| | Re: What's Your best Algae Scraper?
I always use old credit cards. The only time they don't work easily is when I have green spot algae, which is almost never, since I dose adequate KH2PO4. The problem with any scraping of algae on the glass is with green dust algae, which is a free swimming form of algae. When it is scraped off it just stays in the water and re-settles on the glass, where it reproduces even faster. For that, I start draining the water for a water change, and use a folded paper towel to wipe the algae off the out of the water portion of the glass, usually wiping every 2 inches of exposed glass as the water level drops. The lower 50% of the glass remains in the water, so I again use a folded towel, but try to make only one pass over the glass with each piece of paper towel, so the wiped off algae is never rinsed off into the water. This has worked very well for me.
