Ok, I must admitted I made some mistakes while dosing cos I didn't go thru the full manual. I didn't shorten my lighting period, remove my activated carbon, off my gfo reactor on the first few days of dosing as recommended. I also dose at the wrong timing, did a wc & dose my daily trace elements. Dosing need to be after lighting period, no water changes and no dosing of trace additives. Or else it will render the algea X less effective. I almost at the end of my dosing cycle. Having stop a few days at the 21st day now into the 14th cycle. Almost all my bubble algae gone, only left some small patches of bubbles algae and hair algae near the overflow and dt inlet pipe that refuse to go away.
As for side effects, it said to harm inverts like sea urchins & clams & I did lost a mini clam suddenly after dosing a few days later. It do put corals into a little stress but won't kill them. Do go thru the manual first if u r really serious in using it as ur last resort. It said to be most efficient in killing dinoflagellates. For my case, bubble algaes is no1, rest r neomeris annulata, bryopsis and gha. All these are greatly reduced to almost zero now. Rest that still growing as mentioned above. Need to manually removed as much as u can during this period in order not to cause any nutrient spike due to dying algae.
Hope I've answer all ur queries, bro.
