Algae growth on glass

[JJ-MIK]

Ok . This one is baffling me.. Has anyone ever seen this before? Coraline is only growing so high up and on the front of the tank. The film algae only goes up to the same height .. It's like the mountain tops in Colorado... Any ideas? You can see in the pics. The top 1/4 of the tank is bare

Though not an issue I've run into, when you look at the top it looks more like something is eating the coraline. You have anything in there that eats it?

 

[JJ-MIK]

I have turbos . But this is almost a straight line across the top of the tank. All the way around.

Ok, they wouldn't do enough for it. Might be the lighting? I don't have a real answer for you in all reality other than it's happening...but you can see that.

I thought about the lighting.. Thinking about it... It seams that that's the line that I do my water changes.. I draw out 30 gallons and that is right about how far I draw down the water ..

i have the same thing going on in my tank and nothing has gone wrong yet. so i wouldn't worry about it.

Does your water level ever go down to that level?

nope. my water level is all the way up to the black rim

I just did some more research. I read that basically . When you draw down your water and leave the lights on. It pretty much burns the caraline. If you were to expose say an sps with full power on your lights. It can burn it also

well, anything out of the water will sure die whether or not you have the light on. but like i said i have the water all the way up to the rim of the tank and the algae still only goes as far up as your tank. but i don't mind it, i just like it be the way it it.

Well could it be maybe a gas or nitrates or something? Do you have a deep sand bed as well?

my sand bed is 1.5inch to 2inches deep. i wouldn't say it's gas or nitrate as they have nothing to do with how high and whereabouts the algae grow

Just trying to help narrow it down for the Both of us.. Haha I'm guessing its got to be light intensity.. I'm running dimmables LEDs. Maybe par is too high in that area
