This tank is at my workplace. I haven't had any experience with an algae bloom in my home tank, assuming that is what this is. I'm not entirely sure, correct me if I'm wrong. The tank water is completely green.

What is the solution here?

Thanks in advance!

Yes….it appears you have an algae bloom. Get a Green Killing Machine and it will clear up in a few days. You put it in the tank and plug it in. Be sure to check the tiny intake sponge filter every so often. Do not have meds in the water during this time. You can wait it out, but why…..when you can do it faster?

UV will clear it, but green water comes straight back if whatever fed it is still there. On an office tank that is usually the lights running all day, plus feeding from whoever walks past it. Put the light on a timer at about 6 hours and check your nitrates before you unplug the UV again.
