I bought some of these ching mix mineral stones for my new tank set up. Any of you guys ever tried these out before. I got the idea of a flower horn site i use will remain nameless for purposes of this thread. Any ways they say 1 for 55 two for 100 3 for 150 and so on. My quistion really is how would how even tell or can you even tell by testing the water paramiters if they even do any thing or if it is just some kind of marketing scam. I through one in the filter 65 gallon tank. With roughly 60 gallons of water. Any ways i trust you guys on here more then the other sites i use. Because i have been using this site for like 5 years. Any reviews on these guys. Thanks for your time.
