So my girlfriends tank has an insane algae bloom. Two morning ago nothing then looked at it last night and its covered in algae all over the glass all green. But you leave it for a few hours and you can notice the difference we have lights. Water is Nitrate 40 Nitrite 0 PH 7.5 Tank temp 68 (they're goldfish). Also no light on this thing almost at all its in a basement room with two totally blocked up little windows. Anyways like I say this is out of control. She asked why not just scrape it off. I said we would and do a clean but we need to know why or it just happen again. Anyone know why and what we need to do to prevent it.

No light? Plants usually need light to grow.. not even an aquarium light?
I agree with the nutrients.. probably too many phosphates or other nutrients..
Is the water well oxygenated? Sometimes the respiration from the fish in a low o2 tank can make the Co2 go up which will fuel algae blooms..

Ok We are pretty tight on food for them but I'll have her reduce some more. Maybe we'll add some aeration to try and improve oxygen levels. The plants in that tank don't grow and most certainly don't require light. Thanks for help. Like I say in a matter of hours this thing got out of control no signs in the water we test her water pretty regularly and not a problem. I'll try the suggestions.
Just be careful not to have the algea crash the tank when it dies. Lost a $60 guppy trio plus another $30 worth of gups because of an algea bloom in summer.
Lots water changes to avoid crash. Just check water parms and they are still same. Added airstone to help with oxygen no lights for one day doesn't seem to have gotten any worse. Snail however looks like he is in snail heaven.
No lights should be bad for the algae, there must be some strong nutrients in the tank. I suggest removing as much algae as possible manually, then try to find the source of what the algae is feeding on. Might want to even consider some kinda shrimp or something to keep the alage under control. Although, I dont know if shrimp can survive in those temps.
