Taking the plunge with biopellets

I have been looking at trying the biopellets for a while but didnt want to create a issue for a tank that is getting more and more stable by the day.

I am interested to see what others have to say about the biopellets. I was told by many people the miricle mud refugium I have is snake oil but I know if I have a coral that is not doing great I put it in the refugium and within days we see an huge improvement in the coral.

we also had some issues with algae and switching to RO water solved most of the issues.
