Re: Fishless cycling - numpty strikes

no problem, oh I realised I didn't explain why I asked about the ph.
If the PH shifts dramatically the bacteria could die back. (There are several different strains of the same bacteria that thrive in differing water conditions) and sometimes the biological processes in a new aquarium cause rapid PH fluctuations especially in soft water areas where it can become too acidic to support the bacteria (if you're kettle doesn't scale up with tap water then you're in a soft water area)
Looks like your water is alkaline and thus probably quite hard so you wont have to worry about this.
As a related side note, knowing the PH and hardness of the water is quite important for your selection of fish. Neon Tetra and Corydoras for example thrive in soft acidic waters where as most livebearers like Molly, Guppy and Swordtails like harder waters. By selecting fish that are naturally suited to your water conditions you can improve your chances of success and the long term health of your new pets
