I have seen several people results show normal Al levels (Not high). There's been a lot of discussion about it lately ( Just ask Randy :lol: )

For what its worth, here are the results of my test as well. I had a handful of high readings. The copper is one I'm a bit concerned with. Don't know how that is occurring? Of note, this sample was sent in after I had skipped doing water changes for probably 6 weeks. I'm going to be getting on a regular schedule of once a month and I'm adding a refugium to grow macro-algae. So, I'm sure my results will change. I'll retest again in a month or so. I'm going to send in a sample of my salt water mix in the mean time to see what I'm putting in my tank when I change the water. That might shed some light on where the high levels are coming from?
