Help/Advice How do I get hard algae off acrylic? New to acrylic.
Hey folks, one of my tanks is a brightly lit planted acrylic 30 gallon. I haven't ever cleaned the glass because I'm terrified of scratching the soft acrylic and this is the only acrylic tank I've ever had in 25 years in the hobby. How do I do this? I know I can't use a razorblade like I do on my glass tanks. I tried using some aquaclear foam to rub it off with zero success. It's the tiny little green dots the really rock hard stuff. Even if it was glass and I had a blade I'd have to really put some elbow grease into getting it off.
What do I do guys? Is there a product I need to buy to help me clean this stuff? I'd rather not use any chemical type products like algae killers or seachem flourish excel etc as the tank houses my betta antuta and their fry and they are rare and priceless to me.
Thanks in advance and happy fishkeeping!
