Hello would someone help me please, I have an aquarium 125 litres, which is about 7 weeks old. Inhabiting the waters are 7 very small tetra's, 4 small guppies and 3 cory's all seeming very happy. However my plants which are still growing have developed brown spots, am I right in believing it is algae? I have put some flora boost in the water. Will they recover or should I just replace them?
Thank you
Thank you
