LONGSHOT question about scratches on glass

Yea, like the title suggests, I'm really not expecting anything from this. I think I'm just SOL.

I have neglected my cleaning a couple times and it resulted in some very tough algae growing on the front glass. Too tough for my magnetic scraper to clean off without due diligence. So a few times I have had to go in with my hand and scrub the stuff off myself with a sponge. Just your regular run-of-the-mill kind that you buy in grocery stores, the yellow soft side and green rough side ones.

Anyways I got a canopy (yay!) and because of that I have had to lower my lights. I never noticed all the scratches on the inside of the glass until now.

Is there any kind of reef safe...thing...for lack of a better word...that I can use to fix these? Or was I just dumb to use these harsh sponges and now I have to pay the price? I'm really thinking the latter... :-/

 

are you sure you have glass and not acrylic. i have a asian buffet called sino america with some hundred gallon tanks, they clean there glass with large guage steel wool (fiber is about have the size of film in a cassette tape). it may be i never paid attention but there glass looks pretty good still. green as hell though(probably cheapest quality glass you can get)


edit: i just thought that since its so green it probably has a higher iron content so it more scratch resistant so nevermind

 

you could try researching cerium oxide im not sure if its reef safe.

pro-tip: using a razor blade and going straight down to clean is a good way to remove tough algae. at certain hardware store they will sell plastic handles in the paint section for attaching the blade too. i use a metal one for coraline, i have to wash it after use it only last 2 months its stainless steel. but i will go to ace's hardware to track down a plastic one when i have time

 

I am cheap and use a old credit card card to do my scraping of alge and or coraline alge... This way it will limit the scratches in the glass/ acrylic or if i get any at all....

Good luck

 

If it is actually glass, you are pretty much SOL unfortunately. To get scratches out of glass, professionals will grind the glass down and repolish it, not something you want to do with fish tanks. If it's acrylic, then you can get buffing kits to remove scratches if they are inside the tank. Some are advertised as safe for in water use. I use the "Pro-Scraper" to get my tanks clean. They work great and don't scratch the walls at all.
