Safe, 250 g / 8.8 oz

Imagine a thousand flatulent pugs engorged on a feast of boiled cabbage, hard-boiled eggs and Fiber One bars. Then take the odor you are imagining and dial it up to 11. Good thing we love our fish. Incredible value and highly effective product.

Having multiple aquariums this is the best product you can buy. You will save a lot of money. A package of this will last like 5 years if you have just one aquarium no joke! I use 1/4 tablespoon for my 75 gallon aquariums with no issues. Suggestion: Get a set of measuring spoons. And Don’t smell the product you will notice when you open it.

Works well, lasts a very a long time, and it's a great value. Like other dechlorinators, it's sulfur based so it smells awful, especially so because it's the concentrated powder. BUT It's really good at what it does for much cheaper than any other product. It took me 2.5 years to get through one bottle.

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.

Sneaky this is the best amazing products for people with multiple tank syndrome. Make water in mass and so much cheaper than prime. There’s no way I could afford prime for 15 tanks.

I started out in the fishkeeping hobby using Stress Coat. For reasons of economy and effectiveness, I switched to Seachem's Prime, a much more concentrated product. Safe is the concentrated form of Prime. The jar I bought will treat up to 50,000 gallons of water. That might sound like a lot, but if you have multiple tanks like I do, you can go through it quicker than you think. Safe is easy to use and it seems to be very effective. The price may seem a bit high compared to a comparable size bottle of other water treatment, but when you look at the cost/gallon, there is no comparison, Prime wins hands down over any of the liquids I looked at and Safe is even more cost effective than Prime. The only negatives about using Safe versus Prime was trying to figure out the dosing and then finding a measure small enough to measure it. Prime came with pretty straight forward instructions. Safe's dosing is based on how much chlorine, chloramine and/or ammonia is in your water. I just treat for an "average" amount of chloramine and that seems to work out pretty well. Seachem's technical support is amazing. If you can't find the answer to your problem in the forums, just write to them and they are extremely responsive. I bought a large size of this product. For some reason, Seachem thinks if you buy the large size you don't need a dosing spoon and doesn't include one. However, I wrote to them and they sent a spoon to me, no charge. I treat for the full tank volume whenever I make a water change. I use one "measure" (the spoon they sent) per 20 gallons.

If you like Seachem Prime, get this. It's much more concentrated and better. A very small amount goes a long way.

For years I was using SeaChem Prime to treat the tap water for my aquariums. Then I discovered Safe, which is the exact same chemical as Prime, but the per gallon treatment is much less expensive! Weigh out 50 grams of Safe powder to 1000mL of water, mix the two together well. That makes Prime using Safe. 1mL of mixture dechlorinates 10 gallons of water. You can easily put this mixture in a Prime bottle and use the bottle cap to measure like always! FYI 3 drops from a dropper bottle treats one gallon of water. I use a cleaned out reagent dropper bottle from an API water test kit for that purpose. Works great for small volume water changes💦.

Ótimo produto.

As compared to Seachem Prime it takes a LOT LESS to do almost the same thing. Just a pinch for 200 litres.. maybe even less. Seachem is expensive but it gets rid of heavy metals also this one doesn't. Overall best VFM dechlorinator in the market one can say.

Declorinatore ottimo

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.
