i have tried a few ways of getting rid of hair algae with no success, so after reading this thread on and off for a while i tried some algae fix marine at half strength on a 2 foot cube, mixed reef.
well all i can say is that it was an absolute disaster,the hair algae weakened and would pull out but the impact on livestock was devastating.
the first sign of trouble was the death of the entire cuc,trochus,turbos and hermits,at this stage i stopped dosing and started water changes,the next thing was an explosion of red cyano which i have never had before,as fast as it was removed it had smothered and killed acans,lobos and a duncan,the final straw was 2 clams one after the other
weeks later after many water changes the deaths have stopped,i still get cyano outbreaks and have to clean green algae of the glass twice a day,and the hair algae has returned
the reason for posting my experience is to inform people that if something seems to good to be true it usually is and to warn you all that this stuff even at half doses can have devastating effects on a mixed reef,it certainly upsets the chemical balance of the whole system even after stopping its use for weeks.
