Love the product
Love the product. Sadly it's quite difficult to use on my smaller tanks due to the small amount needed for large quantitys of water. Great product

I've been in the fish hobby seven months was buying 3 products every month with Prime only one it goes a long ways
I was purchasing three other products every month been using it for three months now,it goes a very long ways I still have plenty left but want to make sure there's always some on hand.A Good idea is to get a bottle with a dropper in it when doing water changes if using a gallon bucket when siphoning your aquarium for each gallon of water you add to your bucket add 2 drops of Prime.for example 4 gallons of water 8 drops of Prime 2x4=8,one gallon of water 2 drops of Prime 1x2=2.I didn't know how to do the conversions of ml went to Seachem Prime Website sent a messages to their support they made it easy for me;it goes a long ways.Haven't lost a fish since using Prime for four months. Great Stuff!!!
