Get some siamensis to rid the algae. Also, if you are dosing everyday with
fertilizer I suspect thast you are providing the algae with what they need.
You might try reducing your lighting cycle to 10 hours. I recently had a
_terrible_ algae problem. It was a new plant tank and the algae was
everywhere. I added SAE's, reduced the light cycle, and stopped
fertilizing. The algae problem has subsided for now. I only dose when I
feel that the plants are in need. I gained this piece of knowledge from
reading the multiple posts of Karen Randall. One needs to look at the
plants in terms of their growth needs and understand what they are visibly
telling you.

Possible _over_ fertilization.

You need more light for maximum plant growth; i.e., 2x's the tank gallonage.

My initial error too. Plant _dense_; i.e., 75 % of the total bottom area
should be covered.

Is the bloom white or green? If white - wait for a week - it will clear.
If green - ask someone else because I have never had this problem.
Hope this helped.
