anyone doesn't do regular water changes?

[04V10]

I do changes once a week. However, I don't have much of a bioload and I have been doing some trending for elements to see how the water reacts over the week. I'm thinking I'm going to push it to 1 1/2 weeks per water change and see what happens. Maybe push it to 2 weeks. Though I do have a clam and 2 SPS in my tank. I'll keep ya posted when I push it further.
