Seachem Safe Dry Aquarium Water Conditioner 250 g

This product is meant for large tanks, and ponds but I purchased it for my water change buckets. The fact that I have to measure out between 0.02 - 0.05 of a gram for 5 gallons of water is tricky. It's not terribly hard mind you, plus it's going to last a very long time. Now to the downside of this product. If you thought Seachem Prime was stinky, you're in for a shock with Safe. It has a stench like none other. The sulphur smell filled my home as soon as I cracked the seal. It's kind of like onions and sulphur mixed, and it's very potent, (think of "The Big Of Eternal Stench". I closed the container tightly, but could still smell the eye watering odor escaping the bottle. I proceeded to put the bottle inside of a tall yogurt container, and wouldn't you know it, the stench was escaping that container as well. I may just have to store it out on my back porch, since the smell is escaping both the original container and the one I put it in. It's definitely concentrated and potent as can be. Don't get me wrong, it's an excellent product, it just stinks to hight heaven. I do recommend it, and who knows, you just might get used to the smell! :-D

Always used prime and the stuff is great but seen this was a more concentrated version so it last sooooo much longer! I purchased a set of spice spoons to make the Mesurements accurate and easy peasy. I'm not going to take a star off as the product is really cheap for how long it lasts and does what it supposed to but my good god it f&%@£#g stinks lol.

I was originally using Seachem Prime to treat my aquarium water and then reading some forums I discovered Safe and decided to do some research on this. It's essentially the same product as Prime just in dry powdered form and more concentrated so you save money in the long run. This product should last me years even with weekly water changes.
I have a 30 gallon tank so whenever I do a water change I usually siphon out about 15% of my water. I then put the dose of Safe into my tank as my bucket isn't very large. If you are changing water in a larger tank, you can also treat each individual bucket as you want but I find it easier to just dose the entire tank and then start adding in the new water after making sure it is the same temperature as the water in my tank. This is especially true if you are using a siphon that hooks up to your sink or hose for quick water changes.
I follow the instructions from Seachem's website:
Directions for all other sizes (this is different if you buy the 50g or 100g sizes!)Use 1.25 g (1/4 tsp.) for every 1,250 L (300 gallons) as needed to reduce chlorine and chloramine or use 1.25 g (1/4 tsp.) for every 300 L (75 gallons) for ammonia.
Since my tank is only 30 gallons I use (1/10) of that dose to treat the entire tank. That ends up being 1/40 of a teaspoon so I had to buy some smaller measuring spoons. I use 1/32 of a teaspoon and have seen no ill effects with using this slightly higher dose as you would be using more for ammonia anyways.
I've been using Prime for years and now been using Safe for over a month and have had no issues with my fish and chlorine and they seem very happy and healthy. You can also double or triple this dose in an emergency if you and need to quickly detoxify nitrites and nitrates.
