Algaefix experiment

[tim_s]

I am going to say, Your results are confusing.

First off before I continue as I am going to start looking at the basics you seem a knowledgeable person, which is clear in your responses. My comments are not relative to your ability to keep a tank.

Here are my questions,

1: Skimmer - describe the waste colour.

2: Nitrates - what means are you using to test this? Is your kit in date, are you insuring you are both shaking the bottles and test samples between Bottle # 1 and Bottle # 2

I am really guessing my way through this because your test results are odd. You mentioned you ran "lights out" for 10 days - Do you have photosynthetic corals?

Algae can make use of low spectrum lighting, is your tank facing a window?
