hi guys this is my frist post i was wondering if u guys ever used this amazon rain conditioner if so do u guys think it works for oscars. its says it buffers water and reduces general hardness but my ph is still around 7.8 to 8.2

hey sorry not used that before but just posting to say welcome to the forum!!!

nope never used it. there are a lot of products that say they help or make water better for your fish. most of these products are not that good so watch out what you buy, you could end up wasting your money.

bog wood may help. what are you using for substrate?
