Morning Parker,
I had to get through the 2 pages just since we logged last night. I know the guys are helping you, but I wanted to answer your question on “products” specifically.
First, your already going through process of testing ALL water sources that go in tank.
Second, What we all meant by products was twofold:
1) all equipment in DT/Sump, and to give a thorough inspection to see if anything was leaking/leaching/hair-line crack, etc. It should be part of your maintenance plan at least once a quarter (this is separate from checking things out during regular water changes).
2) all additives you put in tank. This includes, chemicals, biologicals, food, and as an example, things like a chemi-pure blue bag.
I did all this when I couldn’t get rid of my GHA effectively. It was also an opportunity for me to get to know my tank a little deeper and better understand how everything connects to one another.
This is a very methodical hobby, and for us new reefers can be hard because we put our hearts into it and the darn thing looks overwhelming and we just want to give up. You are fortunate to have this group of experienced reefers who are also friends.
Take a deep breathe, digest what they’re saying and go practice Lacrosse to clear your head. It’s been a tough week for you.
