My first tank is coming up to a year old and I’ve noticed a weird stringy layer appear all over the rocks but mainly in the shady areas.
Some of these I know are pineapple sponges and some are hydroid but not sure what the rest are.
Any tips on how to remove it/ decrease the amount of it? Same thing for the hydroid and pineapple sponges aswell
