I figured it would be cheaper to get saltwater from the ocean as I was setting up a wild caught sea horse tank so why not get water from their home. Well anyways I saw some micro algae and some sea grass when I added this all to the tank I was landscaping the plants and pouring in the saltwater directly into the tank. Well later I found out theres a whole bunch of bugs that were in the plants.... But theres also a whole bunch of copypods in the tank I want to keep. Do I have to redo the whole intire tank? Or can I do something with out ripping the whole tank apart? Plz help....
