Well for sure you have a nutrient issue, this has two effects, the red turf and yes some may be shocked at this, the higher nutrient will lead to polyp extension as the corals have a strong food source, how many know that SPS use Ammonia as a food source?

Ok so if high nutrients or at least a degree of nutrients can give polyp extension why get rid of them?

Well your not, you are replacing them with the real nutrients SPS need (amino acids and vitamins). But by removing the PO4, nitrate etc nutrients you are also removing the ones that stunt growth, stop true colouration, and importantly seed algae growth.

When you reduce nutrients using bio and bak if you do not add a food source you will crash the tank as the corals have nothing to feed on, this is where the Min-S is the building block

The bad nutrients you removed, all be it gave you polyp extension, is then replaced by a nutrient source that will provide growth, colouration and not feed algea blooms

Its all about replacing a nutrient that may give one effect but also feeds negative effects, with a nutrient that will provide sustainability.

Thanks for taking the time to do that Mike. My apology for not linking it for you.
