I’ve been curing my rock for over six months in a 100 gallon plastic tub. I have treated this as if it was in a typical aquarium to learn before setting up a complete system. No corals just fish for biom. Parameters, lighting etc. coralline has done well covering rock and sides. A few months ago noticed a lot of white specks covering everything including snails. Shortly after that a dark green hard algae like coralline began to cover everything including established pink coralline. Any advice on what this might be and any recommendations. New to this forum so hope I’m in the correct section to ask this question. Thank you in advance and look forward to learning from you all
