You may want to test Phosphate. Sounds like this tank may be new. Not sure if you performed rock curing, there is video tutorials. In short, before placing rocks into aquarium you can put them into a bucket, verify the dry rock is indeed dead by performing ammonia and nitrate tests. If rock wasn't totally dead it may have had some die off of living organisms inside the rock, and nutrients are seeping out causing algae to grow. In my experience even when a tank has zero phosphate algae can still grow. If you do indeed have high phosphate of course you will need to decrease. I suspect this will take a good deal of effort and time to remove algae.
Someone will disagree but I have with success used bleach to cure dry rock, simply be careful. Rinse and wash rock and let it dry completely before re-adding. This in my opinion. Good luck : - /
