Water changes!

[mark]

The reason you haven't been supplementing is you've been keeping things up with the water changes, if you spread them out you might need to start depending on you tanks demands.

This is a very important consideration. If you have a huge amount of coral growth each month, monthly changes might not be enough. If you only have moderate to slow growth, then monthly might be perfect. This is where experience and getting to know YOUR tank comes into play. What works for everyone else may or may not work for you.
I did bi-weekly changes simply because I had a day off every two weeks and I had some spare time. Doing weekly could become a chore after a few years, so play around a bit and see what the tank needs.

must be nice!,

but to echo some of the remarks, I went from bi-weekly to monthly to every 2nd month sometimes every 4th, depending on my work schedual of when I was home or not. I was running hte guantlet of kalk reactor, Ca reactor, skimmer...... so I was not doing water changes fo anyuthing other than people said I should as my water was never deficient in good eliments or in excess in bad. Aside from maybe stuff we cannot measure. Do I believe in them, yes. do I think you need to do it every week/two weeks/moonth/year ect... it depends on your tank and what you have in it and what equipment you have supporting it.

My tank has been running skimerless since day one. The only equipment that's in the tank is the following: 2 Koralias, Heater and a Biowheel 300(rinse the cartridges daily to prevent nitrites from building up. Tank is free of algae, in fact it has never had any type of algae.

My corals grow, but not very fast. I would say I have slow coral growth but healthy.
