Seachem Safe 1 Kilo

The price on this product has risen over 40% in the last few months. Not the deal it used to be. Maybe best to search for another option at this point. Works pretty well, but dont believe the directions, you need a high sensitivity chlorine test kit to find out how much chlorine is left behind, especially when breaking down chloramine. May require multiple full doses a day apart to actually neutralize chloramine. Chlorine test kits for aquaria are useless, far smaller amounts then they can test will kill your fish. took thousands of dollars of dead koi to finally verify all this.

Goes long way, seems like its working so far.

Doesnt work instantly and not stable like prime even when dosing water before putting into tank had to use much more than recommended amount.

You cannot buy better than this, also detoxifies ammonia and nitrite for 48 hrs, a must for any fish keeper.

Great product works fast reliable for safety of your water for safety of your fish

Amazing stuff - so much better than Prime and a heck of a lot cheaper doing this way!!!!

Love this stuff, switched from prime, one teaspoon does 200 gallons, I have a lot of tanks and this saves a ton of money over using Prime, best switch ive made, thanks.

Seems to work as well as Prime(liquid form), but container even though sealed was only two thirds full. Im not sure why but I feel even though I tried to save money in the long run by getting the large size that I feel cheated that it wasnt near full. Not worth the hassel of dealing with since I am sure it will still last a long time. Just dont be surprised if the container isnt full when it arrives.

Save your self some $$ Cheaper than Prime, and WAY WAY more efficient that Stress Coat. (I do still get prime to dose my smaller tanks, this is hard to dose those)

It seems completly full (accounting for shipping settlment), but I wish there was a seal on it to make sure it wasnt tampered with. - no seal. I still have to use stresscoat+ to remove heavy metals but this will last longer than my fish will. and absolutely dont put your nose near the open container - eeh gads the smell!
