Algae X

I can't edit the opening post anymore so the AlgaeX part is here instead.

I dosed 60ml to a 1400 litre system subtacting 200 lítres for 300 Kg of live rock and equipment displacement.
(60ml was dosed into estimated 1200l of water). This means I used AlgaeX as directed by the manufacturer.

My urchin lost all of it's spines, most of my sps corals are in the process of decay and some of the LPS as well.
The SPS corals that looked good before have lost their ability to shake off the dinos that now manage to get a foothold on the weakened corals.
The dinos (zooxanthally) inside the corals have left from their tips on some while others are mostly white, but not yet quite dead.

The coral death and decay can be traced to either the 3 day dark period after the first week, the hydrogen peroxid right before AlgaeX,
the change in water chemistry due to carbon, GFO and bio pellets to be discontiued, the AlgaeX chemical itself or a combination of the above.
The toxic soup is also very likely to become more toxic without any of these filters.

Right before using AlgaeX I popped most of the the Valonia bubbles I have, thinking the Hydrogen Peroxide and the Algae X would have an easy time hitting it hard.
Not a single bubble has perished, they all look healthy and loads of tiny virgin ones are growing where the bigger ones were burst. Large or small, not a single bubble has perished.

The dinoflagellates this chemical was supposed to take care of are doing just as good as before and there is no change for the better in appearance, growth rate, amount of debris or skimming quantity.
The fact AlgaeX has failed miserably to either push back the dinos or Valonia and to leave any visible difference. Because of this I have serious doubts of this product.
If it was not for the urchin to lose it's spines I'd think I have been dosing a placebo or snake oil.
It could be that the other helping steps reefers are asked to do are really providing the results we read about in the forums.

Conclusion.
AlgaeX is was completely useless for the dinoflagellates I have.
It was also useless for bubble algae.
The corals in the tank look much worse now than before the treatment.

This was the last realistic hope for a cure, I had, for my tank.
