So back in post #10, I outlined my dosing of Vibrant to take care of Bubble Algae. I had it BAD and Vibrant worked great to erradicate it from my tank with little to no affect on corals. But after around a year, I started seeing a few bubbles growing in the cracks and crevices, so decided to dose it again. Were the few bubbles an issue? No, but I suffer from tank perfectionism syndrome...
Anyways, I followed the same dosing procedure I used before (although sped up the transition from once a week to every 3 days) and again it wasn't until I got to dosing every 3 days that the Bubble Algae disappeared. I started dosing on 02/08/2020 and completed my final dose on 03/12/2020.
This time my acros were exponentially larger than last time and I did notice some issues with certain acros. A few of my acros are more sensitive and I consider them indicators. Battlecorals Snipers Blue and JF Fox Flame both became annoyed by the end of dosing, showing some burnt tips and discoloration/lightening. I again saw annoyance in my BBEB Zoas. The rest of my corals all seemed to fare well.
What caused the acros to be annoyed this time? My personal opinion is the erratic Alk, especially during the latter part of dosing. While dosing Vibrant I saw my Alk/Cal consumption plummet, especially near the end of dosing. My theory is that in addition to the acros consuming less, the Vibrant also targets coraline algae which my tank is LOADED with. So as coraline was dying, it was consuming less Alk/Cal which further exasperated the issue. I did monitor Alk very closely during dosing and it was super helpful to now be running the Alkatronic and testing 4 times per day. Another possible issue is my speeding up of the dosing. Last time I SLOWLY transitioned over 2-3 months. This time I did the whole thing in one month!
So for those thinking to use Vibrant in their tanks, my big thumbs up moves to more of a cautionary thumbs up. I think if you have relatively few acros and coraline in your tank it should work great. If you have a very seasoned tank filled with acros and coraline, you need to be very cautious and test Alk often. Also, up the dosing SLOWLY over time and don't rush it.
But yes, it works. And it's the only thing I've found that works for Bubble Algae.
