Bulk dechlorinator?

I am going through about half a pint of the stuff a month, and prices increased 20% just over the 7 months I've been doing this again.

Does anyone make this in large bottles?

That 1kg one looks to be at a good price point. I'm always scared with powders that some flake wont dissolve and a fish would eat it.
Is it a slower process to use than a liquid solution? I have lots of tanks to do, and a wonky back, so it takes a while already.

Looks like it will treat about 20000gals for $40 shipped.

The stuff I'm using now, treats 320gal for $2 (would be about $125 for 20k gallon)

I use Seachem Safe. It is a very fine powder and will dissolve instantly. It does not clump and I only use a tiny (a pinch's worth) for each 5 gallon bucket. It will last you for a very long time.

No, it's not a slower process and the fish do fine with it, based on my experience. I have 15 tanks and do water changes at least weekly. I have been using Safe for several years now.

If you're worried about it being a slower process, you could mix some up with water and then put it in the tanks. I do this for smaller tanks, where it is harder to measure. For example, I'll put the requisite amount of Safe for 30g in a small jar and use it on 10g and 20g tanks.

Take a look on sodium thiosulphate crystal...for dechlorinating purpose only...no ammonia remover or other bells....cheaper option

I recently switched from Prime to Safe. Safe is essentially the dry powdered version of prime. There are a few slight differences; but from a dechlorination standpoint, they do exactly the same thing and are both supposed to work instantly. The prime is a very fine powder so not much flaking or clumping can really happen; and the dosing is very very very tiny. I bought measuring spoons for fractions of a teaspoon (pinch, dash, dab, etc.) My 72 gallon tank gets 1/4 of a teaspoon if I recall correctly. I have about 17 tanks in the fishroom most of which get daily water changes and I think Safe is fantastic!

You could pre mix with some water as noted above; but dont try to store it. That is reportedly one of the big differences between prime and safe. Prime has something added that allows it to still work after its been mixed and sitting in a bottle on a shelf forever; whereas the safe somehow looses its effectiveness if mixed and kept stored.

Yes, but sodium thiosulfate for photography may have other things mixed in.

What I was getting from the old archives of the Krib was that black and white photography Hypo was pretty much pure Sodium Thiosulfate. Have they changed the formula?

How big of water changes are you doing? A 10% change on a 75g tank is 7.5 gallons diluted into 67.5 gallons of existing water. Not a significant amount of chlorine when all is said and done. Unless your water supply is abnormally high in added chemicals, a 10% water change without dechlorinator shouldn't be a problem. Unless of course you keep extremely sensitive fauna. If you are doing larger changes than say, 20%, then yes i would use a good dechlorinator or if your water contains chloramines.

I don't know - as long as it is pure sodium thiosulfate, it will work fine. However, since it is marketed for photography purposes, there might be a markup.

It may have some slight sulfur tint, as the thiosulfate does slowly break down with time.

Hi All,

Sodium thiosulfate (aka B&W 'fixer') was the main ingredient (along with some buffers) of the Water-Rite product in the 1960's (and before). I used it for all my aquariums when I was a kid. Sodium thiosulfate does a fine job of removing chlorine only. As time progressed the city water utilities started adding chloromines to the water because it remains stable longer than chlorine. Unfortunately sodium thiosulfate does not neutralize chloromines which are toxic to aquatic life. I now use Seachem Prime as my dechlorinator but will likely try Seachem Safe when my Prime runs out.

Water-Rite came in tablet and powder form
