1. Water Quality
2. Lighting & Flow
IMO/ IME water quality is the most important. And to me that includes Ca/ Alk/ Mg stability in the proper range, and keeping NO3 & PO4 low. Lighting is important, and flow is important, but not more so than good water quality. Water changes fall under the water quality umbrella. Absolutely stable temps are not important, I get 3-5 degree daily swings with no ill effects.
I found your survey to be very easy to use and only took 1 minute of my time to do so

Every factors are important.
But if I have to choose only one choice, I vote for weekly water change.
No kidding. There is no what is MORE important... I feel that great water quality, stable alk ca mag and SG, strong flow, strong skimmer, feeding and water changes are all equally important. Not only that but you need to find that balance between them all to really make thing work and take off.+1 I almost got a headache reading all the options:hammer:
just so I understand, is the first number the temp swing allowed per day?
