Razor algae scrapper
 

Any idea where I can buy mini razor algae scrapper that does cost too much? C328 and Seaview dont sell.

Depending on what you want to scrap off - I usually use those old unwanted "credit-type" hard plastic cards such as those membership cards etc. Can be used for simple algae such as the diatoms and green spots. But even razor type scrappers have difficulties removing BBA. I happen to see these razor scrappers at Sam Yick Aquarium at marine parade central.

I use my DE Razor blades to scrape algae from the glass. Effective. But careful not to cut myself.

Daiso $2 brush is the best
