Brown algae

[Tomato the Betta]

Hey y’all I need some help. My goldfish were showing signs of light deficiency so I got a new light. They are doing better. However, I got a major brown algae bloom in my tank. Cleaning it is not a concern for me, I once got it in my betta tank and after a clean and a new pleco I haven’t had an issue in that tank. I can’t fit a pleco but I can clean this tank easily and be fine.
My question is why this happened. Is it because of the new light? Admittedly I keep it on all day because that’s what I do with the betta tank and I figured that’s what the fish need. Is that not a good idea? I know how to clean this algae and I’m not worried about getting rid of it, I’m mostly worried about a future bloom. Any advice? Is it because of the new light exposure? Just looking for some advice! Thanks in advance!

Oh yes, I know that stuff well.

it flourishes in the light, I’ve found that when I keep my pretty bright LEDs on all day it grows everywhere.
in my experience the brighter and better the light, the more of it there will be.
It will grow especially fast under a blue light from my experience.

I hope this helped!

This does help, I’m glad I’m not crazy. I never thought that my pleco was doing more then I thought in my betta tank.

if you don’t mind me asking, how often do you keep your LED light on? I want to keep it on for the fish but obviously I don’t want more

I keep mine on about 12 hours a day, and it’s pretty bright.
In one of my tanks that has a lot of plants keeping the light from hitting the bottom of the tank, there’s much less algae, even though the light is kept on the same amount of time as in my betta tank that has lots of the stuff.
