There is better stuff out there that isn't as costly
on February 19, 2012
So, I used this initially when I first got an aquarium because someone else told me they used it. At first all was fine, it does what it needs to do by getting rid of the ammonia/chlorine from tap water.
Here's the thing, these water conditioners that have "slime coat" crap in them, the way they work is by BURNING the fish, the irritation induces them to produce their slime coat. I wasn't aware of this, but when I was using it, I noticed that some of my fish would always flash - swim rapidly up and down the glass - I didn't know if it was them being "excited" to have a water change, no, they were just in pain/stressed.
Anyway, after coming to the end of my bottle in like 1 month's time, I ordered Seachem Safe (powder version of Prime). My fish no longer flash, and it works better, way more cost efficient. Save your money, buy Safe or Prime, both are way better.
