I got two boxes with a free ten gallon. I am wondering if this stuff works at all. It has some good claims and I believe it reduces nitrates like plants do....
i got it and there was a rip on the back so i couldnt read it
it sed 10 ML per _0 gallons kuz there was a rip so i couldnt read the first number
so i figured it as 10 and added 40 ML to my 40 gallon planted
turns out it was 50 gallons ended up killing every plant in the tank
but ya it works if used as directed
