My water will turn more green with a good bloom rather than mostly brown. Although some blooms can be brown and/or reddish. My blooms have always been green. When my blooms go nuts, the water will be a wild green, kinda nuclear looking...
And if it gets completely out of hand it caused a surface funk...
All of the above photos are extreme events and not typical. The difference between a no-bloom-muddy-water day and a good-bloom day is rather insignificant, just a few shades of green beyond yesterday's more brownish water.
