Green-ish cloudy tank? Is it just a cycle?

[Reef Puffer]

Is suspended algae. I ended up with it after i moved my tank. I tried everything for weeks! In the end, i blacked the whole thing out for 4 days. Duct tape and cardboard. A large water change and i was all good again. The biggest thing when blacking the tank out for suspended algae is aeration, make sure you got bubbles if you dont have a good skimmer. Also absolutely NO light to the tank! Dont look at it, not even for one second! Good luck.
