ok. here is some feedback, first NEVER use well water. our tanks MUST have RO water. stop using well water. next, bioballs tend to create high nitrates, that is their nature to create them. From the picture you posted of your tank, it looks like you have just about enough live rock to not need the bioballs at all. Just to be safe, add another 40 lbs.
Are you running any kind of phosphate remover? algae feeds off of phosphates and you need to cut them down - a lot.
How much do you know about YOUR tank? I am concerned you have no idea about the specifics of YOUR tank. like lighting for example? Is it a FOWLR or are you running a reef? what is your fish load? You mentioned having 10 fish. I saw a hawkfish and a Regal tang in the pics you posted. What else do you have?
