SeachemLaboratories 075222 Prime 100ml

In the area that we live in The water is very variable. Sometimes when it comes out of the tap it smells very chloriney. Sometimes it smells peaty..One time The water came out so acidic that it killed a bunch of the fish before we managed to rescue them.This stuff really neutralizes a lot of the chemicals in the water very very well. A capful or less into a bucket of water and given a swirl will prepare the water for the tank almost immediately. Previously I had to leave the water sitting in the tank for a couple of days for the chlorine to evaporate out.Given how little you have to put into the water, The bottle lasts quite long. One bottle will last me around about 6 months for a 65 l tank. So while it's more expensive than some other offerings, it's certainly good value for money.You just have to get used to the sulphurous smell. :)

Cannot fault this product. Recommend

I have used this in my fish tank for years. It is fantastic value for money. It seems to last for years because you use such a small amount. I would recommend this water treatment to anyone.

I’ve used this product for years and it works amazingly well. Used on my freshwater, marine and pond setups and each time doesn’t disappoint.

Genuine product

Good quality prime

A must have for any fish keeper

I was worried about the reviews on here that stated the top was not sealed.I am glad to say mine came quickly and was sealed.
