LOL, thanks for reminding me of that thread.
I went through 2 buckets of Tropic Marin BioActif since January and I did loose 1 old acro colony (a 4year old, 6inch diameter nice yellow wild colony) and a purple porites. I had a minor cyano bloom.
But, I had so many system changes to mention (and many still in the works). So I cant say for sure what the cause was. I also didnt do a water change for 6 weeks, not by choice.
Anyway, overall my experience wasnt bad with this salt or TMP. My SPS and clams are still growing outta control. They need fragging! The water is so clear people continue to say the fish are floating in space.
But I'm not buying any more BioActif because I cant detect any difference to justify the higher price.
