Prime, it is a complexed hydrosulphite salt, so is probably something like sodium hydrosulphite.

I've noticed that in several posts you claim that all dechlorinators are sodium thiosulphate based and that's very much not the case, with the minority now being sodium thiosulphate based.

The mechanism for the reaction is more or less the same though. Sodium Thiosulphate has a much longer shelf life too compared to Sodium Hydrosulphite. It is unlikely to be Sodium Hydrosulphite anyway as that would deplete the Oxygen.

My local water supplier doesn't dose with chloramine, so I fill my buckets and circulate the water over 24hrs with a small heater in each. Then I use the same power head to pump the water in after cleaning the tank........... Never had a problem.

True, but that's not the issue here.

It is unlikely to be Sodium Hydrosulphite anyway as that would deplete the Oxygen.

It's for that exact reason that Seachem state "If temperature is > 30 °C (86 °F) and chlorine or ammonia levels are low, use a half dose."

With moderate levels of chlorine, chloramine and ammonia and as long as you don't severely overdose, oxygen depletion isn't an issue.

 

[kcartwright856]

I trust Prime and I fully endorse Seachem, therefore I "sponsor" them with my money.

So, to the original question, no. I would not use those dechlorinators, or any other dechlorinators.

bet you didn't know you were opening this can of worms eh mrvillicus
