It is so easy to maniuplate and create stability. I never have been a fan of letting chips fall. Once they are dialed in, weekly maintenance to keep correct parameters is easy. You can chose 7-8 or 8-9 alkalinity. It does not matter really.I believe this is why we shouldnt chase a specific number, more of a ball park that works for your tank. Alk kept within a certain range rather than a specific number has always been what ive found to work best.
You end up chasing numbers that someone else has but, no two tanks are the same so what works for someone else doesnt mean that you will find success. I try to run my tanks between 7-8 on the alk because that seems to work for me but some people run 8-9 and have great success.
