Drs Foster and smith Chlorine Neutralizer vs Prime?

I have been using prime fro a long time now. I love that it has dosage per amount of chlorine which I know from local water test so I can use a more exact amount then the general label.

With that said I was shopping around and cam across Drs Foster and Smith 'house brand' chlorine remover. It looks like and has similar instructions to prime. I swear they just relabeled the prime package! but at about 1/3 the cost!

Since I'm sure most like me use a lot of chlorine remover this could be a great product. Has any one used it or know of any testing that has gone on with it to know if it works just as well? I would hate to kill my fish by using an inferior product but my wallet would like this stuff if it works!

I was doing a bit more digging and found dr foster and smith contains:

" This product contains DeIonized Water, Potassium Iodide, Sodium Hydrogen Carbonate, Sodium Carbonate and Sodium Tetraborate"

and Prime contains "Proprietary aqueous solution of complexed hydrosulfite salts"

Not that it means a whole lot to me.

hmmm I missed the dosage part I thought they were the same. yeah that makes the price point a bit different. The ammonia part I'm not too worried about, I rarely have a tank newly cycling and if I do i can steal media from an established tank.

Either way I guess I'll stay with Prime cause of the dosage. Especially as I mentioned earlier Seachem actually states how much chlorine is removed per 5ml dose and if you have a local water report you can find your average chlorine amount, round up a bit and you can be even more efficient in dosing. For me this means I can use even less!
