Cannot be lah, with so many experience reefer, the tank is in such a sori state. Somemore little coralline algae. no offence, just speaking up my mind.
seems like u not very convince. my marine tank > 5 years old was made by them. My friend marine tank > 7 years also made by them.
Some of the "tank maker" I know also subcon the tank making to them. So what do u think...
I know how to use this pdt. But when u mix it to form a paste, when the paste touch water, all the spirulina particle gets disperse in the water column, as such, u are wasting the powder.
