I just got this tank, and it has green circles of some sort of algae growth, should i scrape/clean this off before i fill it it with water and livestock? if so what should i use to clean it with?
Yeah you should clean out the tank before you add water and livestock. You could clean it with vinegar and if the tank is glass scrape it off with a razor blade. Then rinse the tank very well, preferrably in RO-DI water.
