Just to chuck my 2p's worth in Jen.... I personally wouldn't try to adjust pH and KH etc... It's a royal pain in the butt to do & unless you have very specific water conditions you are targeting I'd consider it a waste of time, effort & money. Let your tank find it's own natural balance really and this means taking time to do things gradually... and gradual changes is the key to all this really and in a sense this philosopy has already been advocated with the suggestion of using a short initial photo-period of just 6 hours and then gradually increasing it to 8 - 10 hours.

Totally agree with you m8 im not keen on playing with water conditions if i dont really have to, but it was more from previous "fishless cycle threads" commenting on a ph crash will stall a cycle and not process ammonia, so it was more that if that can happen during a fishless cycle why doesnt it happen when u have an established tank.
