My tank is about 3 months old including cycling time. The shrimps seem to be happy, I have a population of about 15 shrimps, and now have 30 larvae with another 3 more berried females.

Problem is I have quite a lot of brown algae growing on the tank walls.

I don't plan to clean them till all the berried shrimps have released their larvae, but wondering that to do about the algae after that.

Should I just leave it? Or do I need to do something about the water quality? Ammonia, nitrites and nitrates are pretty much undetectable on my test kits and strips.

I feed my shrimps once every 2-3 days with spirulina or tiny cut up shrimp pellets.

Your tank is still going through it's cycle. That's why you have the brown algae. Let it continue to mature. Your macro algae will take up the excess nutrients over time. Leave it. Don't test. It's doing fine. The algae on the sand and side will continue to grow since you're feeding. You can cut out feeding and that would help on the algae growth.
