What percentage water change did you do? i suspect you'll be having an ammonia/nitrite spike real soon... will probably need to keep close watch on the level, and be prepared to do lots and lots of water changes.
how long ago did this happen? if it only happened a short while ago, i doubt its an algae bloom.. the algae will need time to, well, bloom. It might possibly be due to the food dissolving. What fish are kept inside? If they're hardy, you could perhaps consider doing another large scale water change, just to remove some of the organic matter in the tank. That being said, you will still need to maintain a close eye on ammonia/nitrite levels and take action when necessary.
Good luck with the damage control![]()
