It’s very difficult to scrape coralline algae from an acrylic wall

[jimk60]

The only problem I see with letting it grow unchecked is that it consumes more calcium and alkalinity leading to extra dosing and therefore more dosing

I had a few guests tell me my tank looks very dirty because of all the coralline algae on the back wall.

My cousin even said, “why don’t you hire someone to clean it?”

Oof.

I used to scrape it meticulously, but it’s extremely difficult to scrape the overflow because it’s acrylic. The metal blades catch and snag on the overflow, and the plastic ones don’t make a dent on the coralline.

Does anyone have advice?

Who cares what they say.
I think it looks great, better than having gha on the back wall.
