do you think we are feeding the fish too much? we feed a bit of mysis and flake .. everyday.. is that too much?

Your phosphate may read Zero on a test. But as the cyano uses the phosphates to grow it will show up at zero even though you have them. Does that make sense?....lol
Its been a long day
I have also found at work that if i up the flow than it doesn't come back as fast. So flow plays an important roll.
In the end it is a nutrient issue....What are your nitrates etc reading?
