it knocked my dino back greatly but I stopped dosing because I have urchins and it killed 2 out of the 3 I had if it wasn't for that it did not negativily affect anything else and I believe it would have worked for me
I used it years ago when it was called Ultra Algae-X.
I was real desperate at the time and lost about 80% of two years worth of SPS growth before the dino's were defeated.
I finally pulled the trigger on the Dino-X (Ultra Algae-X) and it did the job, for my reef.
You must dose it to a tee to the directions, your LPS will shrivel up and that is normal.
You will lose all inverts except BTA's.
I've seen mixed reviews since that time, but it knocked out the dino strain that I had.
