Cleaning acrylic tank glass at my wits end

So I've never had an acrylic tank until recently only glass. When I get stubborn algae on glass tank razor blade sorted.

I've got a build up of green dust algae low near the sand bed and I can't seem to completely clean it off no matter how hard I try. And my snails while going over it can't remove it. I realize it's stubborn because it let it stay in difficult to clean spots to for long.

I've tried:
- magic eraser
- credit card
- plastic scrapper
- general float glass cleaner

Any ideas other than more elbow grease???

Get a mightymagnet, the only thing I use for my tank and it gets all algae off no matter how long it has been there. You will need to be careful with the algae so close to your sand bed to prevent sand from getting caught between the acrylic and the magnet and scratching you tank.

That's how it built up there wasn't gonna take the magnet cleaner that close but then obviously it built up.

I'm about to try sharpening the plastic scrapper and see if it being sharper will help

I've never met an algae (besides crustose coraline) that didn't come off with a magic eraser... albeit some required a lot of elbow grease!

That's why I went barebottom in my tank
 
I have always had issues with algae growth at the sand line. Happened with all my glass tanks, and now again with my first acrylic tank. I have just built the stand trim so that it comes about 3" above the sand line. That's way I can use it as a guideline for the external half of my MM cleaner and block any front view of algae buildup.
 
Use a hotel key card or an old credit card. Takes a bit of elbow grease but it works. I use them on my tank.

IME, credit cards are the best. Just realize that they lose their sharp edge rather quickly. Each card has 8 edges, 2 on each side.

I always kept fake credit cards, special offers and room keys when I had an acrylic tank.

I've been "˜sharpening' those plastic blades for years... the goal is to remove the rounded edge, and make it flat... I use a small plane from my exacto knife set and it works great
 
I use a Tunze Care magnet on my glass tanks, but have not tried it on acrylic, always wondered because it looks like it would work.
