Tetra aquasafe was the best selling product when I ran a lfs, mainly because it didn't last very long. If people asked my advice I always pointed them to prime which is what I used but as silly as it sounds lots of people prefered aquasafe simply because it was blue and they thought it did more.
I'm currently changing 200 Litres every other day, I would be getting through a lot of aquasafe..
Wow. If performing such large changes have you considered sodium thioisulphate as it is even cheaper than Prime, but you do have to mix/prepare the solution your self.I'm currently changing 200 Litres every other day, I would be getting through a lot of aquasafe..

We were given 4L tubs of aquasafe by the reps and I had no issue using it but have always used prime at home because its good and economical. If you are going to keep doing such large water changes you could consider seachem pond prime which as far as I know is the same product just twice (give or take a little) as concentrated.
And that's a big a big no from me....As I understand it, sodium thiosulphate will only remove chlorine. Doubling the dose will not help if the water contains chloramine. Nor will sodium thiosulphate help with heavy metals.JPC
And that's a big a big no from me....
Sodium thiosulphate reaction with free chlorine. Most common reaction is number 2 below. The residual hydrochloric acid also reacts with the thoisulphate to sodium chloride, water, sulphur and sulphur dioxide.

Heavy metals in the UK (and EU) is not an issue as very strict limits are set on the supplied water.
That is probably the compound in "Prime", Seachem won't tell you, but "Amquel" has a patent, and it <"uses this type of compound">.sodium hydroxymethane sulfinic acid"
It is a fair point, tap water has to be <"safe for human consumption">, but there aren't any other provisos.I don't think we should automatically apply those figures to fish or other organisms. Take copper, for example. In 2018, the copper concentration from my water company reached 1.02 mg/l. The LC50/96h for Malaysian Trumpet Snails is 0.14 mg/l. Those are the facts.
