How to get rid of coralline on my glass?

I have a 55gal that is 75% covered in coraline on the back glass. I have a scaper but I don't want to disturb anything by removing that much coraline and have it floating around my tank. Any suggestions or tips?

Leave it as suggested or I have always used a razor blade, and scrap and then net whatever floats.....

Why oh why does it accumulate so quickly on the front of my tanks?

It's funny, in two tanks, my front glass is covered, not the back, not the sides.

It has a lot to do with lighting. There is more lighting on the front of the tank, a lot due to reflection from inside the tank and the lighting from the room it's in. There is going to be more lighting at the front, then the back. At least that's my theory and I'm sticking to it, lol

You know that does make sense. Ironically, I'm using halide/t-5 fixtures and because of the effect (I wanted a little lower light area in the back so I could have corals all the way to the top) I have unscrewed both of the t-5 bulbs on the back of each fixture. This would have the more intense halide in the center and front, the lower light area in the back and sides.

That's a very good and likely possibilty. Any of that ambient light coming into a room through windows or what have ya would first come in contact with the front and sides of the tanks since the backs are usually up against walls. That light would then have to not only penetrate the glass on the front and sides but penetrate through the water as well to reach the back. I remember years ago I used to have a tank near a window and in the morning hours if the blinds were open some sun would shine on that side of the tank and would cause the algae on that side to grow like crazy on the glass. Finally put two and two together and moved the tank away from the window. That was back in the early days of my tank keeping experiences. These days I tend to keep tanks as far away from windows as possible.
To the O.P. I would scrape it off like and net the excess like sugguested earlier as well. I love seeing the coralline on the rocks but not a big fan of having it grow all over the tank, myself.

Do you clean the front of your glass every couple of days or every day? Your removing new deposits of the baby Coraline. Never allowing it to fully grow. The back of the glass I think we all agree we dont clean nearly as much as the front or sides so ti gives it more time to grow.
A razor blade is the best bet. The particals will settle faster then you think considering they are heavier then algae depending on size. If your still concerned about it you can place a water polishing pad in your filter to catch those tiny particals. You can even stick them in a hang on back filter. :) I use the Fluval pads

Usually after i scrape my coraline algea off the glass, i do a 5g water change (its a 29g tank)

Just an Idea. I use a glazers multi tool to scrape the Coraline algae of the glass. It is a little less invasive then the razor blade and has less probability of etching your glass. I don't know about the rest of you, but I have found that if the glass gets much etching, the alga's seem to grow easier in those areas. Its just my .02.
But I am glad I am not the only one who has a purple back to their aquarium right now.

i like the purple back, but sides and front i keep clean. coraline is a sign of good water quality

Well if you wanna go all out its also if its been introduced...if you have a top off system, if your calcium levels are stable, temp, salinity stability, lighting, and current...current is a big one too.

Coralline relies on calcium, among other things, to grow. Corals demand calcium and tanks that are heavily stocked with corals and other calcium dependent creatures, then the coralline growth seems to be much slower.

I thought it all had to do with lighting and calcium. Also how much calcium the rock itself contains contributes to how fast the coralline grows on it, as well as your CUC.
