Help! What equipment is necessary for a marine aquarium and who deals with marine aquariums in Kharkiv? I have a 220L aquarium, an external filter (carbon) Tetra for 250L, an Atman pump for 400L with a filter, and an Atman UV sterilizer. I have learned a bit about skimmers; please advise which one to buy (they come in different types). Thank you all for your comments.
