6.0 is pretty low. There are a lot of soft water fish which will happily live in that range, but I wouldn't be looking to lower it any further.Cobesey said:The barb was chasing the rams at first but its settled now, the 20 gallon is just to get me started i kind of want to know what i am doing before spendin big bucks on bigger tank,filter and heater.
I checked my ph yesterday and it was around 6.0 - 6.2 but i put a bit of bogwood in just after the test to lower it.
