I have recently set up my first tank(96l). I have filled up with treated water and all my bits and bobs, filter and heater have been running for 4 days now, and i have introduced nutrafin cycle.i also have put in various potted plants, six of them. i have been doing tests and have a ph of 7.8. no traces of ammonia, nitrates or nitrites. i have been putting small quantities of flake food in just to get the cycle going. my question is when can i introduce my first fish and what fish would be best. how ofter sould i look at water changes and how much water? sorry to drag that out a bit, just want to make sure im as clear a possible. cheers.
