Safe, 250 g / 8.8 oz

I got a 30 liters (8.5 ish Gallon) Betta fish tank. According to Seachem dosage instructions, I would need roughly around 30 mg of powder (0.02-0.03 ml).As the dose is too small, I ended up using a LEGO antenna as my "micro measuring spoon" (Antenna Whip 8H). I used an online calculator to calculate the amount of volume of the antenna base (diameter and depth = approximately 4.8 x1.2 mm) and It turns out roughly over 0.02 ml. Which is a close amount to the dose required for my tank (I think!).I already used it few times for my weekly water change, and all seems to be going well so far. However, if you do try this, please monitor your fish for the next few hours for any unusual behaviour just to be safe.Looks like I won't need to buy any other bottle of water conditioner for a very very long time!As shown in the photo, I heated up the antenna with a lighter and bent it to make it easier to scoop the powder. Just push it in and move it till it hits the side of the bottle to make sure it fills up the base properly. I tried to scoop as you would normally do with a spoon, but it just didn't fill up completely.

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💦.

If you have an aquarium buy this. I have been buying prime forever and it’s great. However, when you have 2 monster fish tanks and 7 nano fish tanks you go through a significant amount of water conditioner. Seachem safe a concentrated seachem prime. I know my water quality it always perfect the water clarity is clear in my clear water tanks and dark brown in my black water tanks with absolutely no cloudiness. You really can’t beat the quality of any seachem products and this is no different. Extremely easy to use and my only regret is not buying this sooner. So again I say if you keep fish in a box buy this.

Works like prime, but at a fraction of the cost.

Just as expected! Noone sells it locally but I got it within 3 days when ordering on Amazon:)

If you have plants in your tank don’t get this stuff plants need ammonia to grow and thrive, it’s a natural source for the plants but it’s your choice

Buena marca. Confiable

This stuff works really well coming out of winter or until water stabilizes in the spring.This item should have an aluminum seal over the entire top and be completely sealed. Do not use this if it is not sealed. I have read about many fish deaths from this. I have been using this item for 25 years with not a single fish death from the product itself. I would also not buy this from a 3rd party. Either buy it from Amazon and sold by Amazon or through a reputable fish store or pond shop. This item should also smell bad like rotten eggs or sulfur.
