HAve a pretty established 30l Biorb and have recently started to set up my new 75l tank-tiny judging by many of the posts, but until I work out what other furniture I can ditch/walls I can knock down will have to do! LOL.
Both tanks test 0 for NO2 and 3 and I have recently introduced 4 Zebra Danios to the new tank (jump started the cycling with substrate from my Bioorb), however my pH readings for both tanks is 6.4-same as my tap water and I wonder if I need to adjust this level.
My Biorb has 2 cherries, 2 neon Tetras, 2 glowlight Tetras and 3 Endlers (all of whome have been there for 2 years) and so far only Danios in the new tank.
I have to admit I am only recently getting into the chemistry aspects of fishkeeping

So should I fiddle with the Ph or not?
Thanks
