High nitrates :(

[Wayne]

Live rock is the type of natural filtation that will convert ammonia to nitrite and then to nitrates. The only way to reduce nitrates is by water changes (10% weekly or 20% biweekly), nitrate absorbing material or N/P pellets; the first being the recommended way by most.

What size is your tank? It does look like you need some more live rock, usually 1lb per gallon is suggested
