Algae on back of glass

[reefguy40gal]

So I was given a 40gal. Tore down my 24gal nano and put all the fish/rocks into the 40gal.

It's been a few weeks and there is algae growth on the back glass of the tank. Being that it's a reef/fish tank.....there's no way I can get to the back of the tank to scrape the algae off.

What do you guys do? Will my tank look like crap in a couple of weeks? I got a massive skimmer/sump designed for a 100gal tank and I change 10gals of water every week religiously. I also run Chemipure (the new one) and huge pile of chaeto.

Nitrates are about 20ppm. Too high?

I typically just clean as much as I can get to with a razor blade or a scraper stick as close as I can
I let the clean up crew do the rest but I don't stress out if there are some spots of algae, it is a reef tank after all not a steril laboratory

I let it go. Actually, there is not enough for my abalone and lawnmover blenny.

My tank has two islands so I clean the back glass wherever I can reach. Whatever I can't see, I don't worry about and leave it for the fish

I use a three foot long scraper to clean the back of my 120 gal. I leave some for my lawnmower blenny.
