75 Gallon Tank
 

Hi everybody!! I'm new here, and I've recently started a 75g tank. I've been running this tank for just over 4 weeks. The livestock as of today is 5 Clowns and 2 Green Chromis. The algae has started to pop out. How do I control the outbreak? Would getting cleaner shrimp work? Or even urchins?

Welcome to canreef.
Get some test kits to monitor your ammonia and nitrates. Has the tank gone through its cycle yet? Might be a little early for the fish.
Nothing good happens fast in saltwater. For now, feed less and change 10% of the water to get the nitrates down.
Post all of the parameters you can, so others can help you
