nitrate help

hello guys.

i have a 180g reef tank with a 75 g sump. I've been having nitrates issues for a little while now,running at 5.0 ppm using api and now out of no where they have jumped to 20ppm!!! i have been doing water changes in 30 gallons increments. i recently did 3 water changes in a week which totals 90 gallons and it worked out pretty well but now i don't know why my nitrates are so high.

water changes are done on a weekly basis.

for salt i use tropic marin.

lights are hydra 52s which stay on for exactly 8 hrs with a 30 min ramp period.

I've been feeding once every other day due to algae growth. i feed pellets, brine and algae sheets.

for filtration im only using a filter sock(which gets replaced every 3 days due to the dirt) and a skimmer.



please share ur thoughts and let me know if you need more info in order to give me a better opinion as to what i should do. thanks.
