Seachem Prime Water Conditioner, 2 Liter

I have multiple fish tanks. I wanted a lot for a little. Exactly as expected.

Sealed and in good condition

Good product

This is a must have for all aquarists! Helps with many water issues!

We use this product a lot. Finding this size was an enormous value for us. Shipped quickly. Very happy with this.

Stick with Seachem products, and all your aquariums will be better off for it

I want to rate this 5 stars. I really do. As a water conditioner, its great. Does the job very well. But I have come to find that it will bleach out any fabric it touches. Be very careful. We have a lot of fish tanks, and thus use a lot of prime. Since starting using Prime, I started to notice that some of my towels were getting bleach spots. I dont use bleach. Not even for cleaning. I brushed this off, but it continued. Several of my shirts Id had for years started having the same issue. Now permanently ruined. It was a mystery, until I connected the dots that I had done water changes in these shirts. I would wipe off my hands (which got prime and water recently treated by prime on them) on my shirt and towels. There are no warnings on the bottles that indicate it will bleach out your clothing. I have seen reddit posts where this happened and the people say Seachem told them Prime couldnt have caused it, but it does. I am now out several shirts that were favorites because of this, many of which will be costly, difficult, or impossible to replace. I have included a photo of one. You can see the bleach spots are only along the bottom where hands would be wiped. Several nice towels are also ruined. Again, there are NO WARNINGS on the bottle to indicate in any way that this will ruin fabrics it comes into contact with.

How and why is all I want to know?

I always use with my water changes and have had no issues with fish kills after.

Awesome product and a awesome price
