Do you know about Probiotic Systems (Bacterial Driven Systems)?
Generally speaking it's an alternative way to maintain and reduce nutrients in a system, rather than running a fuge, GFO, etc.
If used correctly, it works VERY well.
I recommend looking into the basics of these systems before diving in and buying all of the supplements. First, you start by reducing nutrients with the basic products to ULN levels (unless of course your already running an ULNS). Once you've reached ULN, you utilize Amino Acids to introduce necessary nutrients, and people sometimes utilize other trace elements, etc.
Prodibio (or any Bacterial Driven System) isn't an additive to toss into any tank for better SPS colors... there's much more to it.
